How to build navmesh at Runtime without lag

[felixklein460]

I have a problem:

When my bomb hits the terrain, it creates a hole, and everything works, but the NavMesh still uses the old terrain. I tried to bake the terrain when the bomb explodes, but it freezes for 3 seconds and then continues. I couldn’t find any solution. I don’t understand why it seems like no one has tried this; it’s such an important function to update during runtime.

Thanks. Regards

What about using a Task in order to avoid blocking the main thread?

Task.Run(() =>
       {
           // Represents a Performance Intensive Method like some pathfinding or really complex calculation. This code won't run on the Main Thread!
           float value = 0f;
           for (int i = 0; i < timesToRepeat; i++)
           {
               value = math.exp10(math.sqrt(value));
           }
       });

Baking the navmesh is done by Unity function, putting it in a task doesn’t work. It’s already multithreaded, just not in the way that it works properly.

How big is your navigation mesh?
A solution would probably be to make it smaller and work with different nav mesh surfaces, which you need to stitch together with NavMeshLinks.
