How to do “Smear” Animation in TB Animate (Limited Animation/Stylized Animation)

How would you go about creating a Chuck Jones style transition between two poses in Toon Boom Animate? Would you put a pixel smear between two vector poses?

Nooo. I draw. It’s too easy. Just keep to the arc. (Well, it’s what I do, at least). I’ve tried a smear that goes beyond the final pose, trying to get some follow through. For me, that’s only worked on occasion.

Yea, just draw it. That’s the fun part.

What else in 2D animation could be more fun than DRAWING…? ;DI will quit 2D animation the day any other thing surpasses the drawing part!
