Gridmap Navmesh Missing Texture

Godot Version

4.2

Question

After reloading my project, my navmesh looks like a bunch of magenta squares, much like a Source Engine missing texture without the black. At first I thought it was only visual, but it appears the path my nav agents take is based on the magenta squares. Any help would be much appreciated.

Turns out trying to attach a navmesh to individual tiles is a bad idea. For anyone stumbling upon this problem in the future, make the Gridmap for your floor tiles a child of a NavigationRegion3D and bake when changes are made.
