Using the all powerful menu

Heightmap Mode

Press H to enter heightmap mode. You can have an area selected then scroll the mousewheel to make hills and mountains if you want to make sure it doesn't mess up other parts of your map. You don't need an area to use heightmap, just hit H and scroll the mousewheel.


Use your third mouse button or press the mouse wheel and drag it across the top of the block you want to make the ramp from. You should see white boxes being formed as you drag. Then scroll the mouse wheel forward until you have your desired angle.

1st Method

Create a hole or area to put the water into. Use the right mouse button to select the area to fill with water. You can use F3 to then add in the water or use ` (above tab) to get into the console and type editmat water. Typing just water works as well.

2nd Method

Select where you want the water and click F3 to use the material menu or then hit ` (above tab) to enter the console. Type editmat water then ENTER. Then scroll forward on the mousewheel. To make deeper patches of water use G + mousewheel to increase the grid size and then use the editmat command.
