Yes they can, just choose one that makes sense for your map, but I've opted to just use cubemaps for the background, though it is indeed limiting.

The new ones look better :) now if only I knew how to use Photoshop.
If you haven't gotten HSS, it'll help too with lighting especially when using the right skins.

As you can see the floor has awful texture, that's when I would opt for a cubemap, but then you'd need to custom add shadows to show the depth effects.
