The more exposed the shadowed area is, the more indirect lighting it receives.
The reason anything inside the building shadow is visible at all is due to indirect lighting being scattered from other sunlit surfaces, eventually illuminating the shadowed areas. A building lit by the sun creates a drop shadow, which is the area that the direct light source cannot reach. Even though many older games already contain SSAO variants, swapping them out for MXAO is very simple and beneficial.Īmbient Lighting is all lighting that is not emitted by direct light sources. MXAO creates results on par with current-gen industry standard implementations and can vastly improve the realism and depth perception in games. It simulates the diffuse shadowing caused by the occlusion of ambient lighting. MXAO is a high-quality, high-performance implementation of Screen Space Ambient Occlusion (SSAO).
