Is there any way to get several roofing patterns to show up on the same lot? Let’s say someone wanted to build an amusement park with differently-styled buildings in the various “themed” areas, or an oceanside club, where the main buildings had tiled roofs, but they wanted thatch over the tiki bar on the beach… I’m guessing it’s either impossible, or somewhat complicated. I know when I’ve tried in the past, all the buildings on the lot take on the same pattern, so I figured I’d ask.

Nope, it's not possible.

As far as I know, no.

I think it's only possible with "flat" roofing/floor tiles (and the floor elevation cheat if you want any kind of shape to it - but don't quote me on that one, as I hardly ever use that cheat), or with deco roofs of some sorts.

I used flat roofs, CFE and some different trims on the roofs of my magic island amusement park https://modthesims.info/d/574466/magic-island.html I also used some awnings and there is a thatched awning.

That’s kind of what I figured. I hadn’t considered deco roofs. The tiki bar is outdoors anyway, so I don’t guess it would matter much whether the roof were actually performing a rooflike function… basically just there to make it look like the guests have a little shade. Okay, thanks!
