this doesn't help you if you have ProPack. g It makes PNG, not RSR. I save to library, I get nice PNG files. What I do is... render my item. save as TIFF. crop and resize image in Fireworks (or other image editing program, I like Fireworks as its dealing with PNG and alphas really well) Save as PNG. use PD3O Explorer to make an RSR out of the PNG. delete PNG. let Poser recreate the PNG file out of the RSR that P3DO Explorer created. then you end up with RSR and a much smaller PNG file.
