Regenerate keeps the current seed. Random Regenerate creates a new seed and immediately rebuilds the world.
Custom biome terrain uses the procedural terrain generator, with an optional Poly Haven PBR ground material. Built-in biomes never use this texture.

🌿 Render-Area Object Population
Set a 0–50 object budget per loaded chunk for Trees, Rocks, Plants and Props. AUTO preserves the original biome/density-driven rendering exactly.
Normalizes each GLB by its real bounding-box height, then fits it to its category so trees, rocks, plants and props keep believable proportions. Ground contact is corrected automatically.
0% = normal procedural objects only · 100% = GLB whenever the category has a loaded asset · loaded GLBs trigger an automatic world rebuild
Automatically searches suitable GLBs for the active biome and places them with terrain-aware scale, rotation and spacing.
Low mode keeps online assets at the smallest selected delivery, disables their shadows, and uses a 1× renderer pixel ratio for large worlds.
Low is recommended for large worlds. Each asset falls back to the nearest available Poly Haven resolution.

GLB is a finite, importable snapshot for Unity / Unreal. JS exports the selected world configuration, online asset URLs, HDRI settings and deterministic chunk streaming for an infinite browser runtime.
