In Gem, does anyone know how pix_levels works. I just want to kill all the reds or greens in a video. I don't understand the floor/ceiling stuff.
if you want to just remove all the greens and reds in the video, why not texture it on something that has no red/green components (like a [square] with [color 0 0 1]) - default texturing does a per-channel multiplication with the underlying color (so if the the channel "red" is zero for the geo, than the you won't have any red-component in the displayed image either) if you want to burn CPU-cycles, you could also use [pix_gain] and set the gains to "0 0 1"
Also does anyone know how to do the screen effect, similar to add....?
i don't know what the "screen effect" is.
