Buzzit-
Here's a picture of my scene, I have made the building and with that the foundation part, the piece that will show up when you have a lot in a hilly area. When it's time to do an export to the game, you want to make a custom LOD's if not the lot will not look right in the game.


when it come to making LOD's you have to be careful and try to make sure that all the items on the building are in the custom LOD's. When I made my slope frindely bats the foundation is not connected to the main building, why is this is because the foundation LOD's need to be tight as possable, all I did is make a second copy of the buildings foundation and selecet one object from the copied foundation and right click and press editable poly and attach all the items on the second foundation. When you finish your LOD's you must clone it three times name one LOD3, the next LOD4 and the last one LOD5 remember the Lods has to be right on the building model.



When it comes to making slope friendly buildings you will have to do some moding, so you will need the Iives Reader to do the moding if you don't know. were you see building foundation you want to enter in 0x194B100, if you do not see building foundation in the reader then you will have to right click and go to add property and find and add the building foundation, what this do is it get rid of the maxis foundation this will show up on you lot when it's on a hill. So the only foundation that should show up is yours. In the lot editor the things I have play with is the threhold and the elevation change, in max elevetion on my lot is 6.00 so it should not grow on a very steep hill. Anything above 4.00 like 8.00 that means it can take on a steeper hill.


I hope this help you out, I tried my best.
