Terrain Experiments with Blender Geometry Nodes

In this file there will be a GN modifier that has different setups scattered around inside.

You should be able to pick up how it works and techniques on how to get good terrains.

This is more of a 'learning how to do it' than a reusable asset, though you can use it for that.

It is a simple setup, and here to show you what one Musgrave or mixing it with other textures can do.

If you want it to work on all meshes, and not only a grid you should use the offset by normal scale, shown in some of the examples.
