# CustomWorldHeight **CustomWorldHeight** is a plugin for Paper that allows you to modify the height of the Minecraft world. It provides an easy and efficient way to extend or limit the vertical dimensions of your world for creative builds, gameplay tweaks, or server optimization. Github page: (https://github.com/Lumine1909/CustomWorldHeight) # Important > This plugin is similar to the vanilla datapack, so there will be some similar issues as the datapack one. > > Once you set the height of a certain world, it will be VERY DANGEROUS to shirk the world height, all the data will lose. > > Expand the height is relatively unharmful, but if you decrease the min-Y, new chunks will be different from already generated chunks. > > Increasing the height will only cause the chunk's height map to be recalculated, and all the data will be properly preserved. ## Features - Customize the height of your Minecraft world. - Seamless integration with Paper. - Easy-to-configure settings for server administrators. ## Installation Follow these steps to install the plugin: 1.
