Ok so I can use the entrance to my home easy enough, but when i try to use the door at the back that leads to the porch I load dead on the ground. BTW I'm using Dragon reach exterior layout on my home, and made surte to use the INT porch piece because it had collision on it. I also made sure to add a navmesh triangle right under my dorr portal marker.

Do i need to add navmesh everywhere on the porch or just under the door teleport marker?

Bump

navmesh - or lack of - should not kill a PC (no navmesh does give NPCs big issues).

Have you checked that the teleport (yellow/orange) boxes are properly aligned (exterior/interior) with the ground surface? (Is it underground, or way above ground level, in the exterior cell?)

Can't think of much else ...
