Hey you all!!! ( and Merry Christmas )

I have a question about the option: "Animate"-"Skeleton"-"Move joint/branch" because I
cant make it work proberly...

I am doing a simple (2d or 3d)joint-setup, lets say an arm. Then I want to move the "albow"-joint a little back so it fits my model...That work fine!!! but when I am trying to move the effecktor it flips back to the original position but keping the new lenght.
Also when I am hitting "undo" ( ctrl-z ) the bones does not change back to the original lenght and position....

Am I doing something wrong, or do I have the wrong idea about this tool..

Thanx

Erik

You are doing the right thing. But when you are making the setup, don't move the skeletion with the end effector unless you have a UP-Vector constraint to control the movement.
That is why the arm is flipping. I personaly never use the "move joint", I use the property page and the lenght slider (and FK rotations to match the angle).

best regards

Hi Erik & Stefan - I posted a response on the xsibase forum here : http://www.xsibase.com/cgi-bin/yabb/YaBB.cgi?board=animation;action=display;num=1040589714

Basically, there seems to be a bug I believe in move joint/branch (which is probably my fault - apologies) in that it doesn't correctly propogate the home angle inheritance across the whole chain, but the fix I post at above link seems to make things work OK. Let me know how you get on,
