Transparency Cryptomatte Vray for 3dsmax #75

Closed Tylox81 closed 6 years ago

Tylox81 commented 6 years ago

Hi guys,

i'm working on 3dsmax and vray and i can't figure it out how to enable transparency in cryptomatte. For example, i create a box with glass material, create some teapots behind with vray materials, and render it, the crypto doesn't see what's behind the glass !!! Some one has an idea ?

Regards.

I would ask Chaos Group support for more accurate answers, but according to the docs, VRay cannot be propagated through reflections or refractions.

You need to go to your glass material, and in the refraction section, set the parameter "Affect channels" to "All channels". This will propagate the Cryptomatte through the refractive material.
