I would like to add terrain or draw on the terrain in Godot, but for mobile. I searched in all the add-ons, there is no one that supports Android mobile.

Create a separate TileMap scene, then in the inspector create a TileSet and open it and click the TileSet button at the bottom next to the shader editor. Click the plus and add a tileset texture, then go to the TileMap tab next to the tileset, select a tile and draw.
