Navigation map synchronization error

Catalin

Full error text E 0:00:06:0757 sync: Navigation map synchronization error. Attempted to merge a navigation mesh polygon edge with another already-merged edge. This is usually caused by crossing edges, overlapping polygons, or a mismatch of the NavigationMesh / NavigationPolygon baked 'cell_size' and navigation map 'cell_size'.
<C++ Source> modules/navigation/nav_map.cpp:845 @ sync()

The only overlap i can find is in the Baked Navigation Mesh on the edges like in the picture, why is Godot doing this and how can i fix it ? And is this error critical since it's red? My AI's are still working and the level appears to be running fine

Catalin can you not create your own path mesh? in blender?

Catalin

kuligs2 i was hoping not to, how em i going to account for like 1000 objects on the map ?

Catalin did you check the source? <C++ Source> modules/navigation/nav_map.cpp:845 @ sync() https://github.com/godotengine/godot/blob/61adafae2f9dace1f094b89ab2aceebd114e1c01/modules/navigation/nav_map.cpp#L845

It sucks that you cant select 4.1.1. source, they have 4.1 branch i guess they might have updated this at some point. This is a good opportunity to learn to fork a source, build it yourself use, until it break and then you can figure out stuff more precisely. But in general its the same function. Maybe this gives you some inkling why it does that.

kuligs2 Thx for the reply, but i am in no way qualified to look into source codes and fix anything, i can barely wrap my ears around GDscript and doing things correctly.

I upgraded to Godot 4.4, deleted the nav meshes and rebaked, no luck, same problems.

I'm back to 4.1. I packed the game for Windows and it runs fine with the error unfixed and the AI seems to be ok, so im just going to ignore it and focus on finishing the game.

Catalin did you try the fix in this post? https://forum.godotengine.org/t/navigation-mesh-not-properly-working-when-i-use-more-than-one-navigationregion3d-that-have-almost-identical-meshes/50914
