Problem with getting some of the ceiling tiles to match up.

I followed the level design tutorial, and it says that the middle tiles are important, and that they need to be arranged in a specific way to avoid this.
But I did that, and only managed to rectify some of the problem areas.

I have a NorHallSm1wayStairs128ExSm01 stairway, coming down, and joining a NorRmSmWallFrontExSm01 door.

This is one of the areas where the problem exists.

The other is around the

NorHallBg1wayToSmFront01 (a big doorway leading to hall)
which is connected to NorHallBg2way01 (a 2 way hall sized tile - its like like an L shape)

On eitherside of the door, I have NorRmSmWallSide01
and it is pretty much between these two pieces, and the door in the middle that I get gaps that allow me to see into space.

Make sure that you're using pieces with "front" on parallel sides of the room, and pieces with "side" in the name on perpendicular walls. With that set up correctly, then you should be able to rotate the Mid piece ninety degrees to resolve the ceiling gaps.

If you're still having trouble, http://www.creationkit.com/images/f/f2/LDLayoutPart1TutorialComplete.esp from the infobox at the top of the tutorial page.

Hi Joel,
Your my hero, if you were local, I would Marry you or do favors for you - whichever is amicable to both of us, we might want to take things slow though, because Whirlwind Relationships very rarely work out, especially when long distance.

The problem was that I was using a Front Door, where it was meant to be a Side Door.

This is a quick walkthrough of what I have built.
First time making any sort of map for an Elder Scrolls Game.

Planning on putting my Amulet (which is on Steam Workshop) at the end of the Dungeon.

Interestingly enough, the Visual Effect for the Ward, does block spells, but doesnt block people...
