Dang. Just tried VizUP demo (exported Poser5 Woman from Poser 5 as VRML). Looked EXACTLY like what I needed. Fantastic interface: does the analysis ONCE, then can INSTANTLY switch between reductions by 10%, 20%, ... 90% at the push of a button. Reduction by 75% (to 25%; 44K polys => 11K polys) looked like just what I needed for animation performance in Poser. I REALLY like it that the vertices aren't MOVED, so that texture maps still work well - expect that there are INHERENTLY problems at texture seams when using any poly-reducer - and that would be true here as well. Just one FATAL FLAW: VizUP doesn't realize the body parts should stay welded together. So it creates polys that DON'T LINE UP between hip-abdomen-chest etc. WORKAROUND: Import OBJ P5NudeWoman geometry, Export VRML to VisUP. Now it CAN reduce - but no longer knows about the body parts, so they would have to be re-cut (in UVMapper or elsewhere). For me, not currently worth the $300 VisUP now costs.
