When I import my model from maya, the textures appear on the outside of the room.
How do I go about fixing this?
Some more details would be greatly appreciated to help fixing your problem 
First of all, if a texture is not showing up, did you check the normals, cleaned the whole mesh up? Did you maybe use a wrong shader for the room, like skybox or sth, this happened to me one time, just a missclick and I was wondering why it is not showing up 
I think I cleaned up my models before importing them. I combined most of the meshes, and deleted all the history. I know that they are using the right shaders, I’ve double checked and there are textures but they are on the outside of the room.
My UVs seem to be right, and in maya it looks right. I’m fairly new to this all so it’s probably something silly.
Thanks for your help,

My guess is your Normals are inverted, just flip em and it should be fine.
