1986 High Gilbert Stansbury Provo Bonneville

Regional terrain is loaded from a performance-optimized USGS 3DEP bare-earth elevation grid. The 129 × 129 preview is intentionally lighter for smooth browser use; exports preserve the same geographic footprint. Regional Relief defaults to 25%, the natural-looking overview baseline. The maximum Lake Bonneville outline uses Utah’s official historic-lake polygon.

GPU-instanced preview objects follow biome, moisture, elevation, slope, and shoreline rules. Analysis layers hide scenery automatically. Regional objects are visually enlarged for an overview, while exported positions and scales remain in real-world meters.

Maximum Heightmeters

Unity terrain will be centered at world origin. Current water height above terrain base: 36.0 m.

These dimensions control physical scale, exported slope analysis, and the Unity Terrain size. They do not change the editor camera.

The still render uses the current camera view. High and Ultra temporarily increase scenery density, lighting quality, sky styling, and weather for a single PNG export.

Export & Import

Biome, slope, and moisture maps use the same sculpted terrain shown in the viewport. Project JSON preserves height data, surface rules, environment settings and placements, and game-engine scale settings.

Controls

Drag to orbit. Scroll or pinch to zoom. Right-drag to pan. The same seed and settings will always regenerate the same terrain.
