Artist-friendly parametric modeling and layout for 3ds Max

RailClone is the world’s most powerful artist-friendly parametric modeling plugin for 3ds Max®. Its unique array-based approach to asset creation is fast, efficient, and easy-to-learn.

What Is iToo Software Railclone?

Tired of using fixed, hard to modify, assets that require time-consuming manual labor to edit? Wish it was easier to create smart parametric objects that are easy to update, can be used and reused again and again, but requires minimal time investment? Enter RailClone – the artist-friendly parametric modeling and spline-cloning plugin for 3ds Max that’s fast, efficient, and easy-to-learn.

RailClone is unlike any other tool on the market. Objects are created simply by assembling and repeating existing geometry using an easy-to-define set of rules. If you can model in Max, you can create procedural objects with RailClone

Choose from hundreds of built-in presets. Likewise, adapt existing objects by adding your own geometry. Moreover, create your own from scratch using RailClone’s easy-to-understand visual editor.


How Does It Work?

Learning Railclone Is As Easy As 1-2-3

itoo Railclone Base object

1 – Base Objects

Expressly, RailClone doesn’t construct an object from scratch. It works by assembling and repeating existing pieces of geometry along paths. To do this it needs two things: a spline for the path and, of course, some modular geometry.

itoo railclone rule generators

2 – Rule Generators

Imagine you’re explaining to a manufacturer how to build this bus shelter, you might say: “Put a glass panel at the start and the end, add mullions at 2m intervals, then fill in between with the roof and glazing.” If you understand this, you understand RailClone.

itoo railclone modifiers

3 – Modifiers

Just like Max, use RailClone’s own modifiers, called operators, to manipulate geometry. You can group items, create patterns, and randomize transforms. In addition work with UVs and materials IDs, create conditional relationships, and much more.

Key Benefits

Parametric Modelling Made Easy

Versatile

With RailClone there are no limits on your creativity. Unlike other scripts and plugins that are designed for a single type of model, RailClone can create almost anything.

Easy to use

RailClone uses an easy-to-understand visual Style Editor to create sophisticated structures. Unlike other tools, absolutely zero programming knowledge is necessary.

Fast!

RailClone is fully multi-threaded and highly optimized for speed. This, coupled with the efficient viewport display modes, and powerful instancing means that you can create and render huge objects, made from thousands of highly detailed parts.

Adaptive

RailClone assembles, transforms, slices and deforms geometry to create a seamless object. Just set a few rules, and the object is constructed for you automatically, even on curved paths!

Smart

Let RailClone do the thinking for you with advanced algorithms to deform geometry to follow sloping paths and surfaces. Inclined and uneven walls, stairs, handrails and balustrades, and stepped fences are no longer a chore to create in 3ds Max.

What´s Included

  • Plugins for 3ds Max 2012+
  • Native support for most popular rendering engines
  • Unlimited render nodes
  • Over 350 presets
  • Premium support

RailClone comes in 2 versions

RailClone PRO

To explain, the fully-featured RailClone Pro comes with advanced modes to deform geometry on the Z-axis. In addition, you get an unlimited number of segments and generators, RailClone tools, and the ability to convert the geometry to an editable mesh. The Pro version also includes the full library of other 350 style presets and the ability to edit libraries and add your own objects.

In addition, a Pro license of Forest Pack permits you to prioritized technical support, early access to beta versions, and regular updates.

RailClone LITE

RailClone Lite is free to use, even commercially. It provides many of the features found in RailClone Pro. Significantly there is a 3 segment limit, only 1 generator, and flat splines. The Lite edition has a limited subset of library styles and does not include RailClone Tools, the ability to collapse to a mesh, or user editable libraries.

If you want to know the differences between our Pro and Lite versions, please read this documentation.

You can download RailClone LITE from the link on the right side of this page.

Compatibility

RailClone Pro is compatible with 3ds Max 2013 and above with native instancing support for the following render engines: V-Ray, V-Ray GPU, Corona Render, Arnold (Max 2018 and above), and Mental Ray (Max 2012 – 2017). It can also be used with any other renderer via RailClone Tools or with the instancing engine disabled. Feature support varies for some renderers, for a full list please see this article.

Supported versions of 3ds Max and 3ds Max Design

Our plugins support the following 3ds Max 64 bit versions.

