IMPORTANT MESSAGE BEFORE PURCHASING IN 2025 (Discord announcement):

Thank you all so much for the support of the Flying Navigation System plugin. I couldn’t have imagined it’d be so popular, but I’m very glad it’s been a useful tool (and made it into a few published games!). These past few years I’ve been very happy to provide support for the plugin, updating with new features and fixing bugs as well as stepping through troubleshooting. However, as I’ve planned for a while, I will be going on a backpacking trip from February 2025 until the end of the year. As such, support for the plugin will be going on a temporary hiatus. Because I won’t have a laptop with me, I won’t even be able to update the plugin to newer Unreal versions (beyond 5.5), which is rather unfortunate. I will see if I can maintain this minimum of support by tracking down a computer somewhere, but I cannot guarantee it.

With all that in mind, I’m by no means planning on abandoning the plugin. I still have not completed the project I built it for in the first place, so my plan once I get back is to dedicate more time to that project, which in turn will require improvements and new features in the Flying Navigation System.

For those looking for support next year, I have tried to make the documentation as comprehensive as possible, and the discord server has an extensive history of troubleshooting and application discussions. I will also still be around in January 2025 to help.

Cheers everyone,

Ben.

A feature-complete and easy to use Navigation System for flying AI agents. With full 3D pathfinding capability, this plugin is perfect for building advanced flying AI that can intelligently navigate under bridges, around cities and through epic space battles. This plugin is capable of pathfinding in large worlds, as processing time is concentrated in detailed areas. With multithreaded building and asynchronous pathfinding support, your flying AI needn't break the frame budget. The deep integration into the existing navigation system will get you up and running in no time.

The Flying Navigation System does not interfere with the default NavWalking navigation system, which can be used at the same time.
