Cycles for Softimage

AO Pass render test

That looks better than the previous errors. What was it?

EDIT : The AO Shader is still broken. This is just AO PASS in the render manager.

Cycles 1.7 - Edge Render Test

[Shekn]

Update 1.7.1 with ao-fix (and some other small changes). Download here: https://ssoftadd.github.io/download/Syc ... 1.xsiaddon

After some investigations it turns out that incorrect rendering of the ao node is a known issue (https://developer.blender.org/T55563). As I understand, there are no universal solution for it, because this bug related to the version of compiler, used for building Blender and Cycles render. It appears only on some processors and in versions, compiled with vc12. With vc14 no bugs, and now Blender and Cycles official supports only vc14 compiler. But plugins for Softimage must be compiled with vc12 only. In any case, there are three posibilities to render correct result of ao-node:
1. Switch to OSl shading system.
2. Use only GPU for rendering.
3 (the best method). Turn off AVX2 parameter in Preference tab of the render properties. This is a technical parameter and I don't really know what it does (something with processor instructions).

Also ao node is more universal now. It returns color or float factor of the ambient occlusion an can be used in render tree for creating some effects on edges and cavities of objects. For rendering classical ao-pass, the color output of the ao node should be connected to the color port of the emission node.

Thanks a lot for this update

Very much appreciated Phil. This is clean as it can be. With Redshift stopping dry without AI denoiser the only viable choice now it´s CYCLES with OptiX Denoiser. Quite impressive.
I´m pushing the SOFTIMAGE XSI MOD theme onto official Blender Build. Get here and vote me up: https://devtalk.blender.org/t/call-for- ... es/3174/50
Thanks!

Hey David
Hope this theme will be very close as Softimage
All the best

I work more and more with Cycles for SI and it is very great

[wireframex]

IES photometric files into Cycles for SI will be very cool

I found this for blender https://blenderartists.org/t/ies-lamps ... les/560285

What about cryptomatte? Can it be ported to Sycles? bevel node is working for what I saw on your post. Thanks for putting all this effort for the community!

Next update - version 1.7.2. Download here: https://ssoftadd.github.io/download/Syc ... 2.xsiaddon

This update is primary for bug fixes. What fixed:
1. Bugs in uv-coordinates on symmetrized objects and subdivided objects;
2. Bug about normals calculation on mesh with envelop deformation;
3. Some other small bugs;
4. Some improvements. For example, now vertex color can be rendered directly without any convert process by ICE. Simply add to the shader attribute node with the name of the vertex color cluster, and it will be rendered correctly.

What new:
1. IES Texture node for using ies-files;
2. Previously subdivided surfaces ignore hard-edges. Now hard-edges and edges with non-zero creases subdivides correctly;
3. Change UI in a Cycles Mesh Property. There are too many parameters in this property, and so I divide it into several tabs. The same done for Pointcloud Property.

Cryptomate I will try to implement later.

Thank you very much for this update

Oh MAN! reading CAV attributes like Cycles!? W00H00!! Man, you´re the hero of this movie!

Example of using IESTexture node. Sometimes it needs to rotate light source or change it strength.

[sirdavid32]

so fantastic!! Even nicer than native!
Yeah! Emissive rules.
Feels like second nature to work like this in softimage!
Thank you so much for this.
Is cryptomatte available yet?

Thanks a lot, I didn't rotate the light thats why it doesnt work at first
Real pleasure to continue with SI

[Shekn]

Rotations needs because potentially there is a difference between local coordinates of Softimage objects and coordinates, used for storing data inside *.ies file.
