Generate procedural terrains in Unity. This is not intended to be a replacement for any of the feature rich terrain generators on the Asset Store. It's intended for easy prototyping. The terrains adequate and, with a bit of work, maybe even useful.

Setup a Digital Painting scene as per normal process.

Add the Terrain Plugin to your scene.

Ensure that the terrain plugin is configured correctly. There are a couple of sample setups (Hills_ProceduralTerrain_PrefabSO and Mountains_ProceduralTerrain_PrefabSO) to get you started.

You should have a warning at this point that the terrain does not exist in the scene. Click the "Instantiate Prefab" button and a terrain will be generated for you

This project has its roots in Sebastian Lague's Procedureal Landmass Generator available on GitHub. If you are interested in how it works then you should check out his excellent tutorial Series Playlist. Check out his other videos too, there is some really good stuff on there.

Thank you Sebastian.
