Adding Color to Terrains


Color in the Terrain Editor is used as a visual aid to help you see the relationship between color values and altitude. This color only exists in the Terrain Editor and is not applied to the terrain object.

When you apply color in the editor, it maps a gradient to the altitudes in your Terrain Canvas. For example, if you apply a gradient from blue to yellow, blue might represent the lowest altitude while yellow may represent the highest. Which colors are mapped to which altitudes is left completely up to you.

Gradients can be extremely useful when you're filtering terrains, as they emphasize the differences between gray levels.

Mapping Color to Your Terrain Canvas

The Terrain Editor's color picker contains all the gradients you can apply to your terrain. The gradient you select is applied to both the Terrain Canvas and the 3D Preview.

To map colors to your Terrain Canvas:

1 Click the Color Picker button in the bottom right corner of the Terrain Canvas Frame and drag over a gradient in the palette.

The gradient you select appears in the Gradient bar and is mapped to the Terrain Canvas and the 3D Preview.

2 Drag the gradient up or down to map the colors to altitudes.

The colors at the bottom of the gradient represent the lowest altitude and those at the top represent the highest.

The Gradient Bar has two modifiers:

To return to grayscale:

Although gradients are meant to be used only in the Terrain Editor, you can apply the gradient to the terrain's Diffuse channel. The gradient then becomes the terrain's Diffuse color. This allows you to render the gradient with the terrain.

To remove a gradient from a terrain's Diffuse channel:

1 Open the terrain in the Terrain Editor.

2 Click the Color/Grayscale toggle.
