Is it possible to make one level with different styles - for example one part of the level in garden-style, another in spooky-style and a third part in sand-style?
I'm affraid not You can make it seem so by using CustomModels, but it's not quite the same. I did this in my Tut's Treasure VII level. Take a look at it in the editor and the models, then you can see how it can be done. Maybe you'll come up with something fantastic
