Iris Caves
- By
Makes Alex's Caves work with your shaders — biome fog, the Luxtructosaurus red sky, Deepsight, and fixes for its invisible mobs and projectiles.

What's new
1.1.1 — Minecraft 1.21.1 / NeoForge
First 1.21.1 release. Same mod, same features, ported to NeoForge and Iris (instead of Oculus).
Requirements: Minecraft 1.21.1, NeoForge 21.1+, Iris 1.8.14+ (with Sodium or Embeddium), Alex's Caves 2.0.10 + Citadel.
Feature-identical to the 1.20.1 build — the shader-patching engine and every injected GLSL hook are the same code. What changed is the plumbing:
- Rebuilt on NeoForge 21.1 and Java 21.
- Targets Iris directly rather than Oculus.
- Uses NeoForge's render types, registry and effect APIs (the render-type visibility fix works the same way).
- No more mapping workarounds — NeoForge runs on official Mojang mappings, so the entity-renderer hooks are simpler and less likely to break on a game update.
Everything verified against the actual Iris 1.8.14 and Alex's Caves 2.0.10 jars before release: all render type hooks, the uniform bridge and the boss-state hook are present and unchanged.
> Configs and generated _iriscaves packs carry over — nothing to redo if you're coming from 1.20.1.
