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.

Thank you, Manticor. I don't have any future plans for another addons.

Interesting conversation on Softimage list:
Did anyone just happen to notice cycles nodes on softimage includes SUBSTANCE DESIGNER MATCHING PORTS FOR SHADING? Meaning: import stuff from substance directly with cyNodes into SI. Deeeengg that's a time saver!

Huge update to Softimage if you ask me considering it's 2017 and .Sbrs *kind of is a standard now*....
and

wait...how was it possible to get a 2017 shader code from bsdf into Softimage? just add the renderer code necessary and voilá?

Say what?!!
(Thinking about those nodes to get Substance designer shaders into softimage could be possible via SYcles).
D00d!

Update - version 1.3. Download it here: https://ssoftadd.github.io/syclesPage.html

What's new:
1. Add support of OpenColorIO color profiles. By default Sycles contains profiles from Filmic Blender addon for Blender, but it is possible to use any other profiles (even downloaded from http://opencolorio.org/). How to use - lesson 20 in the manual.
2. Shaderballs preview for materials. How to use - lesson 21. Also there are some new shaderball models.
3. OSL-shaders support. It turns out that in Softimage is mush more convenient to use such external shaders. It automatically recognize files with *.osl extension and add it to RenderTree as usual shader nodes. Some library of osl-shaders can be download from here: https://github.com/sambler/osl-shaders

Frickin amazing. Till I can afford something like GPU cards and Redhsift licenses, I might actually jump onto using this.

Has anyone tried benchmarking this in Softimage? Against Mentalray? Arnold? Redshift?

Yep, totally, we should consider benchmarking this! A total Arnold / Substance vs SYcles /Substance would be a totally awesome video!!!
I think I need to gumroad this for a dollar. :)

Small update - version 1.3.1. Download here: https://ssoftadd.github.io/syclesPage.html
Or simply replace the file with the same name by this dll: https://ssoftadd.github.io/download/cyclesRenderer.dll

This update fix only error of the wrong caching of a pointiness attribute.

hi shekn,

really great integration of cycles...thank you.
tried myself before to integrate cycles in si but without success...
just dowloaded it an tried first installing in xsi 2013sp1 but not worked, then in 2015sp1 and it worked.
now testing ice strand rendering and everything works great. makes a lot of fun.
what about xsi-hair? is that possible to implement too?

concerning gpu rendering support, can you explain a little more why exactly this wont work in xsi?
would be really great to have this option...there are not sooo many great gpu path tracer for xsi out there...

also...

HDRMaster plugin demo

HDR Master is a part of the Cycles addon - Cycles render integration into Softimage.
And Kudos for what indeed seems like an excellent integration!

Thank you guys.

It seems I found a way to integrate Cycles GPU rendering. I will try to do it in the next update (whenever it will be). About XSI internal hairs, I think that it is possible to integrate it too.

:-o :-o :-o :-o :-o :-o

I have used Cycles in Blender and with my 6 gig card Gtx1060, compaired to my i7 I get a faster calculation by around x4 times. This is.. good news! I also have a new contract I can do in SI, so I will definately test this out.

Next update 1.4. Download here: https://ssoftadd.github.io/download/Sycles_1.4.xsiaddon

What's New:
1. Compiled with the version of Cycles from Blender 2.79. In particular, some render parameters have been added (and some have been removed). In most cases this is technical parameters.
2. Added denoising feature and Shadow Catcher property to polygonmesh object.
3. Standard XSI-hairs render support.
4. GPU rendering. The device for rendering can be specified on the Performance - Additional Settings - Device of the render parameters.
5. Two new tutorials on the manual (23 and 24) about how to render standard XSI-hairs and how to use Ray Visibility.

For testing GPU-rendering I used Nvidia card. I don't know how it will work on Radeon. So, if somebody can test Radeon - it will be great. But there are no guarantee that everything will be fine.
