Thanks so much for the feedback. I’m already using Datasmith, its an amazing tool.
My thought process is this.
I am finished modeling the interior of the apartments ( There are only 2 styles of apartments, the rest are mirrors or copies of the same style). I only use 2 Apartments for the entire 60 Apartments, but mirrored or positioned differently.
I was think of modeling the corridor which connects all the apartments. That will be one map so the user can look up and down the corridor. When the user opens any Apartment door in the corridor, a new map opens for that apartment. so only the corridor and one Apartment will be open at the same time, so the user can walk into the Apartment, look back out at the corridor. Then when they climb the stairs or take the elevator to 2nd or 3rd floor, a new map opens for that corridor, etc. Therefore I only need a few maps for the entire building, as floor 2 and 3 are copies of First floor. Everything is basically a repeat.
The outside complex, I will have to model the entire shell of the building with no interiors and make the windows 100 reflective.
