Render Elements behind Refractions

[Patrick_Coan]

How can I get render elements from objects behind refractive objects? In my current renders, the RGB pass looks nice, but the SSS is completely black. Hiding the refractive objects shows my SSS object. I tried setting the refractive Object to matte, affect alpha in VRay Object Properties, this doesn't seem to do it. RGB + Alpha doesn't seem to show the AOV's either.

I'm sure this issue has already been addressed! Thanks for chiming in.

You should set the VRayMtl's refraction to affect "All channels" (VRayMtl> Refraction - advanced> Affect Channels).

Awesome thank you.
