Is there any way to read/write joint data through python? I want to move the joint centers  with a script. I saw something that looks like one could read weight maps, but not write, and for joints the text search didnt hit much in the manual :/.

Thanks!

There is SetOrigin(x,y,z) and SetEndPoint(x,y,z)

Alternatively you could use Python to write and apply a pose file that will do the trick.

parmX=actor.Parameter("xOffset") parmY=actor.Parameter("yOffset") parmZ=actor.Parameter("zOffset") parmX.SetValue(myNewValue) ...

Aaaah super! Thanks so much.

And even one more question: Can one morph the core geometry? (Not make a morph target, but the .OBJ the figure refers to?)

So if you have a figure where all joint zones are converted to weight maps, then one could morph core geometry and joint centers on-the-fly to adapt shape and rig?

You can set individual vertex locations with:

SetX(value)
SetY(value)
SetZ(value)

So yes you can.

If you are getting serious about creating Python scripts for Poser you may find this publication of interest.

I was able to gather some python experience, thanks in any case Phil. What I already did was to make the posed-morph-loader, and now I think of exporting core .OBJ files with the joint centers contained in them as stand-alone-vertices so I can also just move them in an external modeller, and not having to worry about the joint-influence-zones. In my  understanding the use of vert maps locks the influence values to the vertices, and thus one can move them around in a modeller, without destroying the rig entirely.

E.g. I wanted to "blend" a weight-mapped V4 to a weight-mapped M4 and see what happens. Genesis for the poor, so to say.

As scaling seems to have some odd effects on bending in general, I thought scaling could be replaced by morphing the core geometry along with move of joint centers and using weightmaps.
