PackForge - Optimized Resource Pack Loading Time

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): PackForgeFabric did not start: java.lang.NoSuchMethodError: 'boolean net.fabricmc.loader.api.FabricLoader.isDevelopmentEnvironment()'.

In the author's words

Faster resourcepack reloads and atlas overflow recovery for large resource packs.
