Planned

Optimized Cushions

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

Evidence

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

What it needs from Kiln

Mixin
net.fabricmc.fabric.api.client.event.lifecycle.v1.ClientEntityEvents
net.fabricmc.fabric.api.client.event.lifecycle.v1.ClientEntityEvents.Load
net.fabricmc.fabric.api.client.event.lifecycle.v1.ClientEntityEvents.Unload
net.minecraft.client.renderer.extract.LevelExtractor
net.minecraft.core.SectionPos
net.minecraft.world.entity.decoration.Cushion
FabricLoader.isModLoaded()
Minecraft.execute()
Minecraft.isSameThread()
Minecraft.levelExtractor
BlockPos.containing()
Direction.fromYRot()

On the roadmap: Minecraft's libraries and client API (0.2), Code next to data (0.3), Mixin (0.5)

In the author's words

Optimizing cushions on client and server

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file optimizedcushions-fabric-mc26.3-1.2.0.jar. The scan reads the mod's classes; it does not run them.
