I saw something in a recent update about doing stuff with FILT by setting it's TMP value, only when I tried to find more about it in the Wiki there was nothing there. Help?
Setting its tmp to 1 will filter photons, only letting photons with similar colors to pass through. Making its tmp 2 will add that color to the photon's color, not overwriting it. Setting its tmp to 3 will subtract color from the photons, without just overwriting their color. Maybe I should add this to the wiki.
