V-Ray forum + exporting alpha channel from V-Ray


Anybody knows how to get permission to add topics to v-ray chaos group forum? I registered but there’s no such an option. Chaos Group doesn’t reply to my questions so I’m kinda only-looking member.

Secondly: I’m using SketchUp + V-Ray 3.4 and trying to save a render with alpha channel. But that channel just won’t save. The file is not being created. Any other channel will save - RGB, ZDepth, Denioser etc. Have not idea what’s going on.
