http://img694.imageshack.us/g/fallout3201008171738063.jpg/ I'm building a Vault, and I'm at the point where it's time to add some player rooms. These rooms, understandably, have a window to the hallway. However I can't find a doorway corner that will smoothly mesh with the window corner AND The rest of the walls. I end up with the hole in the above screenshot. http://a.imageshack.us/img708/1413/fallout3201008171740442.jpg.

Any suggestions on what prop to use?

May want to go into the GECK forums...I have the same problem a lot, and thats a huge issue with the GECK and Construction Set. Tiles in general really. Maybe size up a rubble pile and cover the gap and give an excuse as to why there's garbage in the hall.

Try VRmWallEndCorInWinL01 and VRmWallEndCorInExSmR01. Those work.

Notice, though, when you put those 2 together, the direction of the pipes on the ceiling. If you want to do long rooms, you will probably have to do them "east-west" in relation to your current rooms (if you imagine your long rooms going north-south)
