Take navigation in your Unreal Engine projects beyond flat surfaces. The Pathfinding 3D Plugin enables advanced pathfinding in full three-dimensional space, ideal for flying AI, drones, underwater creatures, or any scenario where movement isn’t restricted to the ground.
Key Features
3D Navigation Grid – Calculates paths in all three dimensions, not just on a plane.
Asynchronous Pathfinding – Optimized for performance with multithreaded algorithms to minimize game thread impact.
Obstacle Detection & Avoidance – Dynamically accounts for obstacles in 3D environments.
Flexible AI Integration – Works seamlessly with Unreal Engine AI Controllers, tasks, and behavior trees.
Data-Driven Settings – Configure navigation parameters using data assets for modularity and easy tuning.
Indoor & Outdoor Ready – Supports complex levels, from tight corridors to vast open spaces.
Highly Optimized – Designed to minimize memory usage and runtime overhead.
Use Cases
Flying AI (drones, aircraft, birds, insects)
Swimming AI (fish, submarines, underwater exploration)
Sci-fi projects (space navigation, robots, zero-gravity environments)
Complex traversal across multi-level architecture
Why Choose Pathfinding 3D?
Most navigation systems in Unreal Engine rely on 2D NavMeshes, which work well for ground-based characters but fall short when you need AI that can navigate in three dimensions. Pathfinding 3D removes this limitation by introducing a volumetric navigation system, allowing your AI to calculate routes through the air, underwater, or even in zero-gravity environments. This makes it the perfect solution for modern games and simulations where movement isn’t confined to a plane.
Beyond flexibility, the plugin is built with performance in mind. The pathfinding process runs asynchronously, ensuring heavy calculations never block the game thread. Combined with lightweight memory usage and obstacle-aware pathfinding, your AI will remain responsive even in complex environments. This optimization makes Pathfinding 3D suitable not only for prototypes but also for large-scale productions that demand reliability and efficiency.
Pathfinding 3D is developer-friendly and extensible. Its data-driven design allows you to fine-tune navigation settings through assets instead of hard-coded logic, making iteration faster. It integrates seamlessly with Unreal Engine’s AI Controllers, tasks, and behavior trees, so you can drop it into your existing systems without rewriting core gameplay. Whether you’re building flying drones, swimming fish, or futuristic robots, Pathfinding 3D gives your AI the intelligence it needs to explore the full depth of your worlds.
