I am presuming I can drive the user fresnel with a ramp or a user defined alpha mix to control the amount of reflected light.
I dived inside the surface model and noted the fresnel VOP connected upto a host of switch nodes and that the float input fresnel seems to be the entry point for the surface model vop.
So can anyone explain the sort of data expected and what happens inside the surface model vop. A simple example would be great !
