Oh I get it. It’s like a control point on a curve. Thank you very much!
I have been using them when making a hand rig to make sure that the fingers (I’m using an ik target for the finger position because the hand is going to be standing on it’s fingers) point the correct direction and don’t flip over into unnatural orientations.
It is strange though because the pole target seems to be doing the opposite of what you said. I have the pole target but the chain points away from the pole target. Also, if you move the pole target along the length of the chain (X-axis) it does not ‘weight’ the chain like rotating the bones in it does which would be nice.
This post has been kind of mangled because I tried a couple things and they worked differently but I will try to assemble some data.
The two attached files fing_pole_target and pole_target are different. pole_target.blend is a demonstration file I put together expecting to get the same problem. I did but when I clear the bone roll angles it is fixed. However it is exactly the opposite with fing_pole target.blend which is part of the rig I am concerned with.
There are some notes and an animation in the demo file (pole_target.blend) that may be helpful.
