I recently made these fully procedural materials. the first one is the Lava material, which you can fully customize as you like, e.g.(Lava color, lava glow, rock density, etc.) through an organized node group, and the second one is the Rock and Dirt material, which you can also fully customize as you like, e.g.(Rock/Dirt density, rock/ sand color, crack, etc.) as shown in the provided image.
