Cubic terrain lags

I am making a game that will make use of minecraft-like terrain, made of cubes, with ability to interact with each individual cube (destroy / create, fertilize, irrigate etc.).

At the moment i am using basic cube GameObjects as building blocks, which - while reasonable for prototyping on small 10x10x10 patches of terrain - get far too slow on anything larger.

Was wondering about any tricks to make cube-based terrain run faster.

Found this guide, which seems to outline all the techniques i’ll need in the foreseeable future for optimization :slight_smile:
