Actually. I was the person who discovered the problem. The problem stems from custom geometry being placed inside the .cr2 files by Poser3&4 when you use the group tool. Joe Grover from CL took the explanation one step farther and explained that to fix it. Just delete the empty g lines from the .obj files. What's happening in layman's terms is: In the ProPack. The custom geometry that's located in the .cr2 files is fighting with the .obj files that the .cr2 files point to. So to stop them from fighting. Open the .obj files in a word editor type program. And delete any lines that start with G and have nothing after them. Now to be honest. This is a real Pain in the Butt. Because those files are long. And it takes a lot of work to get rid of those pesky g lines. CL will be releasing a patch that will fix this problem as well as some other problems any day now. ScottA
