Brushes

A brush is a black and white picture. It sets how strong a tool is at each point under the brush: white is full strength, black is no effect, and grey is in between. Every sculpt and paint tool in the Terrain Tools uses the brush you pick.

Pick a brush​

  1. Open the Terrain Tools and turn on Sculpt or Paint.
  2. In the Brushes grid, click a brush.
The Brushes grid in the Terrain Tools panel

RustEdit comes with 18 brushes: soft round brushes, a square brush, and textured brushes with speckles and noise. A soft brush fades out to its edge, so its strokes blend into the ground around them. A textured brush gives a rough, natural look.

The brush you pick is used by every tool. The Stroke settings set its size and rotation. See Stroke settings.

The Stamper does not use these brushes: it has its own height pictures. See Clone and Stamper.

Add your own brushes​

  1. Make a square PNG picture in black and white. White is where the tool works at full strength.
  2. Put the file in your Brushes folder. By default, this is the Brushes folder next to the RustEdit app. To use another folder, set it at FileSettings, in Paths > Brushes.
  3. Restart RustEdit. Your brushes show in the grid after the built-in ones.

If the Brushes folder is not there, RustEdit makes it.

tip

Keep the edges of the picture black. The tool has no effect outside the picture, so white edges give a stroke with hard, square edges.

note

RustEdit reads the red channel of the picture. Use a grayscale picture: in a colored picture, only the red part counts.

The greys of your own brushes work weaker than the same greys in the built-in brushes. A 50% grey works at about 20% strength. White and black work as expected. If the soft edge of your brush fades out too fast, make its greys lighter.

The filter-stacks folder​

The Brushes folder also has a filter-stacks folder. RustEdit saves the filters of each tool there, one file per tool. A tool with no filters has no file. To start a tool with no filters, close RustEdit and delete the tool's file. RustEdit saves the filters again when it closes, so a file deleted while it runs can come back.
