About this Mod

X-Ray World Datapack

Have you ever used an X-Ray Resource Pack? Have you wondered "Man, I wonder what it would be like if the entire world was actually like this."

...What do you mean no?

Well, I made a Datapack that does that anyways. The world looks completely normal except for the fact that most of it is missing... Only ores and the shell of structures are left in the world... You'll most likely spawn on a coal ore vein at y=0 in the middle of no where, stuck floating above the void. But hey! At least Diamonds are easy to find, right?

This is not an x-ray mod / How to use:

  1. This is NOT an X-Ray Mod / Resource Pack. This is a World Generation datapack. It overrides the default world generation to remove terrain.
  2. To use, install the datapack / mod and create a new world.
    • If you are having issues with this, it may be because some issue with porting the datapack as a mod. File a bug report either on my discord or the github page. Include info like mods used, mod loader used, error, version used, etc.
  3. Custom world options are not supported (superflat, amplified, etc. I may add support in the future).
  4. This is incompatible with biome mods, and might be incompatible with some terrain mods.

Shout out to Apollo for discovering the technique to make this datapack possible!
