North Marker

How do I make the compass of the interior match the exterior?

You have your house, dungeon, etc. and the link set up to the worldspace, but when you enter your house, etc., you note that the compass does not match the compass before you entered.
In the images below I enter the house facing SW and after I get inside the house I am facing S. Now this is not too bad but you chould enter facing N and then be facing S.


You could rotate every thing in your cell to fix this, but there is a marker that will do it for you - the NorthMarker
I know that in my house cell when I enter I am facing S, so my door is lined up N to S. So, as you can see in the image below, I put a NorthMarker in my cell and set it so that it points NE.


Now when I enter my house the compass matches the outside!
