Frequently asked questions

What does the Structure Layout Optimizer Mod do?
It improves the performance of Jigsaw structure generation by replacing inefficient VoxelShape intersection checks with BoxOctree-based calculations. This reduces validation time and makes large, recursive Jigsaw structures generate more smoothly.
Why is vanilla Jigsaw structure generation slow?
Vanilla verifies structure piece intersections by comparing all VoxelShape vertices, which causes noticeable delays in large or complex builds. The mod replaces that slow check with a faster BoxOctree system.
How does the mod replace vanilla's VoxelShape checks?
It swaps the standard VoxelShape for a dummy version containing a BoxOctree. That BoxOctree only checks intersections against neighboring structure pieces instead of comparing every vertex.
What is the main performance benefit of using a BoxOctree here?
It limits intersection checks to nearby structure pieces rather than all pieces, cutting down on lag during generation. This makes massive, recursive Jigsaw structures generate more smoothly.
