Kilt v20.1.11 (MC 1.20.1)

by BluSpring on Oct 22, 2025

Download

Changes

Remove dependency on Architectury API
Fully block Ice and Fire CE and The Twilight Forest Unofficial from loading with Kilt.
- Both of these mods would have terrible compatibility with Kilt and other mods, differ in behaviour from the original Forge versions, and are overall low quality. Use the official Forge versions of the mod instead, or if an official Fabric port gets released, use theirs instead.
- If you want to continue trying to use these mods anyway, use -Dkilt.allowBlockedMods=true. Here be dragons, you will not get support from using these versions.

Fixes

Fix Fowl Play birds not spawning with Kilt
Fix modded post-chain shaders not loading when Architectury is unavailable
Fix occasional double-registering of registry values
Fix Vanilla overlays not rendering when called by a Forge mod
Fix a bunch of broken injects that were missed
Fix compatibility with Potatoptimize (hopefully...)
Correctly support "0.0NONE" as an any version (why is this a thing?)
Fix JEI compatibility (#520)
Try to fix random NPE from part entities returning null in some places.

Forge Mod Fixes

Fix Create scroll values not functioning
Fix Create contraptions not rendering correctly

Kilt v20.1.8 (MC 1.20.1)

by BluSpring on Sep 16, 2025

Download

Changes

Improve error message when failing due to missing Sodium, invalid Flywheel, etc.
Disabled risky optimization with armor
- This fixes GeckoLib armor not animating correctly or crashing if implemented by a Forge mod (#451), however it also reverts the performance issues with MCreator mods with custom armor such as Apocalypse Now.
Reimplement Night Config Fixes via Kilt. You can now play with Kilt and Prominence II.
Added error on startup with certain mods when missing ThreatenGL. (#132, #364, #418)
- This allows mods such as Simple Clouds and Bigger Reactors to work.
Added sanity check to warn if any mods are repackaging Forge classes.
- This makes it significantly easier for us to debug what mod may be causing crashes with Kilt, as a shocking amount of Fabric-ported mods seem to repackage Forge classes, resulting in incompatibilities like these.

Fixes

Work around weird IllegalAccessError crash on block entities
- This was caused by Fabric mods implementing a private method that was similar to the Forge one, resulting in a crash when Kilt tried to call it.
Try to fix crash with Antique Atlas 4 (#415)
Work around crashes relating to Porting Lib
- This fixes crashes with mods such as Zenith.
Fix crash with Snow! Real Magic! (#381)
Try to fix weird refmap crash in mixin remapper
Fix incompatibility with InvMove (#438)
Fix crash between Supplementaries, some Fabric mods, and some Forge mods
Fix leaves not being shearable (#460)
Fix crash with Farmer's Delight Refabricated
Fix deferred effects crash with food

Forge Mod Fixes

Fix crash with Oreganized (#284)
Fix GeckoLib event crashes when required by a Forge mod (#421, #459)
Fix crash with ReTerraForged
Fix crash relating to LoadingModList. I forgot which mod it was that broke with it.
Fixed Forge mod mixin crash when there exists a blank entry
- Why does this not occur on Forge? I have no idea.
