Hey, Nol--I'm sorry if this questions sounds terribly naive.
A lot of the older wall sets come with information, like, "Use in Forest A" or "Caves" or "Marble."
I've not been able to use some of the wall art that others have uploaded. There was an awesome set including a fountain, I believe by Landry, but I could never find a way to import it that did not look...well, it never looked like a fountain in the game because I could never find the right wall slots...
I've gotten the impression that I might just be using an outdated program (WallEdit), but I haven't been able to get any farther with Dan's Toolbox program, either.
All that to say, Is there a specific wall set these are made to replace?
(Or, alternatively, I am just doing it wrong?)
