This model has problems. The model is displayed far far away and I cannot get close to the main scene (living room and kitchen). I selected everything and I noticed that there are bits and pieces far away from the main scene. After I deleted these I am able to place the camera inside the living room but then I cannot move the camera an see the kitchen the camera jumps to the outside of the model. There seems to be a scaling issue. Is it possible for you to fix this problem? If not then I'll have to request a refund. Thank you.
