We are fortunate to have P3DO Explorer. There is a plugin to convert rsr to png and png to rsr. At this point, I have both Poser Pro Pack and Poser 4.03 on my computer. They are on separate hard drives. The Poser 4.03 installation is minimal. That allows me to do testing and some prep work for regular Poser users?! Which gives us an rsr if I share something.
