Below: Benefit of using multiple layers on McGuire et. al.’s Scalable Ambient Obscurance (2012). Ambient Occlusion from both layers (top), only the first layer (middle) and only the second layer (bottom). The red box highlights an area where the second layer provided a very noticeable correction to an error in a single layer only approach.
