I’m the new guy in unity, i try to make some special animation for humanoid bone, is there anyway to do that with unity or i must use some other tool to do that?
As long as the character is rigged in a third party software with a bone system (Cinema 4D, maya, 3Ds max, …) the bones are just moving transforms. You could animate it with the animation window, but I highly recommend you doing this is the software itself.
It could be used if a character’s head has to follow the mouse. We just alter the rotation of the bone which controls the head, and make it face towards the mouse’s world position.
