VEX Blur Shadow shader

The blurshadow shader generates soft shadows by sending out multiple shadow rays.

The blurshadow shader generates soft shadows by sending out multiple shadow rays.

Filtered shadows evaluate the occluding objects surface to compute the opacity. Thus, filtered shadows allow for transparent shadows. Fast shadows assume that all occluding objects are opaque.

The shadow bias can be used to prevent self shadowing of a surface The shadow intensity is a scale on the shadow intensity. Decreasing this value to zero will result in no shadows. At one, the shadow will occlude all light from the source.

The fog quality controls the oversampling when shadows are being evaluated from within a volume (fog) shader. This is a scale on the oversampling parameter.
