Ambient Occlusion Pass Affected by Lighting


#1

Does anyone know of a good technique to render out an Ambient Occlusion pass that is affected by lighting. For example a bright sunlight spot would have less AO than in the shadows or less light areas. So far I can only seem to render out a straight pass which lights don’t affect. This can look slighting wrong in a composite. Is this a texturing technique perhaps. I’m using V-ray but I guess this is applicable to all.

I’ve just cracked how to render AO in reflections, now this I can’t work out! Thanks

I think it’s discussed in this dvd http://www.thegnomonworkshop.com/store/product/431/Multi-Pass-Compositing#.Vu6MsiJRHTY
I don’t remember off-hand all ins and outs, but you add direct lighting over occlustion.

Hey thanks, I guess that would make sense overlaying a direct lighting pass. I’ll check that course, really helpful cheers

This is what i normally do in maya for a light based AO.
