Apparently PPP doesn't automatically convert rsr's to png. I had the bright idea one day to do a search and destroy of all rsr's in my Library folder. Guess what? Many of my items had no "thumbs." That obviously meant there were no pngs to replace those rsr's. I just looked through my libraries, and many sections which came from either Poser 4.03 or PPP had no png files! The prudent thing to do would be to scan the libraries, and see which ones have no pngs to replace the rsrs. Then use p3do explorer's rsr to png converter, and then get rid of the rsrs. Yes, I'm aware that some MATs should be used for PPP, and others for Poser 4.03. Here is a screenshot I made to show which ones should be used for "regular" Poser. Ron
