When are navmeshes loaded into memory/Any way to unload them?

Hi,

Can't seem to find any particular info on this, wondering if a scene's navmesh is automatically loaded into memory on scene load, and if so, what the correct way to "unload" a navmesh is.
At the moment, I want my server instance of my game to be the only one calculating the pathfinding, so if possible, I'd like to avoid having all clients load in an unused 200MB navmesh.

Cheers

 

Yes currently the navmesh data is stored 1-to-1 with the scene. As the scene is (un)loaded so is the navmesh.
If you want a server only to access the navmesh data -- one option could be to have the navmesh baked into a separate scene which (on the server only) is loaded using LoadLevelAdditive.

 

Hmm ok, so would there be any way for me just to create an empty scene and tell that scene to use the navmesh I baked in my main scene - eg. renaming files/anything like that? Or would I have to create a duplicate scene, bake the navmesh in that, then delete everything in it to get a scene with just the navmesh?

 

Depends - you could copy the scene - bake navmesh and remove scene contents.
(although i would - dicouraged as it may be - make an empty scene and make it point to the navmesh data using a text editor).

 

Just getting around to this now - not exactly sure how I go about pointing to the new scene with a text editor - can't seem to find anything obvious in either the meta/scene files of the navmesh or the scene?

 

@Jakob_Unity Also, is any of this changing in 5.2? Really running into a huge roadblock with pathfinding at the moment, the inability to decouple the navmesh from the scene is creating some big issues (couldn't seem to find how to hack it with a text editor like you suggested) , paired with the fact that I'm running into a pretty serious limitation with the A* pathfinding project that also makes it unusable.
