@photex Multiple Render Targets. Basically draw to multiple render textures in the same pass. It was supposed to say "It renders a 2D lightfield as fourier coefficients in an MRT." Each pixel is a little light probe that encodes how light is moving through it using 5 values. Without MRTs it would take 5 separate passes to render it.
