Lithostitched Mod FAQ

Lithostitched is a library mod that lets other mods and datapacks change world generation through data files instead of code. It handles biome feature injection, extra structure pieces, and terrain shape/material overrides so multiple packs can stack without conflicting.

You don't interact with it in-game — it works passively once installed alongside mods or datapacks that depend on it. To use it yourself, open your world's datapacks folder and add JSON files under the lithostitched namespace.

No. It's a dependency, so it only does something when another mod or datapack calls on it. Installing it alone changes nothing about your world.

It lets data files add, remove, or adjust features inside existing biomes without overwriting the whole biome JSON. That means two datapacks can both modify the same biome and their changes stack instead of one replacing the other.

You write a data file that targets the structure's piece pool and appends your new piece entries to it. Lithostitched merges your additions into the existing pool rather than replacing it, so vanilla and modded pieces stay intact.

Yes — it exposes terrain modifiers that adjust surface height, layer stacking, and the blocks used in those layers. You define these in JSON and they apply during chunk generation for the biomes you target.

The most common causes are a wrong namespace or folder path, a JSON syntax error, or the pack not being enabled for that world. Check the log for parse errors and confirm your file sits under data/ /lithostitched/ (or the path the mod expects).

That's its main purpose — it's designed so multiple mods and datapacks can modify the same biomes and structures without clobbering each other. As long as the other mod uses data-driven worldgen, changes should merge cleanly.

The mod itself adds little overhead because it only runs during world generation, not every tick. Heavy terrain or feature changes from the packs using it are what affect generation speed, not Lithostitched itself.

Yes for worldgen changes — biomes, terrain, and structures are baked into chunks when they generate. Existing chunks keep their old layout, so you'll only see new results in unexplored areas or a fresh world.

It is a library mod that provides tools for changing how Minecraft worlds are generated. It doesn't add its own items or mobs, but helps other mods and datapacks customize world features.

No, it is a library mod and does not add new items or mobs on its own. Its purpose is to support other mods and datapacks in customizing world generation.

It lets you add, remove, or adjust biome features using data files. These changes are handled through data rather than code.

Yes, it can add new parts to existing structures such as villages or temples. This is done through data files.

Yes, it can change the ground's height, layers, and the materials it's made of. These adjustments are made through data files.

World generation is customized through data files in JSON format, without needing to edit any code. This data-driven approach makes it easy for other mods and datapacks to make adjustments.
