Using Widget To Rotate Skeleton Branch/Limb // Bugs

I'm not certain whether the following behavior is a bug or by design. But it certainly caught me off-guard, so I figure I'll ask about it.


If I have the Shape Skeleton tool selected then I click the Dynapose tool to do some posing, all "direct" manipulations of the skeleton (as far as I can tell), work fine. I can click on bones and pose them as I wish. But if I instead click on a joint with the intention of using the manipulation widget to rotate a whole branch or limb (as shown in one of the manual videos), clicking and dragging on one of the widget's rotation arcs does not cause the branch/limb to rotate. (I can usually see that the joint itself rotates in place -- and various fields in the panel stack "try" to change -- but the bones attached to the joint stay where they are.) It appears that to get the widget to work properly, I have to explicitly deselect the Shape Skeleton tool (leaving the Dynapose tool selected by itself).


Is this behavior intended? That is, are we supposed to have to explicitly deselect the Shape Skeleton tool before using the manipulation widget with the Dynapose tool, but not if we are going to click on the bones directly? Does it enable me to accompish some task that I wouldn't be able to accomplish if the Shape Skeleton tool were just automatically deselected whenever I clicked on the Dynapose tool? (Now that I understand what's going on, I guess it's not a big deal. But it sure did take me a while to realize what was happening.)

Um, sounds like the joint limits are working against you. Check the joint limits on the joint you're trying to manipulate. Joint limits affect both IK and dynapose.

Another good tip is to rotate the joints in object coordinate mode when setting up your skeleton so that you can use the axes of the widget to align the z-direction for the joint to the bone or angle you want it to line up with.
