Vray Displacement with Decal - Cosmos objects are black

[martin_weiss]

Hi,

Using a Decal with a Displacement makes all Cosmos items black in GPU render. All shaders of them are alright and presented.
No problem with CPU.
Win 10, Vray 6 for Maya 2023.3

Hi,
The issue is with VRayDecal with a combination of VRayProxy and displacement in the VRayDecal and using V-Ray GPU.
If all of these factors are present the VRayProxy renders completely black.
I have reported the issue to the developers and logged it in our bug tracking system under VMAYA-11969
Thank you for your cooperation.
