Place Decor on Slanted Walls?

@chrissyhorn
This is exactly the way I would anticipate your efforts would go at placing decor items on a roofing piece with moo. If items are placed at an angle in the house already (on the roofing) I would guess it was using a method like the mod. If they are not placed on the roof at an angle it's because it's a roof. If there are not items placed at an angle I would assume there was no Mod used to place them. Sorry if that was confusing. Household or wall decor items are not made/designed to place correctly on a roof, not even with moo.

You may want to go through the roof decoration items in build mode and see what you like there that may look nice on this faux wall (roof) area. 

Another thing you may want to keep in mind is that anything you place via moo on the side of that roof piece may stay hanging there when the roof is down/not showing, which can look odd for most items (to just be randomly floating in the air). This happens normally with some items (the air vent for the wall, for example, and some lights) but it's good to test with the walls/roof down to see if you will have any oddly hanging items left there - if that will be bothersome to you during play. That's your choice and discretion call, of course, especially if you're just making it for your own game. I would also expect that if you used the mod you would still have the same 'floating' issues as you would when placing regular decor items with moo when placing them on a roof piece - at an angle or not.
