Render elemants in photoshop comp

[stezza]

Ok lets say I have my white poly plane and red sphere floating above and I want to render out all the elements that make up the scene which is has one light casting shadows.

I create a..
GI pass
shadow pass
diffuse pass
light pass

Which goes at the bottom of the layers and upwards in PS

But layering them in PS does not seem to produce any where near the result if rendered from the VFB.
I have tried all the overlay types in the layers.
What is the common layer set-up for PS comp and Vray elements?
Also what is RAW referring to in the render elements?



Thanks for your help
