I actually had the mat pose editor crammed into my poser files zips. I just never knew what it did before! LOL But it worked like a charm> just one question though, In the tutorial given that works with the cr2 builder, it says to rename the pz2 into cr2. I don't understand the difference. But I tried it and when I did the cr2 extension, it didn't show at all in my poser files. but when I changed the extension back to pz2 it worked fine. is there a major difference in the 2 files?
