Split meshes with Mesh Tools

This is a useful tool for Unity that allows you to clone, invert, split and flip meshes, move and rotate pivot point, uniform scaling, snap to grid and transform textures.

This tutorial is on how to split a mesh into submeshes to apply multiple textures or split the mesh into separate child objects.

Looking for a tool that can be used to make "broken prefabs".
Maybe "destructible prefabs" might be a better description...

This means a tool that will both split and detach an object's triangles or faces.
These split tri's to be separate (detached) objects that then can have colliders and rigid bodies applied and can be made into a (broken) prefab.
Can this tool do this please?
