Making the grass map

The grass map is a lot like the geovent map we discussed earlier. It's a boolean (black/white, on/off) map that says where the grass goes.

To place grass, select the 'edit grass map' button in the Spring Mapping wizard, highlighted below:

This will make L3DT display the 'Spring-Grass' map and open the 'indexed map brush' tool (as shown below), which we'll use to apply the grass.

Note that the map shown above has the texture image drape applied. If your 'Spring-Grass' map appears to be all black, press the 'Apply image drape' button in the Spring Mapping Wizard.

Placing grass

To place a patch of grass, first select the 'Grass' option in the value drop-list, as shown below:

Before painting, you are also recommended to increase the brush radius (e.g. to 5) and select the 'Spraycan' brush pattern, as shown below:

Then, to place the grass, simply left-click the brush tool on the map (or click-and-drag), as shown below:

To remove grass, select the 'None' option in the value drop-list, and click on the existing grass.

That's it for the grass map. The next step is to clear the image drape.
