I would suggest rendering two copies of the image, one with aa and the other
without, both on a black background. Then, write a filter to take the edge
of one and paste it on the other.
(btw, followups in p.general)

Thx i was thinking to do that...but with a 352 frames animation of a
sprite (32 headings)
it can be very much work...both for the rendered and the "filter" (ie me
:) )
Maybe they (autors) will think of this feature in next version...i
hope...for games sake
btw, what is p.general ?
(i assume is povray.general newsgoup ...but i dont see it on my
threads... )
Thx anyway...
