PML is a must have.I was cut down to size a bit, when I realized that it cannot replace a good rigging.I did tons of JCMs for Miki2 and they work fine untill the moment I try to combine her fixed poses.I mean I fixed "arms up" and "arms front" .But when posing "arms up and front" ,I had those ugly joint creases again . If you would like to create an animation, you are forced to create lots of keyframes and fix each of them seperatly with the PML tool.To point it out clearly : the problem is the Poser rigging not PML .
