Lost Cities Modern Tweaks
by morriswmz
Lost Cities Modern Tweaks changes the default Lost Cities generation by swapping in modern blocks, lamp-lit streets and new building designs, while keeping the original look of the cities.
What it does
The datapack applies a set of tweaks to the default Lost Cities generation. Streets and highways get new designs with lamp posts, railways gain more detail, and some existing buildings are expanded. Roofs, park layouts, fountains and building palettes are varied as well, so generated cities look less uniform while staying close to the original style. A factory building with a roomy interior is included as a base for factory setups in tech packs.
The Lost Cities must be installed for the datapack to work. It is packaged as a mod for easier installation, and Fabric, Forge and NeoForge files are published alongside a data pack version. The server needs it, while players may add it and gain the lootable chests and barrels in their own games. The license is the MIT License, and the project is not open source. Later releases keep most tweaks under their own pack namespace, which improves compatibility with other Lost Cities content. Its lootable chests and barrels also work with Lootr.