  • 3ds Max 2013-2021
  • 3ds Max Design 2013-2015

Supported Renderers

RailClone supports native instancing in the renderers and versions listed below

  • Mental Ray
  • V-Ray
  • V-Ray RT
  • Thea Render
  • Corona Renderer
  • Moskito Render

Mental Ray support in Max 2017 and 2018

From 3ds Max 2017 Mental Ray was an optional installation. RailClone for Max 2017 still has many dependencies on the Mental Ray libraries and is required by our plug-ins to operate correctly. Please make sure that Mental Ray is installed for 3DS Max 2017, even if you don’t intend to use it to avoid errors.

From 3ds Max 2018 Mental Ray is no longer included, as a consequence, RailClone’s native instancing features are not supported for Mental Ray in Max 2018.

  • Arnold 5.1 and above is supported from 3ds Max 2018 onwards. Please make sure the MaxToA plugin is up to date. You can download the most recent version from the Solid Angle website.
  • Mental Ray is supported in version 2012 – 2017 only.
  • V-Ray and V-Ray RT supported versions are 2.5 or greater for V-Ray 2, and 3.7 or greater for V-Ray 3, V-Ray Next and V-Ray GPU update 1.1 or above
  • Thea Render 1.3 and onwards.
  • Corona Renderer 1 and onwards.
  • Redshift 2.6.24 or above

Due to technical limitations, feature support varies between renderers.  Click here to view the compatibility chart.

For unsupported renderers, it is still possible to use RailClone using RailClone Tools to convert the objects to standard Max instances.

Licensing

Each purchase of RailClone Pro gives you access to a single perpetual license for creating and editing RailClone Objects, the full library contents, and free unlimited render nodes. For the duration of your maintenance plan, you are also entitled to premium technical support and upgrades.

What’s new in version 3.2?

RailClone 3.2 introduces compatibility with V-Ray Next, Arnold and 3ds Max 2019, significant enhancements to default scaling modes, a new supermarket library and several improvements to existing features.

RailClone 3.2 is a compatibility update to support the most recent version of 3ds Max, V-Ray, and Arnold – Autodesk’s powerful new renderer, included in 3ds Max from version 2018 and above.

In addition, we’ve taken the opportunity to include in some additional updates to make RailClone even more powerful and add extra options requested by artists to create amazing parametric models.

Thanks to the latest release, you can now use beveled corners with adaptive and count mode, sync random values between generators, use the sub-spline count in expressions, apply modifiers to nested RailClone objects, populate supermarkets with a new library and more

As usual, a Lite version of this release is freely available to download and use commercially.

Compatible with (nearly) everything! V-Ray, Arnold, Corona

RailClone 3.2 adds support for V-Ray Next, so you can take advantage of Chaos Group’s latest and greatest renderer. Enjoy speed improvements of up to 25%, use the new GPU architecture with its promise of doubling the speed of your GPU rendering, take advantage of the new adaptive dome light and much much more.

For the first time, RailClone is now also compatible with Arnold, Autodesk’s replacement for Mental Ray that was first included with Max 2018. Not only does Arnold support instancing with RailClone and most of the main features, it also supports RailClone Colour,  a new map type introduced in version 3 that enables you to randomize and tint bitmaps per-segment, or even colors on a surface.

We’re delighted to announce that the recently released Corona 2.0 also supports RailClone 3.2 so you can take advantage of its fabulous new bokeh controls, scatter CoronaVolumeGrid objects, and take advantage of its many performance improvements.

And don’t forget, in addition to these great renderers, RailClone also supports Datasmith, Mental Ray, and Thea plus nearly any renderer on the planet via RailClone tools. Check out the requirements page for full compatibility information.

Harmonised input names

Creating models with RailClone is simple when you understand the underlying principles. Internally, the A2S (two dimensional) array generator is calculated by stacking multiple L1S (one dimensional) arrays on top of one another – to form rows.

Harmonised input names

To help artists to understand the connection between the two generators, the A2S generator’s inputs have been renamed.  From this release onwards, the A2S generator’s Left inputs are renamed to Start, and Right inputs have been renamed End.

Library Updates

This release sees the addition of a new library containing food products that can be used to quickly populate shop and supermarket shelves. RailClone now includes a growing library of nearly 400 styles in 30 categories, with more planned for release soon!

Library Updates

In addition, we have included several new Macros that you can use to create your own similar styles in a quick and easy fashion. Just add the geometry and you’re good to go!

To accompany RailClone 3.2’s Arnold support, we have created Arnold materials for every preset. If you are using Arnold, this will be detected automatically and the correct materials will be used. Alternatively, you can force Arnold materials to load by selecting them from the drop-down list.

