Property Value

The computed ambient occlusion is blurred using an edge-aware blur to avoid blurring over depth discontinuities. The sensitivity of the edge-aware blur is defined by EdgeSoftness. The value is the max allowed depth difference of two pixel in world space units. Pixels that closer than this threshold are blurred together; pixels which are farther apart are ignored.

Decrease the value to make edges crisper. Increase the value to reduce temporal flicker.
