Removes cached chunks for this world only. World can be regenerated from seed.
Preparing your world... This only happens once!
Web Workers offload terrain and mesh generation to background threads for better performance.
0 = Auto (75% of CPU cores, rounded down). Manual max = CPU cores − 1. Higher values may improve chunk loading but use more resources.
Worker changes take effect on next world load.
Resolution or AA changes require a reload to apply.
Shadow quality and bias changes may require a reload.
Per-pixel surface response — how shiny each material reads, and glass transparency.
Shiny terrain texels (stone mica, bedrock specks, snow & sand sparkle) mirror the live sky gradient — tracks day/night. Needs Reflections (Shininess) on. Quality feature, off by default.
Per-channel light absorption. Red absorbs fastest in real water.
Distorts view through water surface. Disabled in Fast mode.
V-shaped wake when walking through shallow water.
Effect changes may impact performance.
Scales cloud + star particle counts. Particles are cheap, so High is still light.
Cloud/star changes may impact performance. Particles are cheap — push density high if you like.
