Befor someone sends Devil a "tutorial" on how to add external models
i would like to see if he can figure it on his own.
Its not even hard, it just takes some brain and reading abbilitys.
Look into the original Maps's xml files.

Also, fail.
Items wont show on where you place them.
They always get overwriten by the mansion item locations.

Send me via PM your textures (original, unchanged ones) as a archive/pack.
And i'll chop em down ...
