About this project
What does Skyblock Builder add?
Porting information for 26.1 update

This mod allows you to create custom skyblock islands via config.
You simply create a schematic file using the structure block from vanilla Minecraft, or the Structure Saver item and
set possible spawn points for the island.
This mod is required on server and client side. It adds a "Skyblock" world type at "More World Options..." setting when
creating a new world on client side.
For servers, use skyblockbuilder:custom_skyblock (1.18+: skyblockbuilder:skyblock) as world type in
server.properties or in forge-common.toml (config, was removed in 1.19).
This mod requires LibX.
