Redshift is the world’s first fully GPU-accelerated, biased renderer.

Redshift is a powerful GPU-accelerated renderer, built to meet the specific demands of contemporary high-end production rendering. Tailored to support creative individuals and studios of every size, Redshift offers a suite of powerful features and integrates with industry standard CG applications.


Highlights

Works with your software

Redshift works with a number of industry standard applications for a seamless integration into your pipeline

  • Autodesk Maya
  • Autodesk Softimage
  • Autodesk 3DS Max
  • Cinema 4D
  • Houdini

Core

Redshift has the features and uncompromising quality of a CPU renderer, but at GPU rendering speeds. Unlike other GPU renderers out there, Redshift is a biased renderer that allows the user to adjust the quality of individual techniques in order to get the best performance/quality balance for their production.

Out of core geometry and textures

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

Global Illumination

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

World-leading performance

World-leading performance

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

Proxies

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 a powerful shader, matte and visibility flag overrides as often required in production.

  • Transformation and deformation blur
    Transformation and deformation blur
  • Redshift supports multi-step transformation blur and 2-step deformation blur.
  • Volumetric rendering
    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.

Redshift SDK

SDK

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

Shading and texturing

Redshift supports complex, advanced shading networks and texturing capabilities as required for production-quality rendering.

Shading and texturing

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
    redshift Hair
  • Multi-lobe anisotropic specular using the physically-based Marschner BRDF.
  • Dedicated skin shaders
  • Support for up to 3 layers of sub-surface scattering in a single shader for a 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.

Lighting

Choose from a wide variety of light types. All lights are multiple importance sampled for the cleanest results using the fewest samples. Redshift also supports per-object light/shadow linking for great artistic control.

  • 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 sunlight and sky emulation.
  • Physically correct lights
  • Full flexibility ranging from area lights to photometric/IES lights, 'portal' lights and texture-projected 'gobos'.

Cameras

Redshift supports all commonly used camera types, as well as advanced controls for physical camera effects.

  • 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

Redshift supports a comprehensive set of AOVs for the most demanding post-production compositing needs.

  • 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.

There is a learning curve but it’s a huge time saver. It has cut some of my render times by 80%. You will need a high end graphics card to fully appreciate this render.

Would you recommend this product to a colleague? Yes

V2.5.71 is now available.

This build includes plugins for Maya, 3ds Max, Houdini, C4D, Softimage and Katana

Click here for online documentation (including setup instructions)

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
