The design of the map is unreasonable

It is reasonable to adjust the size of the object and the scaling map changes with the object, but I first adjust the size of the object and then put the map in. When the size of the map changes, it is very unreasonable, so I need to adjust the size of the map twice. Of course, I can export obj first and then import it, so that the size attribute of the object will become 1:1:1, But it's too troublesome. I don't think the map size changes with the adjusted object size.
