Opening settings

Click the gear icon in the top bar of the Editor to open the settings panel. Settings are divided into appearance, performance, and rendering categories. All values are saved to your browser's local storage — they persist across sessions for you personally and are not shared with teammates.

Appearance

Theme: switch between Auto (follows system preference), Light, and Dark.

Display height: a visual multiplier applied to terrain height in the viewport. Increasing this value exaggerates vertical features to make subtle elevation changes more visible. This setting does not affect exported terrain data — it is purely cosmetic.

Vector readability: Boosted renders vector overlays with thicker strokes and higher contrast, making them easier to read over complex terrain. Standard renders them at their natural scale.

Performance

Working resolution: controls the density of the terrain mesh. Higher values produce a finer mesh that captures more sculpting detail but require more memory and GPU time. Once you have unsaved terrain edits, the working resolution is locked until you save or discard changes.

Model draw distance: how far away (in metres) placed 3D objects are rendered. Reducing this can improve performance on large maps with many objects.

Graphics API: WebGPU uses the browser's modern graphics pipeline and gives the best performance on supported hardware. WebGL is the compatibility fallback — use it if the viewport does not render correctly on your machine.

DEM interpolation: controls how terrain height values are sampled between source pixels. Smooth (bilinear) blends neighbouring values together for a softer look. Pixelated (nearest-neighbour) uses the raw source value for each point, preserving sharp steps in the original data.

Lighting

Ambient brightness: the global fill-light intensity. Increase this if the terrain shadows are too dark.

Exposure: the tone-mapping multiplier applied to the final rendered image. Higher values brighten the overall scene.

Screenshot visuals: enable Shadows and Sky background to get a more realistic render when taking screenshots. Both are disabled by default because they have a performance cost.
