If someone still has this problem. First be sure you have your navigation view on, pressing P. Then scale up your NavMeshBoundVolume, cover up a good area from of your StaticMesh. If after that no green or red area appears, the problem is that your Static Mesh has no collision primitives. On the Static Mesh’s editor, check if you have Collision Primitives > 0. If not, you can add collision boxes on the collision menu, or redo your static mesh in your 3d modeling program and add it there.
Another option, in the case you don’t want to add collision on your static mesh, is to add BlockVolumes boxes on your level, scale it properly and make sure it’s within the high level of your NavMeshBoundVolume, that should do the job!!
