Dynamic Levels & Navmesh

Question

I'm creating a level by placing prefabs side-by-side (e.g. making a long hallway with a series of floor objects). However, this is being done dynamically... the level is only built at runtime.

I was hoping to use Unity's pathfinding - the prefabs could still be marked NavMesh Static, because they won't move after the initial placement - but it looks like NavMesh can only be baked into the scene, not attached to a prefab. Is Unity's NavMesh even a possibility for me here? If not, are there recommended pathfinding solutions for dynamic levels on the Asset Store? Or do I just have to figure out my own custom pathfinding solution?

Hey guys, I found a workaround to this proble, in the last post on this thread:

http://forum.unity3d.com/threads/122545-Problem-with-NavMesh-and-Asynchronous-load

You need to save your navmesh prefab in a scene by itself, then load it in (non additive), but set the game objects in your scene to "Dont destory on load".

Its kinda hacky but it works for now. But overall, I really wish Unity would extend the NavMesh features.

I have exactly the same problem :/. I can't understand why it's not possible to prefab the Navmesh to reuse it! It's like a basic feature to me. The lightmap baking is working fine with prefabs so I expected that the Navmesh baking was at least working the same way !

In fact, I have to revert back to previous solutions like http://angryant.com/path/

I hope that Unity 4 will enable that feature.

Gah. Hoped they fixed it... Well, they have to force us pay money for assets right? So go and buy Aron's asset for $100 :-/
