Wow, you guys are full of wisdom and knowledge here. Now let's see if my feeble mind can keep track: 1.) PPP will automatically convert library rsr's to png once you load that library "folder." 2.) rsr's in libraries won't do any damage, but you can safely delete them? 3.) Every PPP user had Poser 4 first, then upgraded over that. This is where I'm a bit uncertain: 4.) The Geometry rsr's from Poser are replaced by those generated by PPP? Or something like that? 5.) This one has me totally confused. What is it about converting bums back to jpgs? Youch. I'm reinstalling everything from scratch (once again). That means I won't have converted any bum.jpgs. I suppose that is an advantage?! Ron
