Beyond the Underground (Ice Caves & More!)

This add-on adds more cave types for you to explore. Be careful of deadly mobs along the way, and you'll be able to find valuable ores for you to level-up your gear!

This add-on currently adds 4 new cave types. More will be added in future updates!

Luminous Caverns (Mushroom Caves)

  • These caves generate exclusively under Mushroom Islands
  • This is a peaceful cave with no natural hostile mobs spawning
  • The entire cave is slightly lit up with vegetation!

Vegetation & Foliage

  • Giant Luminous Mushrooms & Giant Gloomy Mushrooms generate in this cave
  • Normal-sized mushrooms generate on the surface
  • Radiant Vines grow from the ground
  • These plants all emit a small amount of light!

Food

Slimy Sewers (Slime Caves)

Structures

  • Lost Explorer Camps generate under frozen biomes (in ice caves) between Y=-30 and 20.
    • Lost Explorers trade you materials from the surface for things found underground
    • Because of a Minecraft bug, Lost Explorers do not spawn along with the structure. To spawn the Lost Explorer, interact with the Suitcase when holding an Emerald.

Other Blocks

  • Packed Ice Bricks can be crafted using Packed Ice. There is also Chiseled Packed Ice with a snowflake pattern!
  • Pebbles naturally generate here, except for Limestone variants. To craft more pebbles, simply put the respective block into a Stonecutter!

Experimental Toggles

  • You can find the toggles in World Settings under the Game section.
  • These toggles must be turned on:
    • Holiday Creator Features
    • Custom biomes
    • Upcoming Creator Features
    • Molang Features
  • The Wild Update, Vanilla Experiments, and Spectator Mode toggles are optional.
  • Backup your world first if you are turning on these toggles on an existing world!

Known Issues

  • The thick green fog from the Slimy Sewers, the yellow fog from the Limestone Caves and the blue fog from the Luminous Caverns & Ice Caves also appear on the surface.
  • Efficiency can be applied to Luminite tools but there will be no effect. This is a Minecraft bug.
  • Due to technical limitations, Radiant Vines, Dripping Slime, Sandy Roots and Dripping Icicles will not break when a supporting block is broken.
  • Blocks with a custom model (e.g. Radiant Vines & Dripping Icicles) do not get destroyed by water or lava and are not able to be waterlogged.
  • Pick Block does not work on blocks with a custom model. Get them from the inventory instead.
  • Some errors may show up when generating a world. These errors do not affect gameplay in any way and can be safely ignored. To turn off the error log, go to Settings > Creator > turn off “Enable Content Log GUI”.
  • World generation may take a bit longer when this add-on is activated.

Will the caves generate in my world when I add the addon or should I make a new world??
1
This addon seems so cool! I wouldn't mind some miniboss tho, I may get it!
1
Is the fog in swamp in desert from this? It’s really annoying
1
Yes. You can remove the fog by deleting the “fogs” folder in the resource pack. The fog is there to make caves more mysterious and add to the immersion.

Oh that was fast, ty

Can't wait to try it out! This will be epic!
1
Realms Support?
1
I downloaded it specifically for realms and was disappointed 😂
1
This is because experimental toggles aren’t present on Realms, which are required for the add-on to work. (I can’t do anything about this) You can try enabling them on a normal world first, then uploading that to your Realm.
1
making the world with experimental first does work. However it will fail to upload the pack unless you change the manifest file which his what I had to do
1
I have them on the world and have other addons that need them so idk
1
Can you make this for 1.17. Cas us in Edu minecraft are still in 1.17 so if you can do that Thanks but if you can't thats fine 😊💖
1
This add-on is not meant to be played on Education Edition. Please use the normal Bedrock Edition instead.
1
Mods like this sadly don't work because education edition doesn't have experimental toggles, and sadly I looked at the education forums and I don't think mojang will ever add experimental toggles to education edition.
1
all the blocks and items in the creative menu disappeared and the blocks all say updeate on them after the 1.18.30 update
1
had the same issue, but it should be fixed now
1
Hello. The new 1.3.1 update should have resolved this issue. Please update to that version. Thanks!
1
Hello everyone,

I am aware that Quicksand does not work in 1.18.30. This is due to technical changes made by Minecraft. Quicksand will be fixed in the next Beyond The Underground update.
1
This is awesome!!!
Can you please tell me a seed and the coordinates of the Luminous Caverns.
1
You can use the Mushroom Island seed in the seed picker (click on the arrow next to the seed box)
1
not compatible with realms
1
Unfortunately that is a Realms issue so I can’t do anything about it.
1
Didn't even know that this addon exist until the update it looks cool i will try it
1
Uma ideia pra tu que tal adicionar o estalagmit golem seria muito daora se adicionase
1
Stalagmite golems are a cool idea. Thank you!
