"Holes" in the Nav Mesh

Hey Kajemyaka,

Have you tried to rebuild your paths after deleting the sprites?

Also, check in Project Settings > Navigation Mesh to see if it's set to Force Rebuild paths:

There's also a setting for this in the RecastNavMesh actor in your level, accessible in the Details panel while it is selected.

Hope that helps! Let me know if rebuilding paths doesn't resolve the issue.

A) have you tried rebuilding your lighting b) have you tried going into the landscape mode and selectiong and then adding squares back in?

It looks to me like shadows from previous objects that got deleted and the lighting was never rebuitl.

Hope this helps Don't forget to accept an answer that best clears your question up or answers it so when the community finds your question in the future via search/google they know exactly what you did to fix it/get it going.

For anyone struggling with this, rebuilding paths wasn't enough for me.

To fix that, I also found the interesting object on my map, which is generated by NavMeshBoundsVolume, named RecastNavMesh-Default. You can see it on the screen. Simply delete it if there is some weird hole in the NavMesh and rebuild the paths/geometry as in another answer.

In that RecastNavMesh-Default, I also found an option called "Draw Path Colliding Geometry", which showed me what was causing the problematic hole. Indeed, there was a collision in the spot, but no object to cause that collision. The collision was outdated as I moved the object slightly above it.

Have a good day!
