Anisotropy not working on GPU

V-Ray V-Ray GPU Issues

Hi
Anisotropy on GPU is a new feature of Vray 3.2. Somehow this doesn’t work for me. I have duplicated your material settings from the official 3.2 video
https://www.youtube.com/watch?v=d\_fuhYzxZNc.

Works fine on cpu though. Is it a known bug or am I missing something?

It works fine over here. If you have a scene where it doesn’t, can you send to support@chaosgroup.com so that the support guys can look into it?

Best regards,
Vlado

hmm tried it on different scenes with no luck with Blinn material. I will send a simpified scene to you.

Found the bug. Anisotrophy doesn’t work when its part of a multisub material

Oh, good catch - will fix it.

Best regards,

Just to add up - it’s not working only if using “Map Channel” mode for the anisotropy, local axis mode is fine.

Nice..that worked Peter.

Vlado there is also a strange line from the Gradient Ramp with GPU. Compare cpu and gpu versions from this thread.
