After several hours of searching through posts, I'm still confused on this one.
We have a scene that is taking forever to render and we are trying to render objects in passes. I've figured out how to render out the passes but I'm having a problem getting the reflections to show up when Comping in PS. See images below.
This is the rendered image of my test scene. Note the reflections on the plane.
Here is the plane rendered with the box & sphere turned off
Here I've set the vray props.. for the plane to: Matte object=checked, Alpha contribution=-1, Shadows=checked, Affect alpha=checked.
The box and sphere render seperatly and you can just barely make out the reflections. (They are tough to see in this small image but trust me they are there.)
Here's the Alpha. The shadows are there but not the reflections. (should they be?)
I Brought the box-sphere image in as a layer on top of the plane image. at 1st I tried creating a mask with the box-sphere alpha which worked except for the lack of reflections. (makes sense since the reflections are not in the alpha)
I then went through all the PS(CS2) blending modes and none of them would work with the two layers.
Should I be using another prog for comping? (I read in one post that combustion has an "ADD" blending mode.
Do I need to take this further and output Gbuffer layers vs just rendering in passes?
Any tips / pointers would be apprecieated.
Thank you
