Is there a certain trick to making a NavMesh

I'm trying to create a NavMesh from my game map. In Blender, I copied all of the faces I want to be navigable by the Vehicle. Then I export it as a GLTF. Does it matter that the faces are double sided?

In many cases, NavMeshes are auto-generated. This process does not output double sided faces. I'm afraid it would not make sense doing this. The loader would create a navigation mesh with the double amount of convex regions which is definitely not what you want.

How do other people generate nav meshes?

We've done this with Blender 2.7 so far. Unfortunately, the latest Blender version does not support this feature anymore. As a long term goal, we want to introduce a nav mesh generator in Yuka, too.
