OctreeX Pro is a highly flexible Blueprint-only plugin (See OctreeX++ for accelerated C++ version) for Unreal Engine that enables real-time spatial queries using an efficient Octree data structure.

OctreeX Pro builds on the base plugin (OctreeX) by adding advanced spatial query features like Box Queries and K-Nearest Neighbor (KNN) support – all Blueprint-only and still highly performant.
Ideal for developers needing flexible runtime searches in AI, simulations, or custom tools – without diving into C++.

OctreeX Pro will receive more updates down the line. If you only want a simple but fully functional Octree data structure, consider OctreeX and save a few bucks.

Features

• All features from OctreeX, plus:

• Perform fast Box Queries (AABB)

• Query k-nearest neighbors (sorted by distance)

• Optional per-entry radius for proximity queries

• Clean Blueprint API, no C++ needed

• Stack- and recursion-based query variants

• Visual debugging of tree and result matches

• Lightweight and easy to drop into your project

Use Cases

• AI perception zones, nearest object search, or trigger systems
