How do you "separate" or "explode" a 3D mesh in Godot? (self.godot)

I'd like to create an effect similar to 2 death animations that exist in Crash Bandicoot 3.

In one of them, Crash is disintegrated: all the triangle faces get separated and fly apart. A similar triangle separation is seen when he dies from fire, the triangles fall separately.

The second is a simple separation of the legs and torso. One enemy that exists in the 1st stage can cut Crash in half, which will cause the torso to stay in place while the legs walk away.

1 sounds like it could be done with a shader, 2 would be an animation. Could probably also do 1 as an animation (here it a way to do it in Blender)

Animation Tree was my first thought. Sounds like a death animation.

What kind of shader would be used for that exploding faces effect?

I know I could get a similar effect with animation, but I want to actually separate 1 object in 2, a full blown dismemberment. One way I saw this being done is by hiding (or scaling to 0.001) the blown off part and spawning a new mesh/object that represents just that piece, but is there another way?

🤔 I’d thought a vertex shader might work but I don’t know enough about shaders to actually get something out of it.

A separate mesh is how I’d do dismemberment, doesn’t look too hard to set up!
