New: Rizom-Lab RizomUV 2020 Spring Release Details
Spring 2020 Release
RizomUV 2020 Walkthrough
Rizom-Lab has released RizomUV 2020.0 Virtual Spaces (VS) and RizomUV 2020.0 Real Space (RS). These are the latest versions of its UV unwrapping applications. AskNK takes look at how to get started with this awesome tool.
What’s new in the RizomUV spring 2020 release?
We’re fortunate to have a community that keeps working with us to improve RizomUV. As well as algorithm improvements, here are the new features implemented since the Winter release from November 2019:
Texel Density Workflow Overhaul
We have made using Texel Density (TD) in RizomUV significantly easier by tweaking the UI and how it works. The functionality, complete with shiny new icons, is in the Layout and Packaging panels. But, the workflow is now a little different. Texel Density is now one, linked setting, as opposed to separate in earlier versions. Texel Density in the Packing Panel is now linked to the Layout Texel Density by default. However, should you need to set TD settings in the Packing panel, you can unlink them from the Layout Panel by pressing the Custom button and then defining your TD.
Texel Density in the Layout Panel
- In the layout panel, we now have a Texel Density picker as well as letting you add your values manually in the spinner.
- Using the pickers in both panels will let you pick TD from selected islands, If nothing is picked, it will select and calculate the average density for all islands
- Pressing the new Apply Texel Density icon (Shift+Q) will apply your defined or selected TD onto selected Islands
- Pressing the Apply Density Uniformly will apply a calculated average density across all (selected) islands
Texel Density in the PackingPanel
We have kept Keep and Average as they were, but we made the following changes to the workflow:
- Pressing Texel Density now matches the specified TD in the Layout Panel. It’s important to note that you need to turn off Autofit when using this option, as Autofit will override this setting and scale the islands to make the islands fit the UV tile(s) according to the Autofit and not the TD algorithm
- Pressing Custom, lets you pick or define a Custom Texel Density for Packing rather than using the Texel Density specified in the Layout Panel.
- Using Follow sets Packing to follow the average TD of non-selected and non-locked islands. As with the other settings, you need to turn off Autofit, so it won’t override scaling when packing.
Select Element works just like it does in, i.e. 3DS Max: you select the Element, and then you can, i.e. press I to isolate and unwrap it. The Element selection remains regardless of UVs, so you can always select it for further refinement or packaging. In the video below, we enter Island mode (F4) but you can use Polygon Mode (F3) as well. We then Selected an island of an Element. Then we pressed the Middle Mouse Button (MMB) but you can also use the icon in the top right of the align panel
Select Flipped does precisely what it says, it selects all flipped islands or polygons in a model or isolated group if you pressed I to separate something out. Rizom interprets Flipped components as downfacing in UV space. To select them, you press the icon, and hey, presto!
Once the islands or polys are selected, you can use any of the flip options in the flip menu, or you can press U to unwrap them if they are existing islands, that will also flip them the right way in many cases
After doing the spider OCD UVs by hand using the Align tools in RizomUV 2019 we decided to implement something similar to Photoshop’s Align/Distribute function as well. Here is how it works: In the Align/straighten/flip etc. menu in the lower right, you’ll find the new settings. You can distribute horizontally and vertically, and select an average, pixel, or real space for distribution
- You can distribute per average space available, which disables the spinner.
- Selecting Pixel space and defining the value in the spinner distributes your selection(s) according to that value. So if you set the spinner to 5 pixels, there will be 5 pixels between the selections
- Selecting Real Space and setting the value in the spinner distributes your selections according to that value. So if you set the spinner to 5 Real Space Units, there will be 5 real UV units between the selections
You can use this function on islands (F4), polys (F3), and edges (F2) .Vertices(F1).
The Group switch specifies if the primitives must be moved as solid groups or independently.
Autosave and debug logs
Located in Edit_>Preferences, RizomUV now has Autosave and Debug options. Autosave is off by default, but when you set it to on, it will save in a location of your choice (the default being RizomUV’s autosave folder in C:\Users\YOURUSERNAME\AppData\Roaming\RizomUV at intervals of your choice, and you can define up to five (5)autosaves. You can, of course, change the location of your autosave
Found in the same location, the Debug log for RizomUV comes in two flavors: The Command log outputs how RizomUV initializes and the commands used in the current RizomUV session you are running. The OpenGL log outputs what OpenGL is doing during your session.
Both will hopefully make troubleshooting even easier, and we urge people to add the command logs when reporting a problem at support.rizom-lab.com.
Edge Alignment Enhancements
RizomUV now has an option to keep constrained edges aligned when unwrapping or optimising. It can now also create a hinge from a vertex, meaning the alignment will “bend” based on the position of the vertex. Please note you have to be in Vertex mode for this (F1). It’s kind of like how you insert an extra point in a Marvelous Designer pattern and bend it straight from there.
