Hi folks.  
I have 100’s of plants in my scene as proxy’s.  
I need to create a clay render for client. I have added to render layer collection with material override, but this doest effect the proxy’s they still have full colour.  
Any ideas on how to get them as grey?

I presume the VRayProxies are legacy ones. Try converting them to the new VRayProxy node (V-Ray\>Tools\>Convert to new V-Ray Proxy node) and it should work.

EDIT: Actually it works on both types. Does it happen with a specific proxy? What V-Ray version are you utilizing? A scene would be lovely.

Ah, you’re using these Shader Overrides. They work differently for .vrmesh and .abc - Shader overrides for .vrmeshes override **by material;** Shader overrides for alembics override **by geometry**. I’ve already pinged the Documentation Team to update the docs since it is not written there. Simply using the regular hierarchy “Override Shader” seems like the easiest solution.
