Hi That is interesting. I was about to post a similar type of error... I created a very simple 3 grouped chain and called the middle group body. Did it via the .PHI file method, which placed a cr2 in the library ok. However, Poser 4.0.3 would always crash the Mac when I tried to load it. It appears Poser 4.0.3 was confusing the BODY with my Body group in the cr2 file, when trying to load it. Spent ages trying to suss out the problem. Why as it seems such an obvious clanger on my part, well Poser 3.0.1 worked ok with this. I also get: Cannot find the g type errors in Poser 4.0.3 when using the .PHI method where the files are named correctly and Poser 3.0.1 will load them no problem. Suggests there maybe a Poser 4.0.3 bug hidden in there somewhere. Perhaps should do a dos and donts on the PHI way... Take care
