What is ATi Structures?

2 parts

ATi Structures is a structure mod. It adds 56 handcrafted fantasy and medieval structures to your world, and they can show up both above and below ground. So if you like stumbling on dungeons and ruins while exploring, this mod gives you more to find.[1]

The structures are built using vanilla features only, with no custom blocks or entities. That is why the mod's author says it is fine to add to any modpack.[1]

In this pack

The pack's mod list shows ATi Structures 1.4.5, with the file named ATi Structures V1.4.7.jar. It has been in the pack since version 1.0.2 or earlier.[2]

Compatibility

The mod's project page lists full compatibility with several terrain and biome mods: Terralith, Geophilic, JJ Thunder to the Max, William Wythers' Overhauled Overworld, William Wythers' Expanded Ecosphere, Biomes O' Plenty and Oh The Biomes We've Gone.[1]

How do you get started with ATi Structures?

1 part

ATi Structures adds buildings to your world, so the first thing to do is head out and find them.[1]

The mod adds 56 handcrafted fantasy and medieval structures to your world. They can appear above ground and below ground, and they are built using vanilla features only, with no custom blocks or entities.[1]

What to do first

  1. Set out exploring. The structures are part of world generation, so you find them by travelling, both on the surface and underground.[1]
  2. Look inside what you find. The mod's loot tables were rebalanced in this version, so the structures are worth checking for rewards.[1]
  3. Keep an eye on the mobs. The project page says this version includes custom items and modified mobs, so don't expect a purely vanilla fight.[1]
Tip: This version changed structure generation so you shouldn't see floating structures any more, and structure distribution was improved for better world spawn. If you do find something odd, it's worth knowing that was a stated goal of the update.[1]

Unverified The sources here show no recipes, quests or config files for ATi Structures in this pack, and they don't describe the custom items the mod mentions. That means there is no crafting order to follow and no pack-specific values to quote for this mod.
