You want to visualize a water body in a realistic way. For example, you want to model a pond or a river within your terrain and you want it to have a texture of moving water. You can create an effect as in the illustration below:
Create the water body
Draw a polygon around the area you want to see as water
Right-click the polygon and click Properties
Set the Fill Opacity to 100%
Type $$WATER$$ in the Texture File field
You can change the Scale X and Y to make the waves larger or smaller.
After conducting these steps you will see a water body with a realistic water texture.
Level the water body
The next step is to make sure that the water surface is flat as in reality:
- Change Altitude Method to Absolute in the Properties window
Set the Point Altitude to the same elevation for every vertex in the Points position section. You can navigate from point to point by changing the selected point.
- Set the Altitude parameter in the Properties window (Position section)
