Shadow Map Size
Controls the size, in pixels, of one side of the shadow map. Select from a
range of values between 64 and 4096. The larger the map size, the more
accurate the shadows, but the longer it takes to render them.
Shadow Softness
Controls the softness or fuzziness of shadow-mapped shadows. The value
you enter represents the number of pixels at the edge of the shadow that
are blended into the underlying image. The value can range from 1 to 10,
but usually values from 2 to 4 give the best results.
Shadow Volumes/Ray Traced Shadows
Produces volumetric shadows (Photo Real renderer) and raytraced shadows
(Raytrace renderer) for this light. Shadow maps are not available, but the
shadow map size and softness settings are retained.
