Opening a Sphere Mesh I'm planning an animation, and one of the creatures is going to basically have a mouth. It'll be roughly spherical, but... unlike most of the ones you are thinking of, I want the opening to 'bend open' the sphere.

Okay, I'm not sure that's how I'd describe it, but... think Pac-man, then think THIS:

That 'thing/eldritch horror' is known as Chuxtoepose. It's from this game and I want to make that magnificent jaw by cutting into a UV Sphere. Is this doable, and how?

Thanks, Nefer
Create a sphere, move the pivot point to the point where you want the mouth to open.



Duplicate. On one sphere delete the top half. On the other delete the lower half.


Animate both objects by rotating them in opposite directions.



Optionally create a cycle by extrapolating the keyframes in the curve editor (Channel->Extrapolate->Make cyclic).

Add an empty and parent both hemispheres to it.

To move the object just move the empty.
