关于切线空间到世界空间的转换：Common.ush文件中：
/** Transforms a vector from tangent space to world space */
MaterialFloat3 TransformTangentVectorToWorld(MaterialFloat3x3 TangentToWorld, MaterialFloat3 InTangentVector)
{
// Transform directly to world space
// The vector transform is optimized for this case, only one vector-matrix multiply is needed
return mul(InTangentVector, TangentToWorld);
}
在ShadingModelsMaterial.ush文件中：
#if MATERIAL_TANGENTSPACENORMAL float3 tempnormal = normalize(TransformTangentVectorToWorld( MaterialParameters.TangentToWorld, ClearCoatBottomNormal0(MaterialParameters) )); …… #endif
