Floating islands you don't have to sculpt
Drag the sliders, watch the island change in the Inspector, hit save. You get a real Unity mesh with a collider. It's flat enough on top to build on, and as jagged underneath as you like.
The part nobody wants to model
The top of a floating island is easy. It's flat ground. The underside is the problem... all that broken rock hanging down into the sky, different on every island, and most of it barely visible once the camera is where it will actually sit in your game.
I got seriously bored of sculpting them one at a time, so I wrote something that does it for me.
The same generator, seven times
These are the presets that ship with it. Change the seed and you get another island with the same character. Change the sliders and you get something that isn't in this grid at all. :)
What you get
-
It updates while you drag
The custom Inspector regenerates the mesh as you move a slider, so you are choosing an island visually rather than guessing at numbers and pressing play.
-
Save writes a prefab
Mesh and textures land in your project as ordinary assets with a collider attached. Drop it in a scene and work with it.
-
Or skip the editor entirely
The API takes a position and a seed, so you can build a whole sky at runtime. Full C# source is in the package if you want to change how any of it works.
Few reviews I liked
At first I was scared because sooo many sliders and numbers... but when I play with it, it become like drawing with math!!
I started playing with the sliders and before I knew it, half an hour had gone by. As I was placing different types of floating islands, ideas just kept popping into my head...
It builds the damn rock so you can get on with your game.
