Quote - from William the Bloody...  Ummm...something about each core processing shadows randomly, or something.  So every frame the IDL is calculated somewhat differently, resulting in noise.  I don't imagine rendering in png would be a difference.  I'll try to set up something in the next few days and see if it's still a problem...maybe a SR fixed it.

That's a tough nut to crack. It's been discussed before elsewhere here right after Poser 8 was released. If there's a way to generate a photon map, you might be able to work around it. I don't think Poser has Final Gather either. Bigger programs need those features for architectural fly-throughs and you still may run into problems. One of the reasons Pixar stays away from GI and uses light sets, besides saving render time.

Here's a workaround for 3dsMax:

The only thing I could think might work for Poser would be using GI to make backgrounds, elements and foreground layers and then use soft lights to simulate GI for your characters, render either with the elements or render the character animation separately with alpha maps and composite. Might actually save render time. But you'd really have to plan out shots.
