Opening settings
Open settings from the Editor controls. Settings are saved in your browser local storage, so they persist for you on that browser but are not shared with teammates and are not part of the project export.
Settings change how the Editor behaves and renders. Project metadata changes, layer edits, modifiers, and assets are separate from local settings.
Appearance
Theme can follow the system preference or be forced to light or dark. Display height scale visually exaggerates terrain elevation in the viewport; it does not change exported terrain data.
Vector readability boost is enabled by default. It makes vector overlays easier to see by increasing contrast and readability over textured terrain.
Performance
Working resolution controls the terrain mesh sample count. The available values are 128, 256, 512, 1024, 2048, and 4096. Higher values allow finer terrain work but use more memory and GPU time. The value locks while unsaved sculpt edits exist.
Model draw distance controls how far placed 3D objects are rendered. Raster preview max edge limits how large raster previews are decoded for the viewport. Renderer API defaults to WebGPU and can fall back to WebGL for compatibility.
DEM interpolation controls how height values are sampled. Nearest preserves pixel steps from the source height map, while bilinear smooths between source pixels.
Lighting
Sun, sun elevation, sun intensity, ambient intensity, and exposure control viewport lighting. These are visual/editor settings, not map data.
Shadows and sky background are off by default because they cost performance. Enable them when checking screenshots or preview captures, then turn them off if the viewport becomes slow.
Project settings inside the Editor
The Editor also has project-level settings stored in project metadata. One example is road traffic side, which affects road and junction behavior. Unlike local settings, these are part of the project state and can affect future export behavior.
Project metadata is saved through the API after changes. If the Editor reports that it failed to persist terrain or placement changes, wait for the error to clear before exporting.
