Navigation Mesh Not Applying to Static Mesh


So I have made some static Meshes for Floors and Walls, When Applying the Navigation Area, it is applying to the BSPs but not the static meshes.

As seen in the 2nd Screenshot when I put a BSP on the same level as my Static Mesh the Nav will update to that.

Is there something I have missed or have done wrong ?


First of all make sure your meshes have collision representation.

I believe they already have them when imported as my character doesn’t fall through the floor.

I have also selected remove collision, tested and my character falls through the floor as anticipated. Added a simple box collision and the character doesn’t fall through the floor but the Navigation is still the same.


There’s a bug in updating navigable collision when you change it in the static mesh editor. Try adding simple box collision, saving and restarting the editor.
