Cycles for Softimage

Plugins linking to this thread: (hide)

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.

Hi shekn,

Do you think to update HDRMaster soon ?
Thanks
Phil

Thank you ^:)^ ..

Ok. :)

About HDRMaster. I think about it, but if make update, then it should fix some other problems. For example, when it fills the library with hdr maps, then it spams jpg-s to the directory with hdr files. It's not ok. It will be better to store these secondary images in different directory or may be even in the database. Also it will be helpful to add support of the other renderers: MentalRay, Arnold or my other integrations (ospRay and LuxCore). It's possible, but requires some time.

Ok don't worry
It will be ready when it will be ready :)

About logging mesh names. You are right, I will fix it in the next update.

After a long time I have to do a job that includes a render. I'm trying to use cycles and I noticed a few problems:
The first is the disappearance of the tiles in the options (blender 3.4 has them), and every test I have to wait for it to complete the whole frame.
The ideal is that they existed and started from the center in a spiral, but I don't know if this is feasible.

Second problem, the render must perhaps be very large in size (it will have to be printed), and doing a quick test up to about 8000px it works, then it crashes (I have a GTX 1070 with 8gb of ram), it could also be a settings problem that I do not know.

These are two slightly different issues. Tiling rendering option is hidden in UI of the Sycles, because there are some problems with it. I can not properly setup this mode. I set all parameters in the same way as in Blender sources, but my render is crashes. So, it requires more investigations. In theory this tiling mode should help to render big images.

But, I tried to render 16k width image in built-in MentalRay, ant it crashed. I think that the reason not on the render engine, but in Softimage. It allocates the frame buffer for output to the screen, and if it overflow the gpu memory, then it crashes. All successfully rendered in the batch mode. MenalRay image with 16k output result and also Sycles image with the same size. In batch mode all works with cpu or gpu render devices.

Okay, thanks for the reply.
Tile rendering is very convenient for scene setup, when there is a need to calibrate the various materials. :)
Ok for the batch render, I've used it a lot in the past, if I remember correctly I still have a tool that helps in its creation ( RenderQ if I remember correctly). :D

Im having constant crashes on rendering Strands. Just a simple basic emission > generate strand trails and render causes softimage to crash
anyone experienced this?

I just tried. It doesn't crash for me. GTX 1070 and installation without DLL change.

I checked, and for me strands and, in particular, strand trails are working without any errors.
