Occlusione Ambientale#

Ambient occlusion is computed using GTAO and applied to indirect lighting. The bent normal option will make the diffuse lighting come from only the least occluded direction.

Ambient occlusion can be rendered as a separate pass in the Render Layers panel.

Nota

This effect needs to be enabled for the Ambient Occlusion node to work.

Riferimento

Pannello:

Render ‣ Ambient Occlusion

Distance

Distance of object that contributes to the ambient occlusion effect.

Fattore

Blend factor for the ambient occlusion effect.

Trace Precision

Increases precision of the effect but introduces more noise and lowers the maximum trace distance. Increased precision also increases the performance cost. Lower precision will also miss occluders and lead to undershadowing.

Bent Normals

Compute the least occluded direction. This direction can be used to sample the diffuse irradiance in a more realistic way.

Bounce Approximation

An approximation to simulate light bounces giving less occlusion on brighter objects. It only takes into account the surface color and not its surroundings. This is not applied to the ambient occlusion pass.
