Worlium

Worlium replaces all vanilla cave generators with a Worley-noise-based carver modeled on the classic Worley's Caves mod by fluke. The Worlium carver produces sprawling, winding, interconnected tunnels; from a gameplay perspective, the underground becomes a massive, labyrinth-like cave system that feels simultaneously claustrophobic and expansive.

The mod ships for both Fabric and NeoForge through a shared common module that implements the carver as a custom DensityFunction (worlium:worley_caves) plugging into Minecraft's modern worldgen pipeline. Under the hood, the density function samples a seeded 3D Worley F1/F3-edge cellular noise warped by a 2D Perlin displacement field, applies a depth-scaled warp amplitude so caves become more chaotic closer to bedrock, and eases the cutoff back toward solid near the surface to avoid carving terrain into shreds. The result is a drop-in cave overhaul that preserves the visual identity of the original Worley's Caves while living entirely inside the 1.18+ density-function framework.

Features

• replaces all vanilla caves with a Worley noise-based carver
• custom aquifer logic (prevents caves from being flooded with water)
• first-class support for Moderner Beta's world preset
• increased diamond rarity
• removal of diorite, andesite, and granite blobs

Known Issues

• when close to aquatic biomes (oceans, rivers, etc) the carver will occasionally terminate with a flat stone wall
• the current aquifer removal logic uses biome tags, which works pretty well but is horrible for compatibility with other worldgen mods

Compatibility

• Moderner Beta: supported
• Terralith: probably fine
• CliffTree: good
• Tectonic: suboptimal
• Cave Overhaul: no
