I use Morpher, not bones, though you can use bones... its just a bear to edit the influences. What I really want is to be able to paint the weightmapping, instead of having to edit it almost vertex by vertex, and losing it all when I detach the skeleton. The only drawback is that morpher only lets you load one morph at a time. You need a lot more morphs for facial animation... I end up using Poser 5 to blend morphs and export as a facial target for Carrara. I don't know what Zmotion is truly going to be like, its supposed to import BVH motion files and let you import rigs and animations done in Motionbuilder. (and Poser)
