Someone trying hard to avoid learning Max rigging (me) needs to:
Read helpers local rotate x value (helpers rotation is controlled by a look at controller)
Divide this number by say 6
Pipe the value into the local rotate x value of a joint.
Please post detailed how to… Or better yet, swing by and do it for me
Yes, expose transform is what you will want to read the value, then use the wire parameters (alt 5) or animation menu-wire parameters to connect the values and ad the / expression to the new joint.
