How to add vertices to a cube

I want to add vertices to a cube procedurally, so make it more high poly.
How is that possible? I cant find anything in the procedural examples.
Maybe also something like tessellation is possible in unity?

Thanks in advance.

Try [that][1].

Tesselation is probably simple, once you know how to isolate a face, spliting in four and moving on. Smoothing, that’s another business I guess.
