I am asking this question because i don't understand the benefits of face off's OcclusionMaster. Yes i know it adds AO to renders but what's the difference to using his Python script than adding AO to a selected light? or adding to the material in the material room? I would have prefered to see an image using AO on a light and one using OcclusionMaster to see what the difference is, has anyone done this???

Getting old and still making "art" without soiling myself, now that's success.
