Weird bone twirling

[KenH]

I've been having this problem a while now (v11t/11.1 alpha/11.1 betas) and written to all concerned but to no avail yet. I don't know where the fault is(AM or TSM2). Here it is:

 

Open the attached project.

Select either foot bone and move them.

Problem: The foot jumps to another position relative to your pointer.

 

OR

 

Select the hand bone and rotate it (works for all bones)

Problem: The bone will rotate out of control...not keeping pace with your pointer.

 

The thing is this doesn't happen if I put start a new chor.

I'm hoping I won't need to export the actions into a new chor as there are all sorts of constraints set up with other objects already(hands are constrained to barrel at one point)....it would be messy.

We've taken a look at this, and it looks like something that often happens when using constraints in A:M, and then animating on top of them. Grabbing the end points of bones in this situation tends to make them go haywire. Thankfully, there's an easy solution to this--just use the position or rotate manipulators instead.

 

Things are working fine in you're chor, because you haven't added any constraints to the bones you're animating there, and you have in the action.
