It looks to be a little easier way to create clothing from a particular character, because you can create a character from selected groups (polygon). The grouping tool is icky. I think you'd be better off trying to make the clothes in another program and bringing them into PPP to bone. If you made groups from the Poser characters, you'd then have to morph them all around to make them look anything like clothing. It would be far easier to export the Poser meshes into something else and build clothes around them. Face masks and possibly gloves are about the only things the grouping tool would be useful for by way of clothing, and even then, I still think the tool is pretty hideous. I also thought I read somewhere that MAT and possibly BUM files are created more easily with Pro Pak, but could not find any references in the user guide pdf. Nope and nope. MAT files are an outside discovery not "officially supported" by CL. MAT files are made with outside programs, hacking up a .cr2 file with a text editor, or hand writing your own. It's not hard to do, but P4, PPP, and P5 have nothing to do with MAT file creation. PPP and P5 use .jpgs for bump maps, which keeps the files sizes reasonable. P4 has to convert .jpg files to .bum files which are bloated monsters. PPP and P5 can use .bum files but why waste the space?
