Lost Cities Modern Tweaks (Lights Off Edition)
by morriswmz
Lost Cities Modern Tweaks (Lights Off Edition) is a datapack that removes most light sources from the Lost Cities world generation, making the cities darker and more challenging.
What it does
The datapack is built on the Modern Tweaks content of the same family and keeps most of it, except that most light sources are taken out. Street lamps are removed completely, lanterns in building parts are gone, and lights on railway systems are swapped for blocks that do not emit light. Because it touches parts of the base mod, such as the places that use torches, it is intended to suit post-apocalyptic settings and players who want a darker city.
The datapack needs The Lost Cities installed, since it only overrides specific datapack files of that mod, including the world style file for everywhere and the city style file for borders. Installing it together with the Modern Tweaks datapack at the same time is not supported. Environment wise, the server requires it, while clients can join without installing it. The mod is released under the MIT License and is not open source, and it has been published for 1.20.1, 1.21.1, 1.21.11, 26.1.2 and 26.2.
Files exist for Fabric, Forge and NeoForge, with the latest builds for 26.2. The datapack was tested with several vanilla Lost Cities profiles, but it could not be tested in heavily modded environments that alter world generation. Problems caused by it should be reported to its author rather than to the Lost Cities mod.
Key features
Most light sources removed
Torches and other light sources are taken out of the city generation, leaving most areas unlit.
Street lamps removed
Street lamps are not generated, so roads and sidewalks have no lighting fixtures.
Lights replaced on railways
Light-emitting blocks on railway systems are replaced with blocks that do not emit light.
Shared content with Modern Tweaks
The rest of the content matches the Modern Tweaks datapack, with its tweaks moved under the lcmt namespace.
