Hi all,
I am working in Motionbuilder.
I am trying to create an animation where a foot is pedaling the crank of a bicycle. There is a bone in the middle of the crank and another one for the foot. The foot while pedaling, moves around the crank in a circular motion in the Translate Y and Z axes (the X axis does not have any values). The crank only rotates in X-axis in its local space, as in reality.
Bone_Crank needs to get its rotation-X values from the translation-Y and Z values of the Bone_Foot.
The problem is visualized here:

Can I work this out using a Relation Constraint? I haven’t used this constraint in my work before so, I am still in the learning process. Can anyone help me create a math equation to get this please?
Any leads or suggestions for a start, will be greatly appreciated!
Thanks!
Peace.
