Redshift Features

Core

Out of core geometry and textures

Redshift’s efficient memory management allows rendering of scenes containing hundreds of millions of polygons and TBs of texture data.

Global Illumination

Achieve blazingly fast indirect lighting using biased point-based GI techniques, as well as brute-force GI.

World-leading performance

Harnessing the raw power of the GPU and using intelligent sampling techniques makes Redshift the worlds fastest renderer.

Proxies

The user can export groups of objects and lights to Redshift Proxy files which can be easily referenced by other scenes. Proxies allow for powerful shader, matte and visibility flag overrides as often required in production.

Transformation and deformation blur

Redshift supports multi-step transformation blur and 2-step deformation blur.

Volumetric rendering

Redshift support OpenVDB rendering in all 3d apps and native volume rendering in Houdini. Redshift lights can cast volumetric lighting around them.

Hair rendering with ‘Min Pixel Width’

Thin hair can produce noisy renders. Redshift supports ‘MPW’ rendering which smooths out the look of thin and hard-to-sample hairs.

Tessellation and displacement

Redshift’s tessellation supports edge and vertex creasing with separate UV smoothing control.

Per-object flexibility

Objects have advanced matte features and tracing options such as self-shadowing and primary/secondary ray visibility.

Baking

Redshift allows for any type of AOV data to be baked out from individual objects.

Command-line rendering

Users can export their scene and render it independently of their 3d app using the redshiftCmdLine tool.

SDK

A C++ SDK is available for studios that require deeper integration of Redshift with their pipelines. Please contact us for more info.

Altus Denoiser

Direct integration with the Altus denoiser from Innobright to further reduce render times while maintaining high quality clean images.

Redshift CPU (New)

With the initial release of Redshift CPU, any Cinema 4D user can view, modify and build projects using Redshift – without the need for specialized graphics hardware or an extra subscription. Redshift CPU offers an interactive experience when developing the look of your project, and pixel-perfect compatibility with high-performance Redshift GPU rendering.

Shading

Physically Based Materials

Flexible, production-ready shader, compatible with PBR workflows of Allegorithmic Substance and Unreal Engine.

Ray switches

Control how materials behave for certain ray types. Useful for customizing GI or double-sided polygon shading.

Hair shader

Accurately simulates light scattering off of and in hair with a physically principled model, yet offering artist-friendly controls.

Dedicated Skin Shaders

Support for up to 3 layers of sub-surface scattering in a single shader for realistic looking skin.

Round corners

Get smooth edges without requiring geometry tessellation. This technology is licensed from NVidia.

Displacement mapping with ‘auto-bump’

Add geometric and lighting detail to surfaces using displacement mapped height, vector textures or procedural shading nodes.

No texturing limitations

Virtually unlimited number and size of textures regardless of VRAM. Built-in efficient UDIM/UVTile tiling support.

Powerful shading attributes

Shaders can access per-vertex (weight maps, multiple UVs, etc) or per-object attributes for maximum flexibility.

Sprite node

Render foliage and other opacity-cutout effects blazingly fast!

Large variety of nodes

Redshift supports many dcc shading nodes for math, color ramps, color remaps and conversion, gamma and many others.

Distorter Node (New)

Cinema 4D’s Distorter node is now part of Redshift in Cinema 4D. The Distorter shader can be used to drive distortion of the UV space for a material according to texture or shader input, immediately producing variation to break up repeating maps. The Distorter node now supports 3D distortion using Maxon Noise. This means that Distortion is no longer limited to color texture inputs and 3D distortion of the popular Maxon Noise node and distortion of bump maps is now possible.

MatCap Shader Node (New)

Quickly create stylized, non-photo-real materials by mapping an image onto a mesh. This Shader allows you to prepare beautiful illustrative renders from your own digital sketches.

Jitter Node (New)

Automatically apply color variation across a large number of objects with the same material applied. Great for creating foliage, rocks, a mason jar full of gumballs or a crate of delicious avocados of varying degrees of ripeness. The Jitter Node is currently available for most DCCs (Cinema 4D, ZBrush, 3dsmax, Maya, Houdini, Katana, Blender).

Standard Surface

Redshift’s Standard Surface offers incredible realism with intuitive controls. Create surfaces via simple, industry-standard parameters, and translate materials from other rendering systems with ease.

Lighting

Dome lights

Efficiently light an entire scene using image-based environment textures.

Mesh lights

Use any mesh in the scene as a light source, with the same features and sampling efficiency as regular area lights.

Volumetric lighting

Redshift lights can affect atmospheric volumetric fogging for the popular ‘God ray’ effect.

Physical sun and sky

Natural-looking physical sun light and sky emulation.

Physically correct lights

Full flexibility ranging from area lights to photometric/IES lights, ‘portal’ lights and texture-projected ‘gobos’.

Cameras

Multiple camera lens types

Fisheye, spherical, cylindrical cameras, lens distortion.

VR

Stereo Spherical rendering for VR applications.

Physical lens effects

Familiar photographic exposure controls such as ISO, shutter, vignette, color balance and textured bokeh depth-of-field.

AOVs

Deep and Layered EXR support

For 3d compositing and efficient management of AOVs.

Many AOV Types

Material shading components (albedo, diffuse, reflections etc), depth, motion vectors, puzzle-matte and many more.

• Redshift is now available for the latest version of Maya on Windows machines, with support for other operating systems coming soon.

