objects with low alpha appear black over other obj
Jan 21st, 2008, 10:12pm  
I've noticed that objects with very low alpha values render as black over objects underneath. This is not usually a problem as calling background() clears them, however if combined with creating a motion blur effect, using a semi transparent rectangle overlay, the objects actually leave a trail over the window that won't go away, and eventually obscure the 3D view completely.

Is there a work around for this?

nevermind, i placed the blur code at the bottom of the draw function and everything's fine and dandy now.
