Cycles for Softimage

Sycles 2.1.3Author: Shekn @si-community
V 2.1.3 released August 2023 —

This is a full integration of the Blender Cycles renderer into XSI. This update is a complete rewrite for the latest Cycles version from 2023 and has support for the following 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 buil-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 poitcloud 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 passe Rendermaps

The following features from Cycles itself are supported: CPU and GPU rendering. In particular multidevices are supported. This allows to use cpu and gpu simultaneously. Note: This distribution does not contains libraries for gpu rendering. You can download it from here. Unpack the archive and place lib folder to the /Sycles_2_1_2/Application/Plugins/ folder near the file config.ini 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 well.

Apologize, but i found how to render ICE instances only. A standard instance , like duplicate as INSTANCE a object , i'm not able to render it.
I'm doing something wrong probably. Please can you tell me what to do exaclty if don't disturb too much :D

Ok, this is the bug. Instanced models are not rendered. I will try to fix it.

Hi,

Just tested one of my old presets, and extracted the thumbnail. It ends up as a 64x64 px .bmp file, 32 bit.
I don't know what version of Softimage you're using for the generation, but maybe use an older version of Softimage just to check?

Small update 1.7.4. Download here: https://ssoftadd.github.io/download/Syc ... 4.xsiaddon

Only bug fixes. In particular, now Sycles renders model instances (as requested by yashugan). Also adds menu to the Material Manager for the quick creation of simple materials. Simply click on the menu item and new material will be added to the active library.

Thanks a lot for the update and Cycles access :)
Actually not too much time to work the cycles thumbnails but I will do something ...

Well it is really a pain to create these materials and very time consuming like Rork said :(

That's one reason I stopped doing this after the Lume toolbar ;)

Didn't found how to create a foggy/dusty/noisy atmosphere for the whole scene from a cycles light or light object.
There is nothing in the manual. It seems it exists in Cycles for Blender.

Is there any tip ?

You should create background light object and add ScatterVolume shader node to it. See the picture with example.

Hey Shekn

Some shaders are not working with the update 1.7.4 like blendermada with 1.7.3 it works.

Yes, this is actual a bug. It happens because the render does not properly recognize color values in the shader compaunds. For quick fix you can connect color nodes to color ports in the compound. I will fix it later.
