Check _Snail racing..._ in p.g for more info.
Anyone think they can reduce the render time with Fltr=1?
Watch linewraps in area_light and #default in posting.

The best of luck :) I was hoping someone would see a silly mistake in
my script but as you can see, it is POV having to work very hard with
the multiple textures.

Yes, spheres are faster but then merge{} is also slow :(
Did you see in p.g ?
<quote>
This is a merge of 400 spheres, each with their own texture, 400*300
64K. No photons, around 18 hours.

The blob would seem to be an ideal render farm scene.