In addition, based on a user request, we have implemented an Edge Selection Stop featurette, where Edge Selection stops selecting edges when it meets an already selected edge.
We’ve also given FBX loading some enhancements:
- Located in Preferences, you can now choose how RizomUV handles FBX imports and their channels:
- You can now enable partial FBX UV sets as well as delete unused UV sets
- In addition, the UV Map names are now displayed even if the FBX file is loaded in its default channel index mode. We added this, as all modelers handle what’s in the FBX channels differently, and we hope this makes it easier to work with them in RizomUV
Making UV Mapping even more of a snap, Rizom-Lab introduces the RizomUV Spring 2020 update
Marseille, France, May 2020
Firm believers in no-pain UV mapping, Rizom-Lab release their first major update of the year for their RizomUV UV-Mapper offerings.
Home of the phrase UV Zen, RizomUV has gained enormous traction as a staple UV Mapping tool for Indie as well as Studio pipelines over the last year. Built on some of the fastest and flattest UV algorithms around, RizomUV makes for fast and easy unwrapping workflows. The new release sports optimizations to its five auto cut and pack algorithms, new alignment tools, a Texel Density workflow overhaul. In addition, new and improved selection features, as well as several quality-of-life enhancements such as Edge Selection and FBX-based mesh improvements.
Team Rizom has also added three new members to its growing script library: A new script to handle preferences, another to handle multichannel mesh, as well as a new script to make dividing hair- or foliage card stacks easier. The RizomUV user community is also heavily invested in scripting, as shown by the frequent updates and support the creators provide for their C4D, Maya, Houdini, Modo, Max, and Zbrush bridges or LiveLinks.
Always focusing on the quality of unwrapping life for its users, Rémi Arquier, founder and owner of Rizom-Lab, and creator of all things RizomUV states:
“We’ve said it before, but it bears repeating: Quality of life is a top tier feature for us, on par with code. This is why we have implemented new features as well as code- and existing feature overhauls for this release. We’ve implemented new selection features as well as a much-requested Distribute feature-set for those in need of fine-tuned alignment and packing options. We also gave the Texel Density workflow a serious overhaul, and we implemented autosave and error logging options. We’ve also heeded user requests and enabled easier backface selection, as well as improving FBX-geometry-based workflows. For those big on automation, we improved the scripting panel and added three new scripts. Other quality-of-life improvements have also been made, such as additional selection options and Optimise function improvements.”
RizomUV is available on Windows, macOS, and Linux. The spring 2020 release offers the following workflow updates and enhancements in RizomUV VS for general 3D work, and RizomUV RS for CAD:
- New Distribute feature distributes Islands, Edges, and vertices similar to, i.e. Photoshop. This makes it much easier to work with your UV map’s layout as well as straighten “difficult” edges or verts.
- Redesigned Texel Density (TD) Workflow. The TD defined in Layout now carries to packing, and picking and setting your TD has been simplified
- Edge Alignment with Hinges Feature. In addition to Horizontal and Vertical constraints, RizomUV now has an option to keep constrained edges aligned when unwrapping or optimizing. Also, it can now create a hinge from a vertex, meaning the alignment will “bend” based on the position of the vertex.
- New Selection Features let you select Elements as you can in, i.e. 3DSMax, as well as the option to select flipped Islands only.
- Autosave feature located in Preferences, RizomUV now lets you autosave your work based on default or personal preferences
- Edge Selection Enhancements: Edge-constraints can now be added in vertex mode, with the additional benefit of hinged constraints. In addition, the Edge Selection Stop featurette stops selecting edges when it meets an already selected edge
- FBX format improvements. Users can now enable partial FBX UV sets as well as delete unused UV sets. In addition, the UV Map names are now displayed even if the FBX file is loaded in its default channel index mode.
- Raycast options. The ability to turn raycasting on and off makes it significantly easier to select back facing mesh

There are currently no plans to increase RizomUV’s price, which has remained static since 2018. Users can buy a variety of licenses: Student licenses have a permanent 70% discount. Indie pricing starts at a monthly 14.95 Euro, as does the annual rent-to-own. Annual licenses are 149 euros. Node-locked and Floating Pro licenses begin at 34.90 Euro. People needing an SDK license will need to contact Rizom-Lab. Each non-SDK license allows RizomUV to be installed on two machines. (Note: Toolfarm has the prices in US dollars).
A fast-growing startup, Rémi Arquier started Rizom-lab in 2016 and began releasing RizomUV late 2017. The name Rizom comes from the rhizome. A rhizome is an always growing, underground root system. And Rizom-Lab has no intention to.
The company is currently on a quest to create the perfect UV mapping toolset for any pipeline. The team is always looking to improve its already impressive capacity for flattening and packing UVs in seconds, not hours. And they’re always on the lookout to make sure the glue binding modeling and quality texturing is a pleasure, not a pain.
