The next step is to wrap up the corridor system into a digital asset then simplify it into points with attributes. These attributes will reference prefabs inside your Unity project that will be assigned to the level automatically. The key is to organize the points so that the right prefabs are being grabbed and then to make sure the normals are oriented in the right direction. You will also add the floor, ceiling and lights to the level.
