GPU Production Render - Material ID not working

Have noticed it renders a blank black render layer. Works when i change it to CPU Rendering.

Currently running, VRay for Maya 34006 with Autodesk Maya 2015.

Thanks!

The material ID render element is not yet fully supported on GPU. Here’s a list of what we currently support: Chaos Docs

Thanks for the reply… Didn’t notice the footprint notes at the bottom of the page.
