Occlusion

Computes the occlusion around the shading point in the direction of the surface normal.

Samples

Controls the number of occlusion samples per shading point. Note that increasing this can slow rendering down dramatically.

Cone Angle

Controls the angle of the occlusion cone around the normal.

Trace Set

Controls which object set is traced.

Ray Length

Controls the length of the occlusion rays. Shorter rays produce tighter occlusions.
