float SceneEngine::ShadowProjectionDesc::_depthBiasClamp

single sided depth bias

float SceneEngine::ShadowProjectionDesc::_dsDepthBiasClamp

Double sided depth bias This is useful when flipping the culling mode during shadow gen. In this case single sided geometry doesn't cause acne (so we can have very small bias values). But double sided geometry still gets acne, so needs a larger bias!

int SceneEngine::ShadowProjectionDesc::_dsRasterDepthBias

Double sided depth bias This is useful when flipping the culling mode during shadow gen. In this case single sided geometry doesn't cause acne (so we can have very small bias values). But double sided geometry still gets acne, so needs a larger bias!
