MRT allows for rendering to multiple texture targets in the pixel shader, but I'm not sure how many targets that is. I'm currently using 3 render targets but I may need as much as 5 (though probably just 4).

There are the following preconditions 0<= mean <= 1 and 0 <= r,g,b <= 255 and r, g, b are unsigned chars so if I try to use the fact that >> 8 is like dividing by 256 and I use something like float mean = (float)(((r+b+g)/3) >> 8); this will al...
