Hello,
I'm having a continued problem trying to use VRAY RTX or CUDA GPU mode (RTX 4090) to render a material with a opacity map. This is a simple vinyl logo applied to a wall or display panel. This renders as expected in CPU mode, where there are no shadows visible from the opacity map as it is sitting just off the surface:
Whereas a RTX render shows a faint shadow as if the opacity map is not being correctly read by the RTX engine:
At first I thought this might just be missing the opactiy entirely but offsetting the logo to one side shows the opacity is intact, it's just this logo rectangle plane is dropping a shadow on the surface behind it, which it shouldn't be. Shadow casting turned off, etc.
I believe this has only started happening in VRay 6 for me and was working as expected in VRay 5. However, I cannot go back and check to confirm. Any idea what's going on here?
Thank you for your help.
