Sets the index of the light's frame attributes data in the frame attribs buffer. This index is passed to the HnRenderDelegate::GetShadowPassFrameAttri

|fCosChi| < Pi/2

Calculate a half-precision low-quality approximation for the reciprocal of a value. For additional information on the approximation family of functio

A single operation to return the following: m = NaN := 1 m > 0 := 0 m <= 0 := 1 This function is useful when creating masks for branch-free logic.

Adds shader texture indexing to the cache and returns its identifier, for example: {0, 0, 0, 1, 1, 2} -> 0 {0, 1, 0, 1, 2, 2} -> 1

If possible, applies standard texture indexing to reduce the number of shader permutations, e.g.: StdTexIds TexIds0 TexArray StdTexArray
