RVONavMesh serialisation

Hi,

I’ve added RVONavMesh and RVOSimulator into my scene which contains a huge terrain. Recast nav mesh generation is all fine. However, when I run the game, it takes forever to load the scene as it seems to be adding obstacles and building obstacle kdTree.

Is those nav mesh obstacles not serialised into the scene?

Has anyone done anything similar to improve the runtime startup performance?

Any hint would really help. Thanks.
