Hello, I am making motorbike game, I instatiate a motorbike in a garage: in editor it works fine (every time I change a vehicle a instantiate a new one). On my old laptom it worked, but a week ago I had to switch laptops and it had broken meshes in export (just switch only). The rest of the game is fine. I am using Unity collab. I have tried to change shaders, refresh and reimport folder with models. I think that the problem is that the reference in mesh filter unasigns the mesh.
