Maya Displacement Shader IPR not updated

[sean_willis]

Hello!
I'm working on expressing displacement using Maya-native nodes (DisplacmentShader node plugged into the Shading Group.)
But I'm hitting a limitation in the V-Ray IPR not updating when shading parameters change.

Vray object properties will update displacement interactively, but DisplacementShader will not.

I'm using V-Ray 6 for Maya hotfix 1 in Maya 2022.

Thanks.
Let me know if you would like a repro scene.

Which parameters are you referring to? And is there a reason to use Maya's native displacement shader over V-Ray's?

For example, If you modify a color correct node to adjust the pixel value levels of a texture driving displacement in the shader. It does not update in IPR. But the same displacement nodes applied via Maya Sets does properly evaluate the updated shading graph.

I'm building a shading pipeline and am supporting both methods. I just happened to notice that IPR does not refresh when testing.

I see. The issue seems to be fixed in the internal nightlies. It should eventually be pushed into the stables.
