I was able to model the cup and the hole and place them in unity model. As far as I understand I need to apply a collider to the hole model and I think it should be a mesh collider. However, when I apply it, it does not exactly matches the model for some reason(see screenshot). How can I fix it? I am attaching the package as well. e.nagovitsyna.
