Alex Caves Dimensions Portals

Adds fully configurable portals for Alex’s Caves dimensions in Minecraft Forge 1.20.1.

Unlike traditional worldgen mods, this mod keeps the Overworld clean by placing each cave biome in its own separate dimension, accessible through custom portals.

Perfect for exploration-focused modpacks and multiplayer servers.

Shader Compatibility Notice

Because Alex’s Caves uses custom visual effects, fog, lighting, and atmospheric rendering, certain shaders can cause visual glitches or broken rendering inside the cave dimensions.

For the best experience, it is recommended to play without shaders while exploring these dimensions.
