RuntimeNavMeshBuilder: Source mesh xxxxxxxxxxxxxxx does not allow read access.

Unity Engine

“This will work in playmode in the editor but not in the player.”

I bought an asset pack, but when i try to use the prefabs in a scene I get that error for every single one. Apparently all the models do not allow read access. I cannot for the life of me figure out how to enable read access, why it would be disabled by default, or why I am running into this problem when googling suggests that nobody else has.

Any help would be greatly appreciated.

You should be able to select the asset and on the Model Importer settings there should be a check box ‘Read/Write Enable’.

I bumped into this error message and even though my models were enabled for read/write and static was ticked off
the problem still persisted.
So I tried In the Inspector / on NavMeshSurface panel setting the Use Geometry option to Physics Collider.
Now it works.

I’m getting this a lot. Problem is, I don’t want the meshes to be readable, nor do I want them to be considered for navigation. How can I ensure the runtime Navmesh builder ignores them?