Use Bevelled Corners with Adaptive and Scale mode

RailClone can distribute default segments along paths using one of four modes. In the default Tiling mode, geometry is simply repeated and the final segment is sliced to ensure a perfect fit with the underlying path.

Sometimes though, you don’t want to slice geometry. The remaining modes allow you to use only whole segments. For example, using Scale mode you can stretch geometry between the start and end of a spline or between intermediary segments. Ideal where you need to recreate a sweeping effect

For repeated geometry, Adaptive mode intelligently adds additional segments and scales them all equally to fill the available space. No geometry is sliced for optimal instancing and you’ll never see half a segment or encounter an unwanted open edge.

Finally, you can take control and specify the exact number of segments to be cloned along a path section using Count mode.

The last two modes are incredibly useful, but always had a limitation: it wasn’t possible to use them in conjunction with beveled corners.

Thanks to RailClone 3.2, we’re happy to announce that this restriction has been removed and beveled corners can now be used with all 4 default modes!

Improved Randomisation

The random number node gives you a lot of choices on when to create a new value. Pick from per spline, per section, per Y row, per segment and more.

But what if you want randomized values to be the same between generators? Until now that wasn’t possible, but in RailClone 3.2 we’ve added the ability to synchronize randomized values between generators. This makes it much easier to split a style between multiple generators to create more sophisticated styles.

Other Improvements

Several other improvements are included in RailClone 3.2. The UVW XForm operator now has an option to rotate the texture around its center – perfect for randomizing maps with radial symmetry.

Update manager has seen several stability improvements and now includes the ability to install libraries from a network location. This can save multi-user offices from having to download the same content multiple times.

Nested RailClone objects can now have modifiers applied to them provided they are not reseeded per segment, and a SubSplineCounter variable has been added to expressions so that you can create conditional styles based on the order of sub splines.

To help with XRefing scenes, when using Free Object mode the full spline’s transformation is now ignored. In previous versions, only the position was being ignored.

To see the full list of changes, please see the release notes.

What’s new in version 3.0.7?

New Features

  • Added Macros. This feature allows you to create new nodes by creating sub-graphs. Macros to output numeric values, geometry, and generators are all possible.
    • A new Macro library panel is available in the Style Editor containing system and user-generated macros
    • Create or edit a macro by selecting a Macro node, right-clicking and selecting Macro > Edit
    • Input nodes allow you to determine the base objects used by a macro. These will become the macros inputs.
    • Output nodes allow you to determine the type of output generated by a macro. Choose from segment or numeric.
    • One or more Generators can be added to a macro.
    • Several examples are included, and you can save, share and import your own macros as well as adding them to a user library for easy reuse.
  • Added Update Manager, a new application to download and keep the software updated.
    • Libraries, Maps, and Macros have been removed from the setup program. Now are downloaded from the Update Manager.
    • It requires to log in with the username and password included with your license.
    • In the current version, the plugin is not updated from the application. This feature will be included in next updates.
    • Update Manager is launched periodically from 3DS Max, notifying the use of updates if there are any. You also can run it manually from General>Update or from the Start Menu.
    • Library, Materials, and Maps are moved to C:Users<user>AppDataLocalItoo SoftwareRailClone
  • A new algorithm to align Linear Generator with planar and closed splines. It computes initial banking angle (X Rotation in Generator) so segment’s Z axis is perpendicular to the plane formed by the first and last spline’s segment. This method works much better when creating frames, windows, etc.
  • Added Auto Align option to Array Generator->Extend X/Y Size mode. This option creates array aligned automatically with each sub-spline. This mode is very suitable for roof and panels.
    Two modes are available. For both modes, the Z axis is always perpendicular to the plane formed by the spline.

