Fluxion

0.22.0 — Minecraft 1.21.1

Minecraft 26.3 and 1.21.1 · Fabric and NeoForge · Java 25 / Java 21

Fluxion now runs on Minecraft 1.21.1 as well — with the same content, and with mods that never came out for 26.3.

New

• Minecraft 1.21.1. Four files now: 26.3 and 1.21.1, each for Fabric and NeoForge, from one codebase — every future update reaches both versions together. On 1.21.1 you need Java 21, Fabric Loader 0.20.1 with Fabric API 0.116.17 or NeoForge 21.1.265, GeckoLib 4.9.3 and TerraBlender 4.1.0.8.
• Blocks from 26.x on 1.21.1. Where Fluxion builds on things 1.21.1 does not have, the 1.21.1 files bring their own that behave as in 26.3: pale oak and poplar wood (full sets and saplings; poplar leaves come yellow, orange or red), short and tall dry grass, pale moss with its carpet and hanging moss, the copper nugget, copper tools, copper armor and copper horse armor. They grow and generate where the mod puts them on 26.3 and fit the same recipes.
• Dappled Forest and Pale Garden on 1.21.1. All of this can now be found in survival just as on 26.3: poplars in three colors grow in the Dappled Forest, pale oak with pale and hanging moss in the Pale Garden (both biomes generate where they do on 26.3 — on cool dry plains and on humid dark forest plateaus), dry grass in deserts and badlands, copper horse armor lies in the same chests of dungeons, temples, fortresses, End cities and weaponsmiths, and the wandering trader sells pale oak and poplar saplings and logs, pale and hanging moss and dry grass, as on 26.3.
• Mechanics — a branch for Create (1.21.1, NeoForge, Create 6.0.10). The Stream Wheel turns shafts with your chunk's flux (twice as fast where a Gauge Stone speeds the flux); the Windlass gives shaft power to the Stamp Mill, the Molder, the Sluice Box and the Pump; the Crucible Stirrer sinks solids even over a gentle heat; the Drip Tap fills vials on belts and depots, and the Decanting Trough pours them back into vessels, the Crucible and the Gyre. The Mechanical Arm tends Confluence plinths, the Crucible and workshop devices; an Ember Shard superheats a blaze burner; fans blowing through Orbs wear, mend, dry, set and rinse blocks; Create's machines crush, press and mix the mod's materials. Diviner's Spectacles work as engineer's goggles, display boards show chunk flux and held currents, six Ponder scenes and a Codex tab with 13 entries explain it all.
• Content branches on 1.21.1: Energistics (Applied Energistics 2 19, NeoForge), Spirits (Occultism, both loaders) and Kitchen of Currents (Farmer's Delight — on 1.21.1 on both loaders: the official mod on NeoForge, Refabricated on Fabric).
• Mods that exist only on 1.21.1:
  • EMI — its own pages for every machine of the mod, currents as their own stacks (with favorites);
  • WTHIT — the same lines as Jade: distillate, heat, murk, currents;
  • Accessories — slots for the mod's amulets, rings and belts; Diviner's Spectacles on the face look as in the helmet;
  • Embeddium (NeoForge) — the Mod Graphics page in its video settings;
  • ModernFix — tested alongside the mod.
• Trinket slots on Fabric 1.21.1 come from Trinkets 3.10 (Trinkets Updated has no 1.21.1 build), on NeoForge — from Curios (and Accessories).

Fixed

• Overworld rain started and stopped about five times too often on 26.3: the mod's worlds with their own sky also moved the weather clock.
• Hanging on a Grapnel for more than four seconds got you kicked from a dedicated server for flying.
• The light of strong moments (the sky darkening over a Breach) was measured from the player instead of the camera: with camera mods the sky went darker than it should.
• Items brought back by the Recall Circle could be picked up by any player standing nearby; now only by their owner.
• When the Spillover was stopped by command, a player riding it could be kicked from a dedicated server for flying while the stream faded.
• On NeoForge 1.21.1 the server kicked players for flying during any slow fall longer than four seconds (a NeoForge 21.1 bug that also hits the game's own Slow Falling): the mod restores the game's check there.

What to do

• Pick the file for your game version and loader — the name says both: …-fabric-26.3-0.22.0.jar, …-neoforge-1.21.1-0.22.0.jar.
• On 26.3, replace the 0.21.1 jar with the 0.22.0 one: worlds carry over, the required mods stay the same.
• A world cannot move between 26.3 and 1.21.1: the game does not open worlds from a newer version.
• The branches need their mods: Applied Energistics 2 19 (NeoForge), Occultism (with what it asks for — Modonomicon, SmartBrainLib), Farmer's Delight, Create 6.0.10 (NeoForge 1.21.1).

Known limits

• Create has no build for 26.3 and none for Fabric 1.21.1: there the Mechanics items stay in the game with a red «Requires mod» line. Applied Energistics 2 has no Fabric build for either version.
• EMI (official), WTHIT, Accessories, Embeddium and ModernFix have no 26.3 builds — they work on 1.21.1 only. Oculus has no 1.21.1 build: shader packs on NeoForge 1.21.1 go through Iris with Sodium.
• Small differences on 1.21.1: the pale moss carpet has no side walls, dry grass and pale moss have no ambient sounds, copper armor sounds like iron when put on, poplars grow fancy-oak crowns.
