This behavior pack adds new generation under Y level 0, which is already included in Minecraft Java edition snapshots, however so far in Bedrock Edition C&C there is no interesting generation down there, so let's fix that!

This pack includes generation of following blocks and features under Y level 0:

• Deepslate
• Stone (only between levels 0 and -8)
• Glow lichen
• Dripstone block
• Pointed dripstone
• Tuff
• Brown and red mushroom
• Water and lava blocks
• All ores corresponding for Y levels under 0
• Amethyst geodes
• Dripstone caves
• Mineshafts
• Spawning of Axolots, Glow Squids, Bats and all other cave mobs
• Lush Caves

Deepslate blobs and Tuff blobs between Y level 0 and 16 are removed as they aren't supposed to be in the final release of 1.18!
Because this pack adds a lot of new generation to the game, it can very slightly impact loading time of your worlds. In the 1.5.1 update, I changed a lot of code to be a lot faster!

This pack works on all MC versions above 1.17 including betas.
Following experimental features are needed for the pack to work!

If you want to see some examples of the generation, take a look at the screenshots provided below.
