For example, let's say that for some reason a character has a body part like a bird beak/mouth that is only one image, and I want to move the upper or lower part independently using a mesh.
I split up the upper and lower half of the mouth with the appropriate vertices, and using weights I assign them to the appropriate bones. For some reason, even though the lower bones have 0% weight effect on the upper mesh vertices, they still affect them, and thus the desired effect can't be achieved. Is there a reason for this, or something I'm missing? I would love an example if possible.
Thank you!
