hey, thanks, sorry for the troubles. There's a bit of a learning curve, and sometime a person space can just give major problems.
I can help you get an .fbx model. basically, we schedule a time to meet in multiplayer , and I load into your space within unity (my game engine) I can drag and drop your home layout into a prefab and basically email you an .fbx file.