    • X –> XY: X-axis is parallel to the RailClone XY plane (considering local axis of the object).
    • to Spline: X-axis is aligned with first Spline’s segment (you can use “Make first” vertex and “Reverse” spline to modify alignment).
  • Added Generator A2S->Clipping Area-> Hierarchy Checking Mode. This option determines the way that RailClone processes stacked splines for Extend X/Y Size mode.
    • Complete uses the original RC2 behavior, stacked splines are alternatively included/exclude geometry
    • None treats each spline as unique, overlapping or stacking splines has no effect
    • ‘ By Material ID uses the material ID assigned to the splines to determine which belong to the same array.
  • Added RailClone Color: A new map type that is similar to Forest Color, providing random textures and tint to each segment.
    • Compatible with V-Ray, Mental Ray, and non-instanced geometry.
    •  The number of maps is increased to 20 (instead of 10 for ForestColor).
    • In future Forest updates, ForestColor and RailClone Color will be interchangeable.
    • Added “Color Seed” to Transform node. If not zero, the value is used as a random seed for RailClone color
  • Added Style Linking: This feature lets you link an RC object to another, so Style changes done on Master are dynamically reproduced on the slave.
    • The update is done when Style Editor is closed, importing a Library Style or manually clicking the ‘Update’ button.
    • Optionally material is also copied from the Master object.
    • Parameter values are copied from the master as well, except those have been modified by the user. This mechanism works in the same way than Library/Copy Style operations, and the behavior can be modified from “General” settings.
  • Added ‘Retain Value Mode’ to Numeric parameters. It overrides behavior for Retain value feature (used on Library, Copy Style, and Style Linking procedures):
    • Auto: parameter value is retained if has been modified by the user.
    • Local: retain always value of local parameter.
    • Global: parameter is always overwritten, copying the value from the master RC object.
  • New libraries: Roofing tiles, Hips and Ridges, and Cladding.

Improvements

  • Added support for V-Ray 3.6.
  • Added support for Max 2018.
    • Note: Mental Ray is not supported for this version.
  • New Max.time variable to returns the current time (in ticks).
    • Note: When Max.time is used in any expression, the RC object is updated at each frame. This may degrade performance.
  • List boxes in Parameters and Base Objects rollouts are resizeable.
  • Internal changes for compatibility with third-party renderers.
  • Note nodes have been rewritten. They are now resizeable, have user definable colors and can move child nodes.
  • Limit by ID can be used in Array generators when “Clipping->Extend X/Y Size to Area” is enabled.
    • In this way, the ID limit is applied to the clipping spline, not to the base X/Y splines.
    • The ID of first spline’s section is used for checking.
  • Added mode to Compose: In Sequence or Grouped :
    • In Sequence uses the default behaviour, following Segments in order.
    • Grouped uses the first Segment as Main, which defines size and placement in the Generator sequence. Other segments are placed stacked in same position, according to their alignment settings. Note: some advanced operations as Bevel Corner, are not compatible with Stack mode and can generate incorrect results.
  • Instancing is disabled for certain Library styles, when current renderer doesn’t support it.
  • Continuous mapping feature (Segment->Mapping) is completely rewritten. Now it should generate correct mapping under all conditions.
    • Due to the changes introduced, mapping may look different from RC2.
    • Segment mapping from non-converted RC1 objects doesn’t work anymore. You must convert these objects to RC3 format.
    • Origin of UV coordinates (U=0,V=0) is aligned with the base spline.
  • Added UVW Offset to Generators.
  • Added Y Spline mode to A2S Generator: defines what coordinates are used for the Y Spline: Y/Z or X/Y.
    • X/Y was the mode for RC2 objects. RC3 objects uses Y/Z mode by default, which is more logical.
  • Style->Operate On is changed to Quad by default.
  • More Generator parameters are available for exporting (specifically combo values).
  • Transform->Fixed Size is computed before applying other transformations (as Rotate or Scale).
  • Updated expressions engine to V3. Changes:
    • return <expression> ;
    • * ‘=’ changed to ‘==’
  • Added option to extract all Segments to the scene.
  • New dialog for Export Parameters/Attributes . It allows to change multiple parameters from multiple selected nodes (of same type).
  • Seed parameter now is animatable.
  • Added Pivot Offset to Transform node.
  • Added next properties to Arithmetic->Expression :
    • XSplineNextMatID : Material ID of next X Spline’s segment. With Corners, returns ID of segment AFTER the corner.
    • YSplineNextMatID : Material ID of next Y Spline’s segment.
    • SegmentXRole : Role of current segment in a Linear Generator. Can be used also within a row of an Array (0 = Undefined, 1 = Default, 2 = Start, 3 = Corner, 4 = Evenly, 5 = End)
    • SegmentYRole : Role of current segment in an Array Generator  (0 = Undefined, 1 = Default, 2 = Bottom, 3 = Corner (unused), 4 = Evenly, 5 = Top)
    • XVertexIndex : (index of X spline’s vertex)
    • XEvenlyNumber : Number of Evenly positions on X path.
    • YEvenlyNumber : Number of Evenly positions on Y path.
  • Modified the way that arrays are generated when using multiple splines. Previously rows were created using all splines (Row 1 of Spline 1, Row 1 of Spline 2, etc). Now one array is generated completely for each spline (Row 1 of Spline1, Row 2 of Spline 1, etc) allowing their row sizes to operate independently.

