Max 2016 + Vray 3.20.02

Using a VrayLight dome with a VrayHDRI texture. The “Affect Alpha” option doesn’t have any effect when rendering with VrayRT. Is this not supported in VrayRT ?

Any update on when alphas will be introduced in RT would be much appreciated. This is kinda of a pipeline killer right now.

Thanks!

This is not supported yet - we’ll make feature request about it and we will update this thread when it is implemented.
Thank you very much for your patience.

Its being long time but this has been finally fixed into the latest beta version of V-Ray Next.
