shedofjoy - yes you can turn on AO for a light, however there are a couple of issues with doing this.... 1) If you have multiple lights in your scene, the AO given from the light you add AO to will be proportioned to the intensity of the light - so if the light is at 50%, the AO will be at 50% 2) Different materials will require difference raybias' and maxlens - and with light based AO - you are tied to useing just one raybias and maxlen. 3) More often than not, you only want AO on a subset of the materials in the scene. For example, if V3's hand is on her hip, IMO, it looks better with you only have AO on the SkinHip (and not include it on SkinHand). Similarly with clothing - better to have the AO only on skin, and not the clothing. I also don't like have AO on walls or furniture. Using light based AO doesn't give you that flexibility.
