Hey all, am I unapproachable or something?  I am totally available to answer questions on this, my area of expertise.

If you are going to slave your dependancies from a prop, than you're going to need an injection pose for the figure.  There's no reason you need to have a prop though, you can pick an arbitrary body part and load that up custom dials, save that character, and just use that as your base figure and the info will always be there.

PoseMagicPro Gen 4 works just as OP described and beyond.  Starter Poses and then individual controls beyond there.  The beauty of PMPG4 is that you can continue to customize PoseMagicProp by creating master/slave relationships on the prop itself.  For example, I can teach a new dial a starter pose, tweak that on PoseMagic, everything done on this prop because it's so complete and thorough that you will never need to change the PMPG4 Injection Pose.  Just Save the prop!

Making the injection pose is currently an  absolute bitch kitten.  Especially if you're kinda anal like me and want the injection pose to be clean of all non-functional information.  There's a japanese cr2 editor that kind of helps but leaves some stuff behind that you've got to manually delete from the pz2.

It took me a couple of weeks of unemployment to get PMPG4 up and running.

I'll be happy to answer any questions about the process.
