Value > MAXWrapper > Shadow > ShadowMap |
Controls the shadow map bias - the distance from the shadowing surface to the shadow.
When set to true, the Map bias is taken as world units. When false (relative), the bias is calculated relative to the scene size.
When True, backfaces are not ignored when calculating shadows. Objects seen from the inside are not lit by lights from the outside. This costs a bit more render time.
When False, backfaces are ignored. Rendering is quicker, but outside lights illuminate object interiors.
