Converting clothing is half easy, and half bloody difficult. A simple exercise: start with Judy's combat trousers. Import the .obj file, and use the Grouping Tool to share the two buttock groups between thigh and hip. [Best to enlarge the hip first. Then, each side in turn, switch to the thigh group, add that side's buttock group, and then remove the hip group.] Export the .obj under a new name. Take a Posette set of pants. Edit the CR2 to change the file it points to. Save under new name. You now have a new item of clothing. Pass it through the setup room, this seemed to cure a couple of oddities. Now the not-easy part: fine-tuning in the Set-Up Room to get good posing without excessive poke-through. For Judy to Posette, it seems that Judy's back and belly are differently aligned. Without adjustment, the back of Posette's legs poke through. But getting something that will work for a character standing around, that's not terribly hard if you want loose clothing. Those combat pants don't cope will with extreme action poses. So far, I'm inclined to think that different grouping is one of the smaller problems. Somebody must have described it better, somewhere...
