    How to install Minecraft Data Packs

    First tech demo in a year! It's been awhile, hasn't it?

    Since 1.18, worldgen datapacks haven't been able to extend the depth of the world due to lava always generating below y -55. There were some workarounds, but none fully worked. This changes today.

    The Depths [​Tech Demo] extends the depth of the world, moving the bedrock layer to y -128. There is no lava level, all the way to bedrock there is air. On top of this, to showcase the new tech, alternate stone generation has been massively overhauled: instead of small blobs over the place, there are massive caverns of alternate stones. These aren't tied to any biome, just go caving anywhere and you may find one.

    For anyone interested in the tech behind it, look at the contents of the datapack and this gist.

    Warning: This is incompatible with other worldgen packs, including my other tech demos.

    looks like 1.20.3 broke it. some undocumented change now causes the air geode features to replace *everything*, except for mineshafts and, ironically, other geodes. also the spawn area is completely flat in a pretty wide range with the datapack on, with seed -3905693806583539390

    edit: i removed the andesite/granite/diorite stuff from the biome files and that fixed the weird spawn, but the entire area from -48 to -128 is still blank

    edit 2: apparently mojang changed minecraft:grass to minecraft:short_grass, which made #depths:everything_but_lava fail to load, which made the geodes just replace everything?? thanks mojang. anyway yeah the method still works in 1.20.3+ just requires minor fixes

    The entire point of this datapack is to show new datapack-specific tech. Mods have always been able to get around the -55 lava limit.

    Is this compatible with Datapacks that only add structures?

    This seems like such a cool idea, are there any plans to include it in Terralith/make it compatible with it?

    Including it in Terralith: Absolutely not, as extending the world depth on an existing world leads to a bunch of issues.
    Compatibility with Terralith: Technically possible, but it requires splicing together a bunch of files and if Terralith makes a change to one of those files, something will break. Likely won't happen.
