...

The bias will affect the falloff of the curvature and will always be linear, decreasing with the distance from the shaded point to the sampled point.

The closer to 0.0, only points closest to the shading point will contribute.

...

The closer to 1.0, the more all sampled points will contribute. At exactly 1.0 sampled points at all distance distances will contribute equally.

Falloff

Falloff can be used to control the softness of the occlusion effect.

Max Distance

The max distance at which objects may occlude. Zero is infinite (all objects occlude).

Direction

Trace rays in the direction of the surface normal (outside), inverse to the normal (inside), or in both directions.

Bias Normal

Add a directional bias to the normal vector. Values must be specified in world space.

Output Type

Set to "Concave", only concave curvature will be output. 

Set to "Convex", only convex curvature will be output.

"Both" will show both convex and concave curvature.

Trace Set

Assigning a trace set will mean curvature will only be tested against objects within that trace set.
