Nav question - make pawn pass thru nll nav mesh?

hello, as seen in attached image…

i want my pawn, that has floating pawn movement… and is LOCKED to an axis… therefore can go only in straight lines…

i want the pawn to be able to pass thru navmesh that has static meshes…

the actor is already set to ignore the static mesh, and also with the static mesh to ignore the actor…

but the actor cant pass thru because the navmesh has been updated by the static mesh…

is there anyway i can make the pawn to be able to pass thru?..

do i need to create another navmesh bounds that is being used ‘exclusively’ by the pawn?..

wont that be too expensive to make?.. double nav mesh… yet being used by only 1 pawn actor…
