Gaea Documentation
The documentation is being updated for version 1.3. Some sections may be incomplete.

The Constant node is the most basic primitive available in Gaea. It can create three outputs: a flat terrain of a specified height, a flat color output, or a noise pattern.

Constant is rarely used directly, but rather as a mask or a second input blended using Combine with another node.

Modes

Height

The uniform height "block" terrain can be used with Combine in Max mode to create a flat area at the specified height in a terrain.

Color

The uniform color output can be used for blending various textures or combining a flat color on top of an existing color map to modify the tint via various blend modes.

Noise

The noise output can be merged with other nodes' output to add jittery effects. In most situations, you may want to use the Noise node instead. The Noise mode was added to the Constant node to reduce the need to create a flat Constant and then apply the Noise node on top of it to create a flat noise map that could be used elsewhere in the graph.
