56:15cdawzrd if you wanted to see the lighting distort according to the spherical shape of the normal map, would that just be part of fixing the math in the section where you sample from the env map, or is there more to it?

1:04:37starchypancakes Could you contain all lighting information in a 5 byte bitmap: 0-255 Absorbance/reflectance scale for RGB, Alpha, and scattering? I want to try it but I feel really hesitant because you warned against non-32 bit aligned structs
