In this case, I'm trying to create some objects that I can put into my house. At the beginning, I used MAYA to create model, such as toaster, lamps, art frames, etc. And then, I put these things into my Unity package, adjusted the position of them, also I had some troubles with the scale of things, it is not really fit into my house, even it was correct size in MAYA, I still need to adjust the scale. After that, I used substance designer made material for my toaster. At the end, I back to Unity, tried to map lighting and repaint the walls, also built the collider.
