NavMesh

having real issues trying to get my nav mesh to run up stairs onto a platform. Is it best to adjust settings within the project settings or Recast element within the outliner?

Should the NavMesh Volume be scaled to the height of the raised platform with stairs having simple box collisions?

Problem is I can only check in Vr once my scene has been packaged.

Any tips? Also get large triangles showing on NavMesh.

Thanks
