I am working on the cannon below:
It is going to be used in a Christmas mobile game and is going to shoot presents. I want to make it have an animation where, when I shoot the present, it's a kind of cartoon-like animation where the present goes through it visibly. I asked this question already a few days ago, and actually made the animation, and it turned out just how I imagined. But using the lattice modifier didn't seem to work, because it cannot be used in Unity. Also, Alembic files are not supported by Android, nor iOs. So I need a different method, without the lattice modifier, to do something like this:
What could be the Unity compatible tools to achieve this effect?
