I’m very out of the loop for what is the current best navigation system within Unity. I was looking through the manual and I see Legacy Navigation that explains how NavMesh works. But because it says legacy, I’m assuming there is a newer system that is either better or more commonly used, is that accurate? If there is a newer system, what is it called?
The Unity team is currently working on navmesh (thread above this one). I for one use Emerald AI exclusively for all projects. EAI is insanely good, been around as long time, and can be modified to your needs (API included). Been using it for years, never had any problems at all.

Thank you for sharing Emerald, I will definitely check it out. So when talking about NavMesh, are you saying Unity is currently working on making it better? Or do you mean they working on a replacement?
“best” is subjective

The latest built-in NavMesh package is good.
Aron Granberg’s A* is best.
Everything else is noise or roll your own.

where do I check out the new navmesh system in place? I’m not sure where to read the newest features, is it in a different location than the legacy navmesh section of the manual?

Thank you very much, I have some reading to do! I have been using a custom AI that I wrote myself but I think its worth exploring navmesh components…thanks again for the feedback everyone who responded.
