How to slash gameobject?

i have Instantiate one object that can increase to right scale only.and then i want cut it to 1,2,3…How to do it? if other guy have a script file or example like this please help me.:frowning:

Only example i saw so far is that you actually make cut models and then swap them in script when needed (tutorial here). I might be wrong here, but i doubt you can just slash models in game engine in any usable way. That would also mean you would get empty faces.
