Quite a few times I've seen permanent light fixtures that don't exist, vents that don't exist, room sizes that are obviously implied to be much larger than reality (e.g. they show a full-size bed, but there's only like 4 feet of space in that location), etc.

I don't particularly mind fake furniture, but if it's very much not to scale I think it's pushing "probably fraud". And when permanent fixtures are fabricated, "blatant fraud, penalize immediately, revoke license on repeats". Using an automated tool does not absolve you of consequences, particularly one nigh-universally well-known to fabricate things.

Oh, and little touches like an ugly fence being replaced by a sweeping view of a beach or a mountain range.
