GPU : vrayobject, mattes and vraymtl coat attribute.

V-Ray V-Ray for Maya Issues
1

Just a little issue, but thought i would post.

When using vrayobjectproperties, to create a matte with -1 Alpha contribution, theres the reflection slider which you can turn to zero to prevent it contributing to the matte. However this is ignored when you add the ‘coat’ attribute.

Works fine in cpu, but not gpu (cuda or rtx)

Thanks for the report. I’ve logged it (internal bug-tracker id: VGPU-5862) for developer investigation.
