Very nice shader!
What kind of mesh should you put it on? I put it on a subdivided plane mesh, but am wondering if that’s the intended way.
Can you provide the textures ?
I don’t know what I’m doing, but it doesn’t seemt to work in Godot 4.2.
I changed the values “hint_albedo” for “source_color” and “hint_black” for “hint_default_black”. That’s what I found in Godot’s official documentation.
It doesn’t throw any errors now, but there is no visible effect on the mesh. (I’m using a flat plane)
Ok, so for anyone who is having trouble with this:
1) First make sure to adapt the shader to Godot 4:
Change the values “hint_albedo” for “source_color” and “hint_black” for “hint_default_black”.
2) Then create a QuadMesh, set its size to 1000 x 1000.
3) Subdivide its width and depth by 100. Make sure orientation is Face Y.
4) Then go to Geometry -> Material override -> New ShaderMaterial
5) Assign this shader. Set the Height to at least 50.
6) Assign whatever textures you want for the mountains and sand.
7) Create a New Noise texture and alter it however you want.
