This plugin provides a 3D dynamic pathfinding system for use with Unreal Engine 4. This system was first developed for my game DoN The Nature Game and I decided to make a plugin out of the navigation module as a gift to the Unreal community.

It's primarly designed for Flying AI creatures based in dynamic or procedural worlds that need to solve complex pathfinding tasks and other behavior that cannot be readily solved by Unreal's native AI navigation system and also for maps that are too complex to be solved by simple ray-tracing/sweeping heuristics or by waypoint systems.

Where possible, I recommend that you use Unreal's native AI navigation or simpler navigation strategies; use this system when the more conventional strategies cannot solve your pathfinding usecases.

The plugin provides the following:

• Navigation Manager actor for configuring the system
• "Fly To" behavior tree node that can be readily dropped into your behavior trees
• Nodes for managing dynamic collision and pathfinding in your scene.
• A pathfinding API that advanced users can use for custom navigation queries from either Blueprints or C++

I've created a sample project for you to quickly test the system and understand the different usecases it covers.
