      [1.19.2] Generate dimensions with code.

      By Master_J · Posted

      I used multiple biomes by setting the type to minecraft:multi_noise. The dimension is working fine now, but I was wondering if there is a way to supress this warning when creating a new world: Warning! These settings are using experimental features. These settings are experimental and could one day stop working. Do you wish to proceed?
