just adding a typical usecase for verhicles:
the front wheel is rotating along the y-axis, and also rotates when steering along the z-axis.
my caliper is only rotation along the z-axis when steering.
so it would be super simple if we could copy the wheelhandler-linked-bone to the caliper-bone via rotation…BUT only along a selected axis…in this case the z-axis. (for a noob like me this would be the intuitive workflow…but im happy zip figured out the driven-controller approach)
update:
driven-controller works, but driving the car in the viewport makes the caliper jump around to one other position, even though i only drive the z-axis and nothing else. right now both bones (wheelhandler-linked bone and caliper bone) are on the same level in the rig hierarchy…directly underneath the root-bone.
is there a better setup that is less jumpy?
