Set Up a Creative World Alongside Your Survival World
Create the Creative World
Use /world create creative creative to generate a new world with creative mode enabled. This creates a separate space where players can build without resource constraints while your survival world remains unchanged.
Configure World Settings
Once created, use /world flag creative gamemode creative to ensure the world defaults to creative mode. You can also set difficulty with /world flag creative difficulty peaceful if desired. Use /world info creative to verify all settings are correct.
Enable Player Access
Grant players the multiworld.teleport permission so they can switch between worlds. Players can then use /world teleport <player> creative to move to the creative world, or use /world back to return to their previous location.
Optional: Restrict Access
If you want only certain players in the creative world, use /world whitelist creative enable followed by /world whitelist creative add <playername> for each approved player. This keeps the creative space controlled while maintaining your survival experience.
