Highlights

mc1.21.4 beta

mc1.21.4 beta is missing Enhanced Block Entities (mod is updated but has bugs) and leaf culling. Also missing Animatica, CIT Resewn, and FabricSkyboxes+Interop. Other than that, it should be pretty stable.

Missing mods
  • Enhanced Block Entities
  • Sodium Leaf Culling
  • CIT Resewn
  • Animatica
  • Fabric Skyboxes + Interop

Updated mods

Most of the mods in the modpack have been updated. Fabric loader has been updated.

Simulation distance 5->8

Improves vanilla parity with mob spawning. This should not matter if you play on servers. If you play in single player and need the most performance, you can change it back.
