Structure Layout Optimizer Mod (1.21.7, 1.20.1) – Optimize Jigsaw Structures
Structure Layout Optimizer Mod (1.21.7, 1.20.1) improves the performance of Jigsaw structure generation in Minecraft by replacing inefficient VoxelShape intersection checks with more efficient BoxOctree-based calculations.
In vanilla Minecraft, structure piece intersections were verified by comparing all VoxelShape vertices—causing noticeable delays, especially in large or complex builds. This mod replaces the standard VoxelShape with a dummy version containing a BoxOctree, which only checks intersections against neighboring parts. The result? Drastically reduced validation time and smoother generation of massive, recursive Jigsaw structures.
Features:
- Replaces vanilla’s slow VoxelShape checks with a BoxOctree system that only compares nearby structure pieces—cutting down on lag during generation2.
- Skips unnecessary checks for Jigsaw Blocks that are blocked or facing boundaries, saving CPU cycles.
- Filters out irrelevant positions early when loading large NBT files, improving load times for massive structures.
- Reduces redundant calls to block properties and simplifies NBT data parsing for Jigsaw Blocks.
- Avoids rechecking duplicate structure pieces with high weights, and optionally deduplicates the pool for even faster generation (at the cost of seed layout parity).
- Swaps heavy

lists with lightweight palettes that shrink memory usage when structures aren’t actively generating.
