As for the multiple files issue, there are a couple of ways around it; If you import a single mesh with named polygon groups, you can "attach" these groups to a bone of the same name in the Setup Room. You can also pre-create your joint hierarchy by creating a Phi File -- this is a simple text file listing the joint hierarchy and rotation order -- and import that into Poser to rough in the bone structure. If you prefer to work in the main window/heirarchy editor, you can use the Grouping Tool to "spawn props"; the latter exercise will create one object in your workspace for every group that was in the imported mesh. I see a couple of elements in your robo-skeleton that may need more tricky rigging. When you get the rest of it basically running, look into ERC and the "point at" function for possibilities on those hydraulic cylinder-looking things on the back of the legs. If you are really serious about rigging new Poser creatures, I would recommend getting your hands on a copy of BL Render's book. Unless they make radical changes to the code base in Poser 7 (unlikely), most of that book will continue to be applicable for quite a long time to come. ("Secrets of Figure Creation with Poser 5")
