NullReferenceException in CalculateWorldBounds

[AbstractFlame]

I've clicked on Rotate Surface to XY, have an agent and 2 tilemaps with NavMeshModifier.

StackTrace:

NullReferenceException: Object reference not set to an instance of an object

Hello, @AbstractFlame

NavMeshSurface2d - is obsolete, you should try extensions system with NavMeshCollectSources2d.
Or wait until it fixed\updated

[AbstractFlame]

Thank you for the fast answer :)

First of all: Thanks to h8man for your work!

I have the same Problem when Baking with NavMeshSurface ( i followed your current manual):

@RB3009

I don't know how it happen, I need test project to see it myself and debug lines

Bump.

@RB3009 @h8man Hi! Did you manage to fix it? I have a similar problem and I will attach some screenshots so you can better understand the error.

More context:
I set up a grid with a tilemap and now when I run "Bake" I get this error. But the error occurs only if I use "Use Geometry": RenderMeshes in the case of Physics Colliders - everything works fine

Hi, im having the same problem



Should I use colliders for now? Or is there easy fix for that

[GaLzZy]

Anybody fixed that problem cause I have the same issue

[painh]

I had the same phenomenon when I put the collider on the tile.

Resolved by changing the Use Geometry option to physics colliders in the navigation surface.

As of april 2025, the issue doesn't seem fixed but this worked. I still need to make some adjustments to get the proper nav surface but at least i can bake.
For a bit more context, it was working just fine then I added a non-walkable nav modifier as per usual, tried to bake and encountered this issue. Even after disabling/removing the nav modifier and closing/reopening unity i couldn't bake anything at all anymore.

Here's what worked for me: set Use Geometry to physics colliders in the navigation surface, then reimport the navmeshplus package in Unity Package Manager from github repo.
