Property Value

Type: Single
The jitter resolution. The jitter resolution is the number of noise texels per world space unit. The default value is 2048.

Remarks

This value is only used when jitter sampling is applied to filter shadow edges. Jitter sampling uses a noise pattern to choose which shadow map texels are sampled. This noise is stable in world space. The JitterResolution defines the size of the jitter pattern relative to the world. If the jitter resolution is too high, then the noise becomes visually unstable when the camera moves (because there are too many noise pixels per screen pixel). Low jitter resolutions can cause a coarse blocky noise patterns.
