Encountering issues while using 3D navigation

Godot Version

4.5.1

Question

When using 3D navigation, I found that the monster would walk against the wall, which is not what I wanted. Is there any way to make the monster walk in the middle

Is the navigation mesh generated from the NavigationRegion3D with default value? If yes, you might want to change the NavigationMesh properties for the sampling partition type from Watershed to Layers which is better for tile- or grid-based map.

Also change the properties of the NavigationAgent3D for path post processing from Corridorfunnel to Edgecentered which make the agent move at the center of the tile or grid.
