The Chicago scenery, including the night/street lighting as depicted in the video below, was originaly deleloped for v7 some six years ago, updated with the release of v8, works in v9 and if Laminar's claims for v10 compatibility with v9 can be relied on, it should work in v10 as well. The video contains a blend of clips of the Chicago scenery from v8 and v9.Granted it is dated, but ALL buildings, without exception, in that scenery were original, created and developed by Xpcities. Because of copyright issues raised by Laminar, none of X-planes original default autogen objects, buildings, etc. were used. Subsequently, the default or resident X-plane objects, buildings, etc. were allowed to be used but without any changes to them and thru referencing only.
Addendum: The copyright issues raised at the time were because the Chicago scenery was offered as payware. Licensing was mentioned as a possible solution; although when licensing was sought, it was in effect, denied. Needless to say, this resulted in significant reworking and delays in offering the payware product.
