Generating smooth cube terrain using perlin noise?

Recently decided to do some light scripting and decided to go with terrain generation, cubic terrain, to be exact, meaning terrain is split into 4x4x4 cubes, I searched around for tutorials about this but they were either completely different or just overall non-existent :P

If you could provide me with a simple method on how to do this and an example if possible, that'd be greatly appreciated.

I am actually doing that now. However I have only been able to create layers of Grass Dirt, Stone, Larva, And bed. I haven't been able to develop any type of land yet. vamps108 0 — 5y

This question made me look for my old thing. I eventually found it, though I assure you this ain't really focused on, so imperfections may occur.

I have long abandoned fiddling with perlin noise so I can't provide you details and simple methods. Sorry.

I realized my script is somewhat heavy. Meh, it's just three-step process. Y_VRN 246 — 5y
