This tool helps you procedurally create basic islands in various sizes and shapes straight to Unity's Terrain-object!

This tool uses Cellular Automata to create the shapes of the islands and a custom algorithm by me to smooth and create the shores for the generated islandshapes.

You can easily modify the generated islands with Unity's Terrain shape-tools to finish the outlook of your islands by shaping, painting more textures and adding trees, bushes, grass, etc. Any way you want!
