This macro takes a Fg inputs Alpha and the luminance and extracts the highlights and shadows then uses the background to wrap light in the highlights and dark colors in the shadows, there is also an advanced button which allows you to add color to the shadows and highlights. Edit: I made a couple of changes to the Lighwrap. 1) I took out the final switch matte, it was giving me weird premultiplication, and i defualted the UI file to 1 and 0's for the softness and tolerance sliders
