Just to report a bug in Vray 1.5 SP3 that would be nice to correct:
A simple glass material (refract white for example with affect “color +alpha” or “all channel”) will render correctly the alpha BUT won’t render correctly the alpha when inside a shell material (although it’s correctly set as Render)
Well i mean the Shell material type yes
(which is indeed generated from Render to texture but can also be made manually)
Shell material is usefull for us because it allows us to render a realtime scene with Vray and still have this realtime scene with standard materials applied (in the baked slot)
