Here I have collected my modifications with which you can simulate natural waters. Among other things, you will find water textures here, with which bodies of water can be created at different altitudes and different colors. Additional foam textures are designed to make stronger currents and waterfalls more attractive.
So that the game does not build up your waters, "Collision Tiles" are available, which can protect waters and other structures from development with streets and houses.
Unfortunately, I cannot offer you things like transparent textures or navigable waters. This is simply not possible with terrain materials according to my status.
