Hi all-
In maya under color/compositing there is a premultiply setting. Basically all it does is add a couple pixels to the edge of the image to be knocked out so there won't be a outline of the background once it is composited into another scene. My question is does Vray have anything like this?
I'm compositing plants into a scene and am trying to save on render time by using the sequence as the main plant pass and shadow pass. It's basically a white scene with plants and shadows. I use multiply to knock out the white and give me my shadow pass and then use the aplha to knock out the main plant render on top of that, except I get a white outline around my plant. One way to fix that would be to render the main pass with a green backround and the shadow pass on white but like I said before I'm trying to save on render time.
Any suggestions??? Thanks in advance
