Coloration in Gaea is based on CLUTs, or color lookup tables. As 2D heightfields are essentially a grid of numbers ranging from 0.0 (lowest) to 1.0 (highest), CLUTs are represented as gradients which are mapped to those heights.
The lowest part of a gradient corresponds to the lowest part of the terrain. The highest part of a gradient corresponds to the highest part of the terrain. Everything in between is evenly distributed.
Click anywhere in the gradient to create a new stop. Drag the stop to position it. Select the stop and press
DEL to delete the stop.
You can use Input Clarity instead of interjecting an Autolevels node to the graph.
In this example, a @flow is mapped by CLUTer to create basic texture map.
For general information on creating color textures, see @Color-Production.
|Input Noise||Introduces noise to the incoming grayscale map.|
|Input Clarity||Applies localized contrast enhancements to the incoming map.|
|Input Auto Level||Applies an autolevels filter to the incoming map.|
|Reverse||Reverses the mapping of the gradient.|
|Color Noise||Introduces minor color distortions to the map.|
|Output Clarity||Applies localized contrast enhancements to the output texture.|
|Output Auto Level||Applies an autolevels filter to the output texture.|
