Render Elements Appear as Black or Messed Up

[ben_roe]

Hello,

I am trying to achieve a render with the various scenes needed to edit in Photoshop, i.e. Material ID and Shadows etc...

However when Vray finishes rendering those elements appear as black, in some cases distorted. I have displayed example screenshots of the problem below as well as an image of the model.

I have tried randomizing ID colours, I have tried rendering only with CPU.

Please help as this is driving me crazy and setting me back a few weeks!

Thanks
Ben

Hi guys,

Apologies for the delay.

Can you let me know if you are using Swarm or are you rendering locally? Is this happening with every project, or just a particular one?
What are the exact V-Ray for Rhino versions used?

Any details regarding CPU/GPU/GPU drivers would also be appreciated.
