| Texture | The filename of the image to be used as the water surface texture. If no filename is specified, a default texture is used. Note that the texture (if used) must be placed in the 'maps' directory within the SD7 archive. |
| Surface colour | Possibly (?) the colour of the specular highlights from the water reflection. |
| Plane colour | The colour of the 'water plane' outside the map's bounds. Press the button to change the colour. |
| Base colour | The colour of the water at the surface. |
| Minimum colour | The darkest colour the water will become due to absorbance (see below). |
| Absorbance (red/green/blue) | The absorption strength of the RGB light colours in water. |
| Damage | The amount of damage done to units in water. This value may be used to make acid lakes, for example. |
