Hello,
I have fallen in love with the Creation Kit, but I have run into something that I cannot find a clear answer on.

What I am trying to do is to create an underground city with multiple areas that the player can enter such as houses, caves, trap doors, etc.

What I am confused about is how/if I should make say the interior of a house a seperate interior cell from the main interior cell, then link the two by a portal. Or if I create the interior of the house in the same cell and link it that way.

I have seen the video of linking a interior cell to the world, but nothing about interior to interior.

Sorry for the newish question.

Cheers.

Well depending on the size you might want to make that main area a world space. Think of Blackreach, that big underground cavern/city you go to in the main quest. You can take a look at that area to get an idea of how it was set up. As for linking things, doors can be used for everything you described. I haven't watched that tutorial video yet but it should be the same process for interior to exterior and interior to interior. You can even link doors in the same interior cell.

Just create a new interior cell for each house (the same way you created the original main interior)
Put doors of your choice (found in the "Doors" category) in the main interior AND in the house interior. Open up the reference menu for either of them, navigate to the "Teleport" subsection and locate the cell you wish it to teleport you to, and the find the correct door in the drop down menu.

Thank you both, I will give that a try when I get home.
