I'm modifying a body part of an existing Poser figure, intending to graft it onto a copy of the standard figure to make a weird creature. (It's a 6-legged cat, if you must know; any Honor Harrington fans here?) I've imported the modified object as a prop and have used the group tool to create groups for the new appendages, in preparation for spawning the props to assemble the thing. (N.B., I'm doing the grouping in the Pose Room, not the Setup Room... since I don't have a whole body yet. I intend to replace the figure's body part with my modified object, then go into the Setup Room to make bones for the extra legs.) However, when I click on "Create Perspective UVs" in the Group Tool window, Poser crashes. (Mac Type 2 error, a memory-related bug.) I'm using Poser Pro Pack on a Power Macinosh G4 dual processor 450, with 100 MB RAM assigned to Poser. So, what is this function supposed to do? I figured it was a basic UV mapper to produce a texture mapping template. No big deal, I can just use the UV Mapper utility when I'm done, but this would have saved a step.

It just creates a UVmap of whatever polygons are selected. It's mostly designed for making things like Tatoos. You select what polygons you want to be part of the new texture. Then create a UVmap for it so you can apply a separate texture to it. UVMapper works much better for this. Most people never use the one in Poser. I don't use MAC so I don't know why it's crashing on you. But I've heard people say to assign 180meg. to Poser to keep it from crashing. ScottA

Hm, I think the trouble may be some funkiness in my object. I tried 180 MB and it still crashed. I modeled it in Amapi and exported it in Lightwave format, since Amapi doesn't do obj format. I tried the same operation using a simple ball prop and it didn't crash. And, once I put my figure together and took it to the Setup Room, "Create Perspective UVs" didn't crash Poser. (It didn't seem to have any visible effect -- does it just mark that group as being able to accept a texture, which can then be assigned separately in the Materials dialog?) Well, I'll use UV Mapper anyway, and chalk this up to a case of "Doc, it hurts when I do this!" -- "Well, don't do that!" By the way, as far as memory goes, I ran a utility that kept tabs on Poser's memory usage. It would seem that in the course of performing operations (posing, rendering, etc.) the memory required fluctuates by 1 MB or less. Apparently, giving Poser more memory lets you load more (or more complicated) figures.

Creation of perspex UVs came up in a post last year - there's a basic tutorial in it: http://www.renderosity.com/messages.ez?Form.ShowMessage=118024 If you use Poser to convert an Amapi-made model to OBJ format, pull it into UV mapper and give it a UV template, you should find it possible to do perspex UV when you're back in Poser.
