Using the render mesh as navmesh

Hi,

I want to know if I can use the mesh in MeshFilter also as the NavMesh?

I want to have 1 navmesh tile for 1 unit and it takes a lot of time in the runtime to create it.
My levels are procedural and I need exact accuracy so the agents are always on the surface graphically.

Is it possible? Thanks

AFAIK this is currently not possible.
