Bug: V-Ray Switch Material on V-Ray Decal - V-Ray GPU

[christian_schneider1]

I tried to use the V-Ray Switch Material on a V-Ray Decal and it does not produce correct results when using GPU. I even build a test scene and the issue remains.

this is how it should look like with the working opacity.
this is how it looks when a switch material is used.

CPU doesnt have the descriped problem.

Hello christian_schneider1 I have managed to reproduce the issue and have logged it into our system for further resolution [VC4D-2252]

Keep in mind that it does not occur if the renderer is CPU, if the Standard V-Ray Materials are used, if V-Ray Decal is not used. There are workarounds to create what you aim for.
