-- [ Picked text/plain from multipart/alternative ] Well, I understand.. so if I want to add some noise and blurring (another shader) to the final image (after doing all the night vision overb righting stuff), instead of a second pass inside the same shader I would need to use another FB, is that correct? regards, newen
