RedPhantom, thank you for your reply.  I have brought my Runtime into P13, I have it on an external  hard drive because I have so much Poser stuff I have bought since 2010 when I started in Poser 7 my computer will not handle it all.  I have figured out how to bring the material from my runtime into the material room & change the materials but I can't figure out how to get to the many materials that I bought that didn't come in a runtime that I have stored in a file in my documents. Do I have to put them in my runtime & how do I do that?