• Redshift Camera and Backplates are now available in Redshift for 3DS Max. Now 3ds Max users can easily apply different backplates for each camera, either in-render or as a post-effect, with robust frame fitting and adjustment options.

• New material preset for Principled Hair added for Cinema 4D makes it even easier to get up and running with physically-based hair. More realistic hair with nuanced settings for texture and shape variation can now be created with just a few clicks in the Material Manager while Redshift is active.

• Redshift CPU rendering is now faster in all host software packages, with significantly lower memory requirements (50% on average).

• General performance and stability updates for improved performance in 3ds Max, Cinema 4D, and Houdini.

• Added support for animated vertex deformation with motion blur in Redshift for Blender.

Redshift 3.5.15 – May 15, 2023

• AMD GPU support is now available (in public beta) for Redshift 3.5.15. Artists employing the industry’s most powerful biased renderer can now take advantage of select AMD Radeon™ PRO graphics cards GPU-accelerated rendering. The new loop option for Maxon Noise Procedurals allows artists to quickly set up seamless and satisfying animated effects.

• The Flakes Shader is now available in all DCCs supported by Redshift allowing artists to create sparkling car paint, beautiful shimmering snowdrifts, or add a light dust of glitter to concrete for an extra pop.

• Cinema 4D’s Distorter node is now a part of Redshift in Cinema 4D. It drives distortion of the UV space for a material according to texture or shader input, immediately producing variation to break up repeating maps or as a dream-like effect on its own.

• In conjunction with the new Redshift Camera, the flexible compositing options of custom Backplates, introduced in 3.5.14 for Cinema 4D, are now available in Houdini, Katana, and Blender. Anyone can easily apply different backplates for each camera, either in-render or as a post-effect, with robust frame fitting and adjustment options.

Redshift 3.5.14 – March 23, 2023

Redshift 3.5.14 brings a fantastic new Sky and Sun Model, Flakes Shader and new Camera Backplates in addition to workflow improvements and stability enhancements.

• PRG Clear Sky model allows artists to simulate gorgeous sunsets with Redshift’s improved Sun and Sky. It provides the most accurate simulation of sky radiance and color, offering rich red sunsets as the sun dips just below the horizon.
• The new Flakes shader is great for rendering everything from metallic car paints to glitter-filled superballs. This 3D shader generates Voronoi- or dot- shaped flakes at random angles and surface depth to add the perfect detail and shine to your renders.
• Custom Backplates are now available in Redshift for C4D, offering amazing compositing control. Artists can choose whether background footage is incorporated into the render or added before and after post effects. Renders can be matched to an existing backplate thanks to the Post-Composite mode.
• Cinema 4D 2023.2’s updated Node UI makes it a joy to craft Redshift materials. The UI is much cleaner, with new commands to select upstream and downstream nodes. Use C4D’s Preset system to easily apply your favorite node settings and build networks quickly with a new option to keep wire connections while duplicating a node. New pop-out panels make it easy to browse and add nodes as well as edit node attributes.
• The Redshift Camera is now available in Houdini and Blender offering simple physical controls to modify exposure, focus distance, motion blur and bokeh.

3.5.11 – December 2022

Redshift now features more realistic volume rendering, additional shaders and a new denoiser.

• Render volumes that look more realistic than ever with multiscattering. From clouds and smoke to new Cinema 4D Pyro simulations, multiscatter offers a more realistic representation of light bouncing within the volume, especially when combined with anisotropy.
• Cinema 4D’s popular Tile and Brick shaders are now available within C4D as native Redshift shaders. Easily define weaves, mosaics and tile patterns using many different shapes. Lay bricks faster than any stone mason, with full control over brick size, offset and displacement. These powerful shaders offer amazing procedural options for architectural surfaces and abstract motion graphics!
• Eliminate fireflies and smooth out samples on any system with Intel’s Open Image Denoiser. Intel’s Denoiser uses powerful AI to clean up renders, speeding up render times. This new Denoiser is currently available in Redshift for Cinema 4D and will come to other supported DCCs soon.

Important information for Cinema 4D:
This release introduces a change to the data to render settings and shader parameters. The plug-in will perform the necessary data conversion automatically when an older scene is detected. Once a scene is saved, it may become incompatible with previous versions of the plug-in. So we recommend that you keep a backup of your scenes before using them with newer versions of the plug-in.

Important Information

This release introduces a change to the underlying data for RSVolume shader parameters.
The plug-ins will perform the necessary data conversion automatically when an older scene is detected.
Once that scene is saved, it will become incompatible with previous versions of the plug-ins.
Please keep a backup of your scenes before saving them with version 2.6.23.

Important Information for Cinema 4D:
Releases 2.5.66 onward introduce a change to the underlying data for certain shader node parameters.
The plug-in will perform the necessary data conversion automatically when an older scene is detected, and a message will be displayed. Once that scene is saved, it will, unfortunately, become incompatible with previous versions of the plug-in. So we recommend that you keep a backup of your scenes before using them with newer versions of the plug-in.

Release notes
* [Maya] Fixed bug that resulted in Maya crashing under certain conditions when editing the hue of a color
* [Houdini] Support of the $N and $N4 variables in the RS ROP node.
* [All] Fixed recently introduced bug (2.5.70) that could cause a crash when rendering meshes with mixed displacement materials
