Here is the same model exported as fbx and obj. FBX is 844kb, OBJ is 22.4kb. For a static prop like this there is no benefit so I would usually use an obj.
But once we build the unity project, do the models remain in that format, taking up the same amount space? If I was only using fbx's for everything, woudl I be wasting space?
