About this Mod
Description
Removes blocks such as andesite, granite, dirt, and gravel from cave generation. Also removes similar blobs in the Nether. Does not remove surface blocks, such as dirt, and many of these can be crafted or found in other places. Leaves ores in the same places.
Similar packs, such as this one (which does not remove dirt blobs), have been made in the past. I have come across that pack, and decided it would be different enough to not be a direct copy. Please support other creators who had the idea first.
Versions
Supports Java 1.21.5 - 1.21.11
Compatibility
May be incompatible with some cave- or Nether- related worldgen packs. When used along with my Natural Gilded Blackstone pack, this pack will always take priority and the modified veins will not generate.