  • Conditional->Vertex can be used with Default slot. It checks the latest vertex before the Default segment.
  • Display->Use Geometry Shader is renamed to Use Instancing Engine.
  • RailClone Tools->Instantiate copies User Properties, Object ID and wireframe color of the source object (when present).
  • Added Segments Selector to Quad menu.
  • Added warning message to General->Stats to inform of features not compatible with instancing.
  • Installer supports multiple Max versions.
  • Improved handling of multi threading. Also fixed rare crash on certain conditions.

(*) Segments using these features can be instanced only in V-Ray, though these operators can be used with all render engines and RailClone Tools when Display->Use Instancing Engine is off.

Style Editor:

  • Multiple wiring support, selecting several nodes of the same type and dragging (e.g. to connect multiple Segments to a Randomize operator).
  • Added Segment->Right Menu->Clone Multiple. Clones a Segment multiple times, using objects from the scene as source.
  • Improved detection of hotspot for node wiring.
  • Style Editor can be placed at left side on multi-monitor configurations.
  • Randomize->Presence and Sequence->Counter parameters are available for exporting
  • Auto rename of Parameters and Base Objects on wiring.
  • Added result of Arithmetic->Expression on edit dialog.
  • Wires can be dragged directly over a node, connecting them to a default slot depending of the wire’s type.
  • Dragging between nodes outputs swaps their links.
  • All nodes include an On/Off exportable parameter. This parameter is independent of the clickable On/Off state.
  • All boolean parameter are available for exporting.
  • Clipboard file (rcclip.dat) is stored in a temporary folder.
  • Fixed: nodes with multiple inputs were keeping empty slots after links deletion.
  • Fix: added creation context menu for wires dragged from Clipping Area slots.

Library:
The following styles has been completely redone, using the new RailClone features and improved materials

  • Architecture->Exterior->Fences->Metal

  • Civil Engineering->Pavements->Curbs
  • Civil Engineering->Pavements->Sidewalk

See release notes for the full list.

What’s New in RailClone 2.3.4

  • Fixed: Y counter is not computed correctly when using clipping areas.
  • Fixed random crash with points-cloud mode in Max 2015.

RailClone 4

Note: RC4 requires 3DS Max 2013 and VRay 3.7 or later. Earlier versions are no longer supported. Please also note that due to significant changes to the core, random values in RC4 are different from RC3, you may get different results from scenes rendered using RC3.

New Features

  • Added Style->”Use Segment Material“.
    Get Material from Source Objects

    • When enabled, RailClone uses the materials applied to the source geometry, instead of its own material.
    • Currently this feature is available only for V-Ray and Arnold Renderer or if you convert to standard geometry using RailClone Tools. Other render engines can add support using our updated API.
    • For embedded Segments (those not linked to a scene’s object), a copy of the latest material used by the object is stored internally.
    • To modify the material of an “embedded” Segment, it’s necessary to export it to a scene object from the Style Editor, and pick the material from it.
    • Materials are applied only at render time . The viewport still uses the material assigned directly to the RC object.
  • Added a new spline modifier: RC Spline. It allows you to add markers directly to the spline that include several properties to position and control segments.
    Spline Modifier Room

    • You can choose the type of vertex for checking (Any, Corner, Bezier, Smooth,  or Bezier-Corner).
    • Distance and Percentage accept negative values.
    • When using Percentage with a specific vertex type, the distance is measured until the next or previous vertex of the same type.
    • For each field, you can define the label and data type (Integer, Float or Scene Units).
    • It lets you to define multiple Data Set by style.
    • Once defined, Sets can be selected from the RC Spline->”Data Set” combo box.
    • Sets listed in the “Data Set” combo are collected for all RC objects which have the spline assigned as a Base Object.
    • Selected Set is applied to all Markers in the RC Spline modifier. If you need different Sets in a spline, apply a new RC Spline modifier.
    • Markers: defines custom positions in the path, without needing to add more vertices. They do not affect the shape of the path.
    • The position can be specified by a percentage or an absolute distance.
    • Markers can be defined relative to the spline’s start, end or using a specific vertex number.
    • Each marker includes two custom data fields: an integer ID, and 9 multipurpose data fields
    • It’s possible to add multiples “RC Spline” modifiers to a spline.
    • In Generators, marker segments are used with a new slot (“Marker”). From the “Rules” tab, markers can be filtered by ID, or by specifying a modifier index.
    • Markers can be adjusted manually (select, move, delete, etc), at sub-object level.
    • Multiple markers can be created by clicking on the spline using the Create multiple markers button.
    • You can use the same data from the selected marker by enabling “Copy Data for new markers” .
    • Values can be used from Expressions using “XMarkerData”, “YMarkerData” attributes, as a zero based array (i.e. XMarkerData[0] to XMarkerData[8]).
    • User Data fields are customized from the RailClone Style->”Base Objects”->”Customize RC Spline”.
  • Added Nested Generators. This allows you to use the output of a generator as a segment in another generator or even in multiple other generators.
    Nested Generators

