Ambient Occlusion with V-Ray

and have partnered to bring you a one time exclusive training event for Architectural Visualization Artists. Featuring industry experts Brian Smith and Chris Bullen, each class includes 18 hours of intense instruction over 2 days.

This is a tutorial they put together and we give them credits and thanks for taking the time to give us an insight in Ambient Occlusion in Vray. 

Ambient Occlusion (AO) is the measure of how much of the sky is occluded, or blocked from view at any given point on a surface. An AO image is always grayscale and is often referred to as a dirt pass because it can be used to add a dirty look to what would otherwise be surfaces that are too perfectly clean to be realistic. It can also be used to add detail as well as depth to shadows.
