I'm making a mod which will feature a 'pocket plane' created by a mage, it will be fairly small, perhaps the size of whiterun. I dont need terrain.
I want there to be a sky and weather etc, but the tutorials regarding this for Exteriors are lacking.
There is a great beth tutorial for interiors however, is it possible to use an interior for this?
Are there any issues I need to be aware of? For example I will need to see into the void, but I need the void to have a sky.

I also need to think about if the player falls into the void, can I create a trigger to kill the player if they fall?

Just looking for some advice, I'm a real novice in the CK and have been fighting it for days trying to get what I want from an exterior, but I think an interior may be a better bet.

Yeah, I need a sky in my mod too, would be great to get an answer.

http://www.creationkit.com/Cell_Lighting will explain the sky and weather in an interior cells.

Edit:http://www.creationkit.com/Interior_Cells a better consolidated source for cell tabs.