    • Expressions can use attributes from nested generators, in the following way: GeneratorName.Attribute
    • The Generator’s name must be normalized to be used in the expression (non-ascii characters, cannot start with digits, etc).
    • You can select all attributes available for a specific operator in the “Attribute” panel, with generator names already normalized.
    • If a Generator is renamed, the user is responsible for updating the expression. Same for using unique names in Generators.
    • In case of duplicated Generator names, RC uses the nearest node to the Arithmetic operator.
    • The pivot of the nested generator is always at world origin – if the RailClone object is not at world origin the pivot may be offset some distance from the resultant object. You only need to worry about this if you are changing the Alignment mode of the nested generator to Pivot using an intermediary Transform operator.
  • Added Generator->Cap Holes.
    Capping

    • With Clipping splines it’s not possible to modify the UVW mapping of the capped faces.
    • For this reason, these faces are always mapped using Box Mapping and Real World Map Size.
    • To get the same mapping in all faces, we suggest to use this type of mapping for your Segments (i.e. enabling Segment->Deform->Mapping->Real World).
  • Added a new Display Mode called “Quick Mesh“. This mode is similar to Mesh, but more efficient as it draws instanced segments in the viewport.
    Quick Mesh Mode

    • To work, the active render engine must also support native instancing with RailClone.
    • Several features are not visible on viewport such as the Material operator, UVW Segment Mapping modes, UVW XForm operator etc.
    • If the scene does not meet any requirements, it works exactly the same as Mesh mode.
    • Performance is better the more segments can be instanced. You can check the number of instanced segments using General->Stats.
  • Added a cache for the evaluation of Nodes.
    • Each Node in the Style is evaluated only when it is needed, reusing the result if a node doesn’t change.
    • This may improve the performance of complex styles, especially if nested generators are used.
  • Compose->Group was redone from scratch. Now composed items are handled in a similar way to Max groups.
    Group Mode

    • The size of a Composed Group is the bounding box of all segments enclosed in it.
    • To keep the position within the group, the alignment of all segments is forced to “Pivot” mode.
    • You can modify the behaviour of a group by adding a Transform node after the Compose operator.
    • Due to this change, segments Composed using Group mode in RailClone 3 may not convert well to RailClone 4. To fix this, add a transform operator after the Compose node and set the alignment for all axes to Pivot.
  • Style Editor changes
    • Wires are coloured according to their type: Green: base objects, Orange: geometry, Yellow: numeric. Coloring can be disabled from Preferences.
    • Improved wire connection with macros.
    • Nodes can be inserted on a wire by dragging the icon over it.
    • Automatic rewiring when a node is deleted.
    • Added “Insert on Wire” to the contextual menu, to insert a node on a link. (This option is visible only when there is a single wire selected.)
    • Added grid view and snap. Use Options->”Grid Setup” to configure.
    • Added “Select Children” to the node’s contextual menu.
    • Added Edit->”Select Unused”. Select unconnected nodes and their children, which are not used in the Style.
    • New nodes added to the Style receive unique names.
    • Optimized nodes graph evaluation. ( Modifications on non-connected nodes don’t trigger a rebuild of the RC object. The same is true for changes to Note nodes.
    • Added prefix number to the slots of Selector node.
    • The macros tree is now collapsed by default.
    • Spline/Surface nodes receive the name of the object when assigned.
    • Properties panel now is resizeable, and width limit is removed for all panels
  • New General->Statistics window with detailed data, information about each Generator and separate information for Viewport and Render.
  • Support for all new RailClone 4 features is added to the Rendering API.

