Hey, I have some issues when trying to use transform constraint.
The situation is as follows:
I have a head control bone to create a fake-3D head turn. It is is the target bone for 2 separate transform constraints, one for the eyes and one for the mouth. This way when I move around the control bone, the eyes and mouth can move in their own way for that fake-3D head turn. All these functions as expected.
I also have a aim bone for rotating the whole body in aiming and shooting animation. I give the head control bone another transform constraint with the target being the aim bone, so that it can look at where it is aiming.
However, when I use the aim bone to control the movement of head control bone, it only affects the eye bone via transform constraint, and the mouth bone is not moving correctly with the transform constraint. So when the character looks at a direction when aiming, its eyes follows but the mouth stays in the original place.
(you can see that after I type in the mix value for the transform constraint, the head control bone moves away from its original position along with the eye bone, but leaving the mouth bone behind)
However, the eyes and mouth literally use the same bone structure. It is really strange that this only affects the mouth bone.
Could you help me with this issue? Thanks!
