Link UpperArm rotation to Clavicle?
polycounter lvl 18
Im using 3DS Max's biped system for a quick rig for my current character.
I have been trying to get the rotation of the UpperArm bone linked to the rotation of the clavicle bone so that when the spine rotates forward, and the clavicle rotates with them, the upper arm should be "locked" to the same rotation in the X-axis instead of being independent and keeping their original rotation
I can sort of get this to work on two test box models by going into the Wire Parameters dialog and linking the child objects axis rotation to the parents but can't figure out how to do this with the Biped system - or inherit the rotation of the world axis. I am wanting the world rotation axis of the clavicle to be taken into account and not the local rotation as the clavicle bone doesn't actually rotate on it's X axis when the spine bends forward, but does get rotated in world space.
I have added a Euler XYZ controller to both bones but am not sure if this is the right way to go about it as this seems to link local axis rotation only.
Anyone know how to get this working? I am sure it should be fairly simple but haven't ever needed to do it in MAX before.
