Material Rule Compiler
A vanilla worldgen optimization mod. Works by compiling material rules to bytecode and optimizing material rules.
Quick answer
Which Material Rule Compiler release should I use?
Material Rule Compiler 1.1.4+26.3 targets 26.3 with Fabric, Quilt. Do not install it on the client. It must be installed on the dedicated server. All 1 required mods have matching files.
Where it goes
Is Material Rule Compiler required on the client, server, or both?
Do not install it on the client. It must be installed on the dedicated server.
This file is marked server-only.
What else does Material Rule Compiler 1.1.4+26.3 need?
1.1.4+26.3. Change the file and its required mods may change too.
Install ZConfig first. We found matching files for this game-version and loader setup. 4 come through another mod in the chain.
4 extra mods were pulled in by other dependencies. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Material Rule Compiler add?
Material Rule Compiler is an experimental worldgen optimization mod, that works to improve surface builder times by compiling material rules into static functions.
Does the mod change world generation? The mod maintains vanilla parity, including with any datapacks. Do keep in mind, Vanilla non-determinism.
Can I use custom worldgen mods with this? Yes, the mod will fallback to normal execution where it encounters modded content. Though, it is possible to have mod incompatibilites. I do test against major worldgen mods like terratonic etc.
Note Fast Noise is needed for optimal speed
Material Rule Compiler is part of Reverie Projects, check out our other mods as well.
How does this mod work?
Material rule compiler compiles material rules into classfiles using asm library, optimized for every unique set of biomes. It also reduces allocations for random splitters in material rules and predicts biomes for material rules.
How fast is it?
About 30-40% decrease in surface builder execution times.
