Creating a Navmesh manually

Is it possible to manually create the nav mesh? The nav mesh generates in kind of odd ways (for example, creating angles when there should be straight lines). For the most part it doesn’t affect the gameplay, but it can become an issue in certain situations. It would be better for this particular game if I could have a perfect grid of navigation areas that connect to each other when in proximity.

Yes, it’s possible.

In fact, there are assets in the Marketplace that do this in three dimensions (Unreal only allows 2 in its default).

I’d rather do it myself, but I’ll check out the store and see if I can learn something from those plugins. Do you know what they are called?

You can always tweal the navmesh settings in project settings so it covers all the walkable path knstead of a rediced one and modifying with nav mesh modifers and stuff
