I rigged the hands on a character I’m working on similarly to the setup in “intro to character animation in blender”. It works great in the original setup, but when I import him into another file and don’t have him walked straight on the x axis the hands don’t work any more. They basically go to the fist pose for the hands and stay there. I’m using 2.46 (which was probably a dumb move) so not all the settings are the same, like the C Space is kind of a mystery for me. But I’ve tried all the setting and nothing corrected the problem.
Actually I think I figured it out. There were two problems that I changed. In the book the hand actuators are rotating through Z space (up and down) and I set mine to rotate through Y space (front to back). which worked fine until it turned, then it wasnt in the same space.
The other thing was I didnt set the hand actuators to Local (I think because the book said not to in the feet) but when I looked at the sample rig, it was turned on.
But changing those two things, made it work for me!
