Vray Matte object

I know turn off alpha contribution for objects in VRay, Would it be possible to have a matte objects alpha mask or occlude objects that the are masking, like “matte alpha” check box :slight_smile:
I think the blur Matte Mtl free plugin from Blur studios does that, and it does help with compositing.

I bet it already in VRay and i just have not found it yet eh!

set alpha contribution to -1

Thanks for the tip egz i will go try it out. :smile:
