Vray GPU with Blend material not rendering

[kangoocarl1]

I am having to animate a blend in between 2 Vray materials (currently trying with the rayBlendMtl) and this does work fine with Vray Next but once switching to Vray Next GPU the material does only render as black (so does not render at all). In the "Supported Features List" of Vray/Chaosgroup the BlendMtl is marked as "compatible" for GPU but I cannot get it to work. Anybody know this issue - or know how to fix or maybe having another idea how to find a solution?(I am forced on GPU rendering for this project I am working on...).

Any answers highly appreciated- thank you!

Hello,

It's working here on a simple test. Could you share a simple scene with the material assigned to a plane ?

Best regards,

The problem here is that there is a Multi-Sub Mtl as a coat layer, which is not supported yet.
