reflect alpha

[vance3d]

I'd really like it if vray matte material had an option to reflect the alpha channels of objects in the scene.

I'm doing a lot of product lighting and when I set up a scene with cards and stuff for reflections I need to generate an alpha of the reflection as a second pass because sometimes I need to comp the render of a light background. You cant add or screen a layer over a white bkg. a reflected imbedded alpha channel would be great.

I definitely second this.
The alpha from refractions is a great feature, but strangely enough never made it to the reflection bit. This would ease up most of my composite work.

exactly!

the old max raytracer did this and it really came in handy. As I recall, it would also reflect material id's as well.
