So how do you get 3D floors, backgrounds, skies, etc. in there?
import them from other stages, or use 404s stage builder stuff.
Heres what I got so far from using his stuff and an import from the yoshis island stage:
You just gotta get creative with the items provided. You can put them over each other and stuff to make more complex shapes. But if your trying to make really complicated things then idk... alot of other stuff is imported from other games, trophies taken from the game and resized, stuff like that.
Take a look at Kariko village:
Most of the buildings are simple squares with triangles on top of them. I bet it would be somewhat easy to remake with stage builder items and an import of the windmill from pokemon stadium.
And thanks for the info mewtwo!
