gwhicks: I'd love to try your script. I'm interested in how you cycle through all of the figures and propes in a scene. I have cobbled together a script, based on published scripts by Ockham and Netherworks, which will overwrite an entire figure with a hardcoded material. But, like you said, Poser 5 Mac is pretty flaky. Two fields in the shaderNodes section don't overwrite properly (easily fixed by a search & replace in a text editor), and if I try to do two consecutive figures without reinitializing Python - whamo, major Poser crash. But still, it beats changing every single material one at a time. When I get this thing a little more stable, I'll be sure to post it.

rreynolds: I'll try the Grouping Tool approach tomorrow when my P5 gets finished rendering. Thanks.
