Filtering

The Filtering tab is divided into three areas: the Filtering Graph, the Preview area, and the Filtering Presets.

The Filtering graph displays your Terrain Canvas' gray levels as value inputs and outputs. You can edit this graph to adjust the gray level values in your canvas.

Next to the graph is the Preview area. This area shows you what your Terrain Canvas would look like if applied to the current Filtering graph. This area automatically updates as you make changes to the graph.

Along the top of the tab are the nine Filtering presets you can apply to the graph. Each preset represents a different predefined graph. They are designed to create specific changes in gray levels, like smooth gradients and abrupt transitions.
