as soon as i fix a showstopper bug... if there are enough bright things on screen, it simply blacks out. i'd wager that a buffer somewhere at a point decides to scream and says **** you.
also, disabling the hud while using the bloomy shader, results in the same effect. (this applies to all three postprocessing codes, Hery's, the mix of hery's and the bloomer, and the bloomer only)
also, hery's code seems ok, so its probably the additional framebuffer that kills the hud disableage. not 100% sure on this one, someone more experienced with OGL might want to check.
