Tweening or Animating

[Kelly]

Does anyone have any knowledge on how to use the tweening tool properly? I can't figure out what you do to apply the changes made within a step. I am trying to 'animate' an object, specifically a tongue, to make it move similar to the way a real tongue moves (up, down, side to side). I am open to all advice and ideas! Thanks!

The tweening tool was developed for an orthodontic workflow.
There's a start setup and an end setup and tweening generates the steps between start and end. The single objects are identical. There's no morphing.

So tweening might not be the tool for your purpose.

My suggestion:

1) duplicate the tongue
2) draw a curve like a spine through the tongue (intersect two sketches might be the best way)
3) select slice deform with curve
4) make the changes you like

Good luck!
