I am not exactly using Poser with MB, just the meshes. Poser is an awesome mesh resource. But I could not use it as a professional animation tool with wasting time unnecessarily fixing quirks in motion. Basically, you must learn a program like 3dsMax, which I did. Then master rigging in Physique . There are other mesh deformers like the Skin Modifier, & BonesPro, but save yourself some trouble & choose Physique, which attaches the mesh to the bone/skeleton, which you do the actual animation onto. Motionbuilder is an incredible program. Max's renderer is way better than Poser's, way faster, & the Vray rendering plugin better yet. Not only can you actually use Global Illumination for animations in Vray, but it permits a network to render together on a single frame. If you are serious, email me at angrymobb@comcast.net for more info.
