Dan's version costs money is the main difference. I'm not certain, but I seem to remember hearing $90. Hope I'm not wrong and get irate mails about it, but I remember being mildly shocked at the price. As to what it does, I couldn't say. You have to join the group to get v1.51, but it's easy and worth it. Lots of good info in the threads there. I also use it for MATs. Yeah, just delete all the junk. I never got into using that MatEditPose thingy. I like to see what's going on. If I have a few MATs to do for one figure, I build a basic file with all the junk removed, then make what I need from that, saving the new ones under different names. mac
