Suppose we create a very basic surface and single-faced lighting.
Is there a way to obtain the matrix indicating light intensity on the surface patches for the current view? Alternatively is there a way to simply obtain the FaceColor attribute which is being applied to the individual patches on the surface (I assume that from subtracting this FaceColor from the unlit FaceColor, we can obtain intensity)?
