Lost Cities Modern Tweaks

This datapack (packaged as a mod for easier installation) applies many tweaks to the default Lost Cities geneartion on 1.20.1, making generated cities more interesting while trying to keep the original style.

⚠ You need to have The Lost Cities installed to use this datapack ⚠

Example tweaks:

1. Replaced all torches with lanterns. Unfortunately lanterns still generate when city lighting is disabled because torches are hard-coded light sources. You can use Lost Cities Modern Tweaks (Lights Off Edition) if you don't want those lanterns to generate.
2. New street and highway designs. Streets now have lamp posts.
3. Added more details to the railway network.
4. Added more details to some existing buildings.
5. More roof variations.
6. More park designs. Some existing park designs are also tweaked.
7. Redesigned fountains to better fit the new streets.
8. More building palettes.
9. A new factory multibuilding with a spacious interior, which can be a convenient place to kick off your factory in tech packs.
10. New building designs.
11. New biome specific city styles.
12. And more ...

In general, most of the tweaks are aesthetic, and won't break the balance from the original mod. There are 200+ modified building parts. You can visit the gallery for some examples.

I started these tweaks in my own playthroughs, when I found it strange that a modern city still uses torches everywhere. As I added more and more tweaks, I figured that it is also a good idea to share these tweaks with you.

Permissions

Feel free to use this datapack in any modpacks. The MIT license also gives you a lot of freedom to do additional tweaks yourselves (as the source files are just json files included in the pack).

Compatibility

This datapack has been tested with various vanilla Lost Cities profiles. However, it is impossible to test every heavily modded environment that heavily modifies worldgen. So if the datapack works flawlessly, that's great and enjoy it! If not, you may have to remove it, or manually resolve the issue if you are experienced. Do not report issues caused by this datapack to the Lost Cities mod!

Compatibility with Other Lost Cities Datapacks

Highly unlikely for the following reasons:

• This datapack modifies lots of parts from the base mod (e.g., it touches all parts with torches).
• Currently the Lost Cities mod does not support merging city styles or building definitions (e.g., allowing multitple datapacks to add/alter different buildings to the same city style). Therefore one pack's content will usually override another's.

Compatibility with Other Mods

It should be compatible with mods that are compatible with The Lost Cities mod. The lootable chested/barrels added by this datapack are also compatible with mods like https://modrinth.com/mod/lootr.

Dependencies

• The Lost Cities

If you are using the mod version, dependency check should be automatically performed by the mod loader. However, if you are using the datapack version, you must manually verify it is compatible with version of the Lost Cities mod you installed:

• Minecraft 1.20.1: You need The Lost Cities 1.20-7.3.6 or above starting from Lost Cities Modern Tweaks 1.0.7.
• Minecraft 1.21.1: You need The Lost Cities 1.21-8.2.6 or above starting from Lost Cities Modern Tweaks 2.0.4.

FAQS

I see both the mod version and the datapack version. Are there any differences?

They share the same content. In general the mod version should be easier to use as you can simply install it as a mod, which will enable the tweaks for all worlds. If you only want to enable these tweaks for a specific world, you can download the datapack version and add it to that world only.

I don't see any city generated?

Follow the instructions from The Lost Cities mod and make sure city generation is turned on for your world. This datapack should work with all default lost cities profiles.

I turned off generateLighting, but lanterns and other light sources still generate in cities?

Unfortunately, that option currently only works for torches. I created a separate pack with most light sources removed here.

If you are familiar with configuring datapacks for lost cities, you can also make a datapack changing the light source definitions in the following palette files:

• lcmt/lostcities/palettes/lanterns.json
• lcmt/lostcities/palettes/soul_lanterns.json
• lostcities/lostcities/palettes/rails.json

Is it possible to support older versions than 1.20.1?

This datapack uses blocks from Minecraft 1.20.1+ and some features only available in 1.20.1+ versions of the Lost Cities mod. So older Minecraft versions are not supported.

Can I tweak the loot in multi-building like the factory buildings?

Yes. All loot tables are defined under lcmt/loot_tables/chests (or lcmt/loot_table/chests for 1.21.1 and above) in the datapack. The selection conditions are defined under lcmt/lostcities/conditions.

For example, with the default condition defined at lcmt/lostcities/conditions/factory_loot.json, lootable chests or barrels in factory buildings will pick one of the loot tables from lcmt/loot_tables/chests/factory_*.json (or lcmt/loot_table/chest/factory_*.json for 1.21.1 and above) to generate loot items. The loot tables are balanced against vanilla. If you are a pack maker, you can use mods like KubeJS to edit them to make them better fit your pack.

Some multi-building's loot conditions are configured to allow different loot tables to be used in different building parts. For example, if you want to customize the loot in shopping center's vending machines, you can override lcmt/loot_table/chests/shopping_vending_machine.json.

Can I tweak the biomes for specific city styles (e.g., snowy cities)?

Yes. By default this datapack uses biome tags to determine desert, jungle, and snowy biomes. So it should be compatible with biome mods that correctly set biome tags for their new biomes. You can also manually override the corresponding biome tags under lcmt\tags\worldgen\biome in this datapack if you need more fine grained tweaks.

I saw errors like Failed to create block entity minecraft:banner in logs. Should I be worried?

You should be fine. The Lost Cities mod seems to have a bug when generating banners under certain situations. As a result, the banners won't be generated correctly in some building parts, but it should not affect gameplay.
