Level Editor/Panels/Terrain
The Terrain tab (bottom right) holds the brush settings for the Paint / Sculpt Terrain tool: what the brush does, how big and strong it is, and the terrain's texture layers. How to create a terrain and use the tool is on Terrain.
With no terrain selected the tab says Select a Terrain to sculpt or paint.
Mode
The Mode list chooses what a stroke does:
- Sculpt: change the height of the ground, or cut holes in it.
- Paint: paint texture layers.
- Detail (resolution): change how finely tiles are divided.
- Scale: change how large the textures tile, per spot.
Brush
These apply in every mode.
| Setting | Type | Default | What it does |
|---|---|---|---|
| Brush size | Meters, 0.05 to 64 | 4.0 | The brush's radius. [ / ] change it. |
| Brush strength | 0.05 to 32 | 4.0 | How strongly each stroke works. Shift+[ / ] change it. |
| Brush shape | List | Circle | Circle, Square or Diamond. |
| Brush rotation | Degrees, 0 to 360 | 0 | Turns a Square or Diamond brush. |
| Falloff | List | Smooth | How the brush fades towards its edge: Smooth, Linear or Hard (no fade). |
| Spacing | 0 to 2 | 0 | 0 is a continuous stroke. Above 0, the brush stamps separate dabs this many brush radii apart, for scatter strokes. |
| Jitter | 0 to 1 | 0 | A random offset for each dab, in brush radii. Use it with Spacing for scatter, or alone for a spray. |
| Symmetry X / Z | Toggles | Off | Repeat every dab mirrored across the middle of the terrain, along X, Z or both. |
| Show vertex grid | Check box | Off | Draws the terrain's vertex grid over it, so you can see its resolution and detail changes. |
Sculpt mode
Sculpt mode buttons choose the brush:
| Button | Key | What it does |
|---|---|---|
| Raise | 1 | Lifts the ground under the brush. |
| Lower | 2 | Lowers it. |
| Smooth | 3 | Evens out bumps. |
| Flatten | 4 | Pulls the ground towards the height under the middle of the brush. Press 4 again for angled flatten: the ground is pulled towards the slope of the surface where the stroke started, so you can make an even ramp. |
| Cut hole | 9 | Removes the ground under the brush (for cave mouths and tunnels). |
| Fill hole | 0 | Puts removed ground back. |
Stitch mirror seam: for a terrain that a Mirror Node copies onto the other half of the map. It joins the terrain to its copy where the two meet: moves it onto the seam if it is off by up to 1 m, sets each pair of meeting vertices to one height, and fades the change 4 m into the ground and 2 m into the paint so the join leaves no ridge. One undo step; later strokes keep the seam joined. A message under it reports how many vertices it joined and the largest step.
Paint mode
A terrain has up to five texture layers: the base (layer 0, the unpainted ground) and four you paint over it.
- Layer (click to paint, double-click to change material): the list of the terrain's layers. Click one to paint with it; double-click it to pick another material for it.
- Add Layer...: adds a layer from a material you pick.
- Footstep sound: what footsteps (and bullet marks) on the selected layer are like. Auto works it out from the texture's name.
- Texture scale (0.1 to 16, default 1.0): how finely the selected layer tiles everywhere it appears (below 1 coarser, above 1 finer).
- Fill tile under cursor: fills the whole tile under the brush with the selected layer.
- 5 to 8 choose layers 0 to 3 for painting.
Auto-texture by slope paints the whole terrain by its slope:
- Flat layer and Steep layer: which layer goes on flat and on steep ground.
- Flat below (deg) (default 25) and Steep above (deg) (default 50): the slopes where each starts; between them the two blend.
- Apply slope texturing paints it.
Detail mode
Region detail: drag to set hovered tiles' resolution. A terrain is made of square tiles (32 m by default), each with its own resolution. Choose a resolution and drag over tiles to set it:
- Low (9), Medium (33), High (65), Ultra (129) vertices along each side of a tile.
- Apply to whole terrain sets every tile.
Use high detail only where players walk close to it; distant ground can be low.
Scale mode
Texture scale: drag to retile (1.0 = default, <1 coarser, >1 finer). Paints a texture scale onto the ground, so one patch can tile larger or smaller than the rest.
- Scale (0.25 to 4, default 1.0): the scale a stroke paints.
- Fill tile under cursor: sets the whole tile under the brush to this scale.
