Actually.. you don't NEED the setup room to rig it. It eases the process, at least in some people's opinion (personally I avoid it at all costs) You can get Roy Riggs' Phi Builder and simply set up the hierachy in that, it works somewhat like Poser's Hierachy Editor, and when done you output a phi file, import that into Poser and you'll have your rigged thing. There are also some programs, personally I rely on Kattman's PWizard (here in the Marketplace - I think) - and some people like MarkDC's QuickConform. They both eases the setup and joint parameter thing greatly. (in short they'll take your grouped obj and output a working cr2 file. Some tweaking may be needed but depending on the complexity it's not all that much.

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
