patience :)

I mapped and saved my prop (a simple one piece slab of skirt armor and saved it as a prop with parenting to the figure's hip). THe prop has no textures on it and is set to all white.

I opened the prop file in the programmer's file editor and removed all the following: geomCustom data (several hundred lines of vertex data looks like this:

v -0.139294 0.324937 -0.047996
vt 0.025000 0.293374

I then removed all the parameters below that, all the way down to the materials (in this case, just one).

This is what the final file looks like whyen reopened in a text editor, after being saved as a .pz2 (the forum won't let me indent - follow the format you see in your text editor for the proper indentation of each line)
