Terrain Automation Tools

Terrain Automation — 10 World Editor tools for fast, natural terrain decoration. GENERATION TOOLS Auto-Decorator — Scatter prefabs with Poisson disk distribution. Weighted palette system with per-prefab scale, spacing, slope filtering, and collision avoidance. Save/load presets. Works on selection box or entire terrain. Terrain Randomizer — One-click terrain population. Analyzes slope, altitude, and water proximity to assign contextual prefabs across terrain zones automatically. Biome Painter — Click and drag to paint biomes. 6 built-in templates (Temperate Forest, Pine Forest, Tropical, Arid, Grassland, Mixed) with multi-layer vegetation (canopy, understory, ground cover, rocks). Ctrl+Scroll to resize brush. Path Decorator — Click to place waypoints, generate Catmull-Rom spline paths. Scatter prefabs along corridors with rotation modes (Along Path, Perpendicular, Random) and multi-row support. Elevation Band Tool — Define altitude bands (Shore, Lowland, Midland, Highland, Alpine) with unique prefab sets per band. Load defaults or customize ranges, spacing, and density. EDITING TOOLS Entity Eraser — Brush-based deletion. Filter by name, current layer, or erase all. Drag to continuously erase. Ctrl+Scroll for radius. Density Painter — Thin or thicken existing decoration. Thin mode removes a percentage; Thicken mode spawns more of the same prefab types found nearby. Hold SPACE to toggle modes. Object Replacer — Batch-replace selected entities with a different prefab. Optional source filter, keep/randomize transforms, preview match count before replacing. Forest Featherer — Select a group of trees, auto-detect edges via neighbor density, then thin and shrink edge objects for natural forest boundaries. Corridor Clearance — Click waypoints to define a spline path, then clear all entities within the corridor. Configurable width and buffer zone with gradual thinning. Perfect for roads and rivers. All tools support full undo (Ctrl+Z), skip terrain entities, and run directly...