Improvements

  • Improved stability for V-Ray IPR.
  • The Selector operator has new modes that make it easier to use spline attributes to choose geometry, they include: X Spline Next Material ID, Y Spline Material ID, Y Spline Next Material ID, X Spline Marker ID and Y Spline Marker ID.
  • Huge improvement in instancing efficiency when using shared segments or linked styles.
    Performance Improvements

    • In RC3, each RailClone object kept its own copy of segments, but in RC4 the cache is global for all RC objects.
    • This lets to the render engine to create a unique copy of each Segment, for all RC objects.
  • The Material operator can now be used with instancing support in all render engines and with instantiating using RailClone Tools.
  • Style->”Operate on Tri/Quad” is removed. Now geometry is always computed as quads.
  • The order of Transform nodes is now taken into consideration when applying translation together with other transformations, this should result in more intuitive behaviour when multiple Transforms are chained together.
    Crane Demo

    • For example, Translate + Rotate will produce a different result from Rotate + Translate.
    • In previous versions, all translations were accumulated and applied after rotation and scale.
    • To keep compatibility with previous scenes, this change is applied only to new RC objects.
    • If you want to “upgrade” your RC object so it works as created with RC4, select it and run from Maxscript: $.railclone.resetCreatedVersion()
  • The Transform operator now applies scaling before rotation, to avoid skewing.
  • A new parameter allows the user to offset generators on the X Axis.
  • RailClone Tools->”Separated Meshes” is on by default.
  • Improved performance in Styles using Segments with exported parameters. Now Segments are updated only when parameters change.
  • Added new mode to Random node: generate on “Generator”.
  • Generator->Y Size can now be randomized by attaching it to a Random node.
  • Expressions have several improvements.
    • “XSplineMatID” can now be used in expressions to control the Y Size of a nested generator
    • Added “XSectionNextLength” and “YSectionNextLength” to Expressions. It returns the length of the next spline’s section
  • Added Generator->Rules->Default->”Scale Padding“. When enabled, padding is scaled on Scale/Count/Adaptive modes. If not, padding is constant.
  • Macros library folder now can be defined using an environment variable (It has the same effect as [HKEY_CURRENT_USER\Software\Itoo Software\RailClone Pro\MacroDir], but accepts a unique path entry.
  • Improved detection of circular references. Circular references between nodes are not allowed. This situation displays an error in the Style rollup.
  • The behaviour of “Free Object” mode with A2S Generators and “Extend to XY Size” enabled has been improved. Now the clipping area is aligned to the origin of the RC object, and doesn’t change when area moves.
  • For Floating Licenses, a license is now released on Max Reset.
  • Transform node generates an empty segment when input is not connected and Fixed size is on. This is especially useful to generate empty segments within macros.
  • Improved efficiency of RailClone Tools→Instantiation. Segments shared between different RC objects can now be instanced to a unique object.
  • In the style editor, the Properties panel now is resizeable, and width limit is removed for all panels.
  • Support for V-Ray 3.7.

RailClone 3.3.0

  • Added support for 3DS Max 2020.
  • Fixed: Shortcuts and Toolbars using RailClone actions are not initialized at startup.

New Features and Improvements

  • Added support for V-Ray Next
  • Added Support for 3ds Max 2019
  • Added Support for Arnold 5.1 and above

Includes RailClone Colour support

  • Updated library with Arnold materials
  • Added Supermarket products to the free library. Include 10 new presets, each with multiple product variations.
  • Bevels now can be used with Count mode
  • Bevels now can be used with Adaptive mode.
    • “Bevel Mode” and “Bevel Offset” have no effect. In all cases is used the same type of bevel with offset 0.
  • Added “Sync between Generators” to “Random” node. It lets to generate same random values for all Generators.
  • Added UVW XForm->”Rotate about Center”.
    • It has no effect with Segment’s mapping.
    • To make it work identically to the UVW XForm Max modifier, now Scale is applied after Rotation (previously Scale was applied before Rotation).
  • Added improvements to Update Manager.
    • Update manager can be configured to check if a library has already been downloaded to a network locations. This can save multi-user offices from having to download the same content multiple times.
  • iToo Toolbars (both Forest and RailClone) can be disabled adding the following registry key:
    HKEY_CURRENT_USER\Software\Itoo Software\DisableToolbars = 1 (DWORD)
  • Modifiers in RailClone objects are used on nested objects.
    • Only if Segment->Nest is not enabled in the outer object. This mode is not compatible with modifiers.
  • Added “SubSplineCounter” to expressions.
    • Index of sub-spline when using compound X splines. Valid both for array and linear generators. Starts in 0.
  • Several array inputs have been renamed, to more understable names according its operation.
    • Left Side -> Start, Right Side -> End, Top Side -> Top, Bottom Side -> Bottom, Inner Corner -> X Corner, LT Corner -> Start Top, RT Corner -> End Top, LB Corner -> Start Bottom, RB Corner -> End Bottom
  • For “Style->Free Object” the full spline’s transformation is ignored (Position/Rotate/Scale), not only Position as before.
    • This fixes a problem with XRef scenes binded to a rotated object.
    • Existing scenes may be affected if were using the Rotation or Scale of the spline. This can be fixed re-aligning the RC object with the spline (ie. using Alt+A) for rotation, and applying a Reset XForm to the spline, for scale.
  • Added warning when using Point-cloud mode with nested RC objects.

