About this Mod

Retro Caves

Do you want that old cave nostalgia? Don't like the weird caves added in 1.18? Well you're in luck, this datapack removes them! There are still the new 1.18 cave biomes and ores, but none of the gigantic, large noise caves from 1.18. This datapack works with the Large Biomes and Amplified Presets as well.

Compatibility Notes:

This is not compatible with anything that changes the terrain, like Tectonic, as noise caves and terrain are defined in the same place. This means that this only intended for the default generation. Additionally, anything that creates its own carver caves will not have those caves removed.

"I wish I could remove all caves, not just change them..."

Frequently Asked Questions

Retro Caves server crashes on startup – what to do?

Most common cause: wrong datapack version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (26.1). You can switch loaders with one click in the panel.

Is Retro Caves compatible with datapack and fabric and forge and neoforge and quilt?

Retro Caves officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 26.1, 1.21.11, 1.21.10. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Retro Caves – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Retro Caves consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
