Transformations

Does anyone know how to change a human or a humanoid to a animal or beast using a transformation process?

Hey Amonster your question doesn’t have any specifics. Animation? Rigging? FX? Morphing? 3D? 2D?
This could be as simple as a texture swap and a transition animation from standing to a hands/feet pose, though that wouldn’t have the desired result you’re probably looking to achieve.
Or the change could be ‘magically’ covered. Think Shrek - when Fiona changes to ogre/oger form. Sorry I don’t have a game reference.

When you give some specifics I’m sure some of the community will respond with some additional ideas.
