Mod Structure Layout Optimizer

Structure Layout Optimizer

Structure Layout Optimizer is a performance focused Java mod that speeds up the generation of Jigsaw structures and NBT pieces without intentionally changing their appearance. It is designed for a Minecraft server and singleplayer worlds, with support for Fabric, Forge, and NeoForge across several Minecraft versions.

Its optimizations reduce expensive structure intersection checks with a BoxOctree, skip impossible Jigsaw connections, avoid repeated template pool work, and load large NBT pieces more efficiently by filtering positions early. An optional configuration can deduplicate weighted templates for extra speed, although this may alter structure layouts for a given seed. At BoxToPlay, we recommend it for structure heavy modpacks and servers.
