Cycles for Softimage
Plugins linking to this thread: (hide)
Sycles 2.4.1 V 2.4.1 released August 2026 —
This is a full integration of the Blender Cycles renderer into XSI. Version 2.4 is compiled with Cycles 5.3 (state of July 2026). The second generation of the addon (since 2.0) is a complete rewrite and works with Softimage 2015 SP2.
New since version 2.1.3 (from the github release notes): 2.4.1: fixed incorrect transforms of instances when the master model has rotation or scale, repacked with missing DLLs 2.4: Cycles 5.3. New Alpha parameter for the ImageTexture node, Sky Texture with Single and Multiple Scattering models, Thin Film for Metallic and Glass BSDF, new Raycast and Scene Time nodes, OSL custom camera, Linear 3D curve shape (also as per-object override), Geometry Approximation mode for NURBS surfaces, Render Time pass (CPU), texture optimisation (resolution, limit, tx texture cache) and a detailed scene export timing log 2.4: renders MaterialX shader trees from the MaterialXSI addon (converted to OSL). Note: OSL shading works on CPU render devices only 2.3.x: Cycles 4.5, OSL support is back, new Metallic BSDF and Set Normal nodes, phase function for Scatter Volume, Diffuse Roughness for Principled BSDF, more Noise Texture types, subdivision with motion deform, per-frame texture images, rendering of NURBS surfaces and curves (via custom properties), tile rendering, fixed shadow catcher, vector input ports for OSL shaders 2.2.x: nodes of Blender 4.3 (Ray Portal BSDF, Sheen BSDF, Gabor Texture, redesigned Principled BSDF), current Blender OCIO color profiles, custom velocity grids for VDB primitives, Particle Info node fed by ICE attributes, denoising of the final passes with OIDN or OptiX
Supported Softimage features (quoted from the download page):
Polygon meshes and hair geometry Texture coordinates Vertex colors Shaderball preview. For materials, shader nodes and texture nodes Basic limited support of the following built-in Softimage shader nodes: Phong, Lambert, Hair Shading, Image, converters between vector, color and scalar Ambience global environment light Limited support of built-in Softimage light sources Model instances ICE strands geometry ICE pointcloud instances ICE geometry attributes (vector, color and scalar) with context per-point and per-object Volume rendering. In particular supports emFluid, Explosia FX and openVDB for Softimage volumes Special VDB Primitive for rendering vdbs without ICE Output multilayered exr file with all rendered passes Rendermaps
The following features from Cycles itself are supported: CPU and GPU rendering. In particular multidevices are supported. This allows you to use cpu and gpu simultaneously. The libraries for GPU rendering are included in the package. All Cycles shader nodes OSL shaders OpenColorIO profiles (Blender profile included) All Cycles output passes (Combined, Depth, Normal and so on) Color and value shader AOVs Lightgroups Cycles camera properties, in particular all panorama modes Cycles light sources Denoising by using Open Image Denoise and OptiX denoiser
For more information, full documentation and a list of the available Cycles nodes see the download page linked below. There is no local backup because the addon is still frequently updated - the plugin can be downloaded on Shekn's github releases. The source code is available on github there as well.

Re: Cycles for Softimage
One more thing, can the SToon be updated to work with this version? I know that SToon is mainly OSL, but easy toon crashes the render, so does the line deterministic and every other SToon node.
