Tutorial which describes the new 'Ambient Occlusion' method. This method is basically rendering out an occlusion pass(which is a grayscale or a tinted image based on environment map) and then overlaying this image over a flat lit diffuse pass(achieved by ambient lighting, I'll describe it later) to represent the shadowing caused by the environment.

This is great but is there a way you could automate the compositing process in photoshop per-frame.


This is the only downside that I can see right now as compasiting a 200 frame animation by hand would be a real pain

Hi,

that's what compositing apps (after effects/combustion/shake etc.) are for - if you've got access to Premiere that should do as well, as it supports the transfer modes for the footage layers.

There may be some free compositing apps as well - worth a look anyway.

Photshop can handle the comp'ing through the use of 'Actions' and Batch processing

Know the name of any of the free ones?
