Hi all, I’m rigging a character and I’m using many constraint in the rig, after finishing the rig I noticed a very weird problem…
whenever I try to parent an object to a bone using any method (standard parenting, childof constraint, copy location constraint, copy rotation constraint) when animating a bone, I get a delay in the animation by at least one frame for the child object!
This happens when I use any constraint on the child bone then use any object as a target for this constraint, then parent that object back to any bone in the armature.
I created a simple scene that demonstrates this problem…
as you can see in the scene I used StretchTo constraint on one bone, then parented the target back to another bone in the rig, now when you play the animation you should see that the object “Empty” is moving but the StretchTo constraint is delayed to move in frame 2 not frame 1 as it suppose to.
this doesn’t happen when I parent the target object to any other object except the armature!
is this is a known bug ? please help!
