How can I morph a flat plane to be a flat cirlce? So I'm making a 2d animation in blender, using the z space as layers, and the camera is in orthographic view.
I'm trying to morph a square plane to be a flat circle, but I have no idea how to even approach it.
The easiest way, in my opinion, is to use the 'Cast' modifier. Using a subdivided plane you can cast/warp an object from one shape, to another, preset shape:



Animating the 'Factor' allows you to switch between the original shape and the 'cast' shape.
