Ambient Occlusion (Tính Hấp Thụ Quang Xạ Môi Trường)

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.

Ghi chú

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

Render ‣ Ambient Occlusion

Khoảng Cách (Distance)

Distance of object that contributes to the ambient occlusion effect.

Hệ Số (Factor)

Blend factor for the ambient occlusion effect.

Độ Chính Xác trong Dò Tìm (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.

Pháp Tuyến Lệch (Bent Normals)

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

Nướng Hoạt Họa (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.
