Export and set up in Unity

This step is pretty straightforward. Once you made sure everything is in order - export your models into Unity. 

Because my room is static and almost every object remains at its original spot, I exported my scene as a group. If your scene has very high polycount I do recommend exporting piece by piece. The same counts for models with deformations.

Once in Unity you can begin setting up your project.

It’s best to set up your environments in separate scenes, unless they are directly connected to one another. Personally I find having separate scenes better - it helps to avoid confusion with effects and lights and gives you much more flexibility.