Fixes

  • Fixed: Bevel Extend and Symmetric options are swapped.
  • Fixed: When Evenly->Mode parameter is exported, modifies value of Clipping->Mode.
  • To fix it on existing styles it’s necessary to recreate the Generator.
  • Fixed: Evenly mode generates extra segments on closed splines.
  • Fixed: unable to export parameters with same name.
  • Fixed: Update Manager doesn’t close properly when launched on silently mode.
  • Fixed: Display->”Use Instance Engine” has no effect in Arnold (always is on).
  • Fixed rare crash in Expression Editor with some operations (i.e. using Undo when focus is on viewport).
  • Fixed issue when Evenly distance is lower than the Evenly Segment size.
  • Fixed: Sequence and Material->Sequence operators start with 2 same segments.
  • Fixed: animated Clipping splines are not updated correctly.
  • Fixed: Style Editor is not closed automatically when RC object is deselected, if an expression is being edited.
  • Fixed bugs with No-Bend segments and Y Splines in Arrays.
  • Fixed issues with auto alignment to X->XY.
  • Fixed crash using Numeric nodes copied from a macro in the main style.
    • Numeric nodes of main and macro styles are not interchangeable. Now RC blocks this possibility in copy-paste operations.
  • Fixed: Input macro nodes of different types can be rewired.
  • Fixed: Macro outputs cannot be rewired with a node of same type.
  • Main configuration of the plugin can be defined using environment variables:
    • Each registry key used in the configuration may be replaced by a variable, replacing non alphanumeric characters by ‘_’. 

      For example: for “HKEY_LOCAL_MACHINE\SOFTWARE\Itoo Software\RailClone Pro\MainDir”, you must define the variable “ITOO_SOFTWARE_RAILCLONE_PRO_MAINDIR”
    • The minimum variables to run RailClone Pro are the following:

      For Network licenses:    ITOO_SOFTWARE_RAILCLONE_PRO_MAINDIR=C:\Program Files (x86)\Itoo Software\RailClone Pro
      ITOO_SOFTWARE_LICENSES_LICENSEDIR=C:\ProgramData\Itoo Software\Licenses
      ITOO_SOFTWARE_RAILCLONE_PRO_USELICSERVER=1
      ITOO_SOFTWARE_RAILCLONE_PRO_LICSERVHOST=192.168.1.20
      ITOO_SOFTWARE_RAILCLONE_PRO_LICSERVPORT=16720

      For Stand-alone licenses:
      ITOO_SOFTWARE_RAILCLONE_PRO_MAINDIR=C:\Program Files (x86)\Itoo Software\RailClone Pro
      ITOO_SOFTWARE_LICENSES_LICENSEDIR=C:\ProgramData\Itoo Software\Licenses
      ITOO_SOFTWARE_RAILCLONE_PRO_USELICSERVER=0

    • If you define the variables in a .BAT file, be sure to not include any space at both sides of the ‘=’ symbol, or it will not work (this is a known Windows issue).
    • Environment variables are used only by the Max plugin. Other tools as the License Manager requires configuration registry keys stll.
    • If both registry keys and environment variables are defined, the variables have precedence over keys (priority order is Variables->HKLM->HKCU).
  • Fixed problems with Adaptive mode.
  • Fixed precision error when segment ends just at the spline’s limit.
  • Fixed crash in Style Editor dragging a Macro category (not a macro) from the Macros tree.
  • Fixed Style->Geometry->Vertex Weld, which was broken in latest release.
  • Fixed: in Point-cloud mode, Z-Offset is applied twice for segments with Bend off.
  • Fixed bug computing Corner on first vertex of closed splines.
  • Fixed resizing Note nodes when Style Editor is zoomed.
  • Fixed “Simple Y Offset mode” with collinear vertices.
  • Fixed bug when using “Extend X/Z Size to Area” and “X–>XY” mode with splines coplanar to XY.
