Material Rule Compiler

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.
