Select the Land Cover Task Mode by clicking on the icon near the top left corner of the screen (above the S@G window).

• Double-click on Ground Effects in the S@G menu to open it's editor. (Note: if you have more than one ground effect you can either expand the object tree and double click the one you want to edit or you can move through the available effects once the editor is open by clicking the < and > buttons on the right side of the editor.)
• On the top of the editor there is a resolution field. Click the get button next to it and the resolution should now read 3m.
• Click the material tab, then click the T button next to the diffuse color box to open the texture editor. The default texture in the texture editor is fractal noise.
• Click the down arrow under the Selected Element and scroll down to terrain parameter.
• Change the texture parameter to Slope. What this parameter will do is apply colors or textures to the terrain based on the slope of the underlying polygons. The color gradient controls the colors that will be applied to the terrain. With the default input settings the color to the left of the gradient will be placed at the areas where there is no slope and the color at the right of the gradient will be placed at the areas where the slope is 90 degrees.

The gradient colors that WCS uses are randomly generated, so your colors will most likely not match my colors. I'm going to use three colors for the basic ground colors. These will be changed later when I add foliage.

• Click in the center of the color gradient to add another color pin.
• Select the far left color pin and then click the color box under the selected color heading (not the T button) to bring up the color editor.
• Change the color to a green grass color.
• Select the next gradient pin (Note that the color box changes according to which pin is selected) and change the color to a dry ground color.
• Change the last pin to a light grey rock color.

Finally we need to adjust the values of where these colors will be applied on the terrain. Leave the first pin at 0%, set the second to about 20% (Note: the gradient position box to the right allows you to numerically place the pin position) and set the last one to about 40%. Render a preview again. This time you should get a mostly green terrain with some dirt color sprinkled around and maybe a few spots of your rock color. This isn't too impressive because the terrain is fairly flat, but once we start on creating the island this will help us visualize how steep or rough the terrain is.
