Brush editing
The brush lets you hand-edit and sculpt terrain after generating it, giving you fine control over specific features. Tweak the coastline, carve out valleys or river channels, flatten building spots, and refine elevation before exporting. Toggle it with the Brush button in the toolbar or press B. A small panel appears with brush controls, and live preview updates as you paint so you see terrain changes in real time.
What brush types are there?
Section titled “What brush types are there?”- Flatten: levels terrain toward a set height. Use it to carve a flat building spot, create a plateau, or prepare a specific area for monuments. Ctrl + right-click on terrain to sample the height you want to flatten toward.
- Raise: pushes terrain up. Good for adding a hill, reinforcing a ridge, or lifting a low area to add more buildable ground.
- Lower: pushes terrain down. Use it to deepen a valley, cut a river channel, or create a sunken area for water features.
- Smooth: softens and blends terrain, evening out rough spots. Apply it after other brushes to blend transitions, or use it to calm noisy terrain if the generation is too chaotic.
What do the brush controls do?
Section titled “What do the brush controls do?”- Size (5 to 80, default 30): the brush radius in pixels. Small (5-15) for detail work like carving small channels, medium (20-40) for general terrain tweaks, large (50-80) for broad sweeping changes.
- Strength (0 to 100, default 50): how strongly each stroke affects the terrain. Low (10-30) for subtle blending, medium (40-60) for normal adjustments, high (70-100) for aggressive terrain changes. Start low and build up in layers for better control.
- Hardness (0 to 1, default 0.6): how sharp the brush edge is. Lower (0-0.3) gives a soft, feathered edge good for smooth blending, higher (0.7-1) gives a harder edge for precise cuts and defined features.
- Height (0 to 1000 m, default 550): used only by Flatten, the target height it levels terrain toward. With Flatten selected, Ctrl + right-click on the terrain to sample a height into this value, then paint to flatten at that exact elevation.
- Hold Space while brushing to move the camera, then release to keep painting.
- Brush strokes are undoable with Ctrl + Z.
- Randomize (Conjure) is disabled while brush mode is on. The brush currently breaks slider interaction, so terrain generation is locked until the brush is deactivated. This limitation will be fixed in future updates.
