Sci-Fi Modular Rooms Is a collection of easy-to-fix rooms and corridors.
All rooms snap together saving time on aligning objects
It also has a step-by-step builder that only gives options to add rooms you can connect
When the rooms are in place, it's just one click to add all the doors to connect them.
And the doors will hide the rooms behind them when closed, saving render time.
