Edit: one question, how do I update it then I change resolution? My guess is that I need to resize the camDown[i]->bmap, but am I correct? If so, then I need to think of a way to changing the size of it's bmap, rather than recreating it over and over again (I guess).

Edit2: also, how do I remove it from the chain if I need to? Removing everything created (material, views and their bmaps) results to some very strange but interesting results I tried to make it work with pp_add and pp_remove, but no luck, since I'm too noob related to shader things
