Profile i

Relative shares for the selected profile.

Classic: all Farmland, one uniform sheet of crops. Nothing is sent to the generator and the render is unchanged.

Land cover i Fill ground i Caves i Minecraft version i

The world targets the version you pick. A NEWER client opens it fine; an OLDER one does not. Convert it with chunker.app instead.

Extend build height i Bake lighting (LOD mods) i

For LOD mods (Voxy, Distant Horizons) and map renderers only. Minecraft itself re-lights chunks as you load them, so in normal play you will not see a difference; it is not a fix for a world that looks dark, and it does not affect buildings.

Auto-centers on the selection (region corner, 4 cells meet).

Border & zones servers i

Rings: actual border, soft (+km safe edge), hard (+km wall / trim), lime internal line. Exports regions.yml + point files + border.sk to <project>/border/.

⚙ Ring, margin & script settings

Ring & margin

soft band blocks hard wall blocks damage ♥ / s trim margin km border pts internal line pts auto internal line

Server script (border.sk)

export border.sk (packet-particle walls; enforcement + titles are native WorldGuard flags in regions.yml)

render radius wall H ± update ticks

border.sk needs only Skript + SkBee. The bounce at the soft ring (exit: deny) and the Entering/Leaving titles are WorldGuard region flags, no Skript addon involved.
