I have a humanoid character and when I have the IK set up, it moves the chain correctly. The issue, however, is when I rotate the character's hand, his forearm does not rotate at all.
In contrast, when I'm using Unity's IK Rigging and setting up a multi-bone constraint, it works perfectly fine.
Just like in real life, when you rotate your wrist, it should rotate the forearm, no?
I don't think I'm doing anything wrong because in UMOTION video tutorial, the same behavior issue is seen. (see video at 8:43 mark:)
