Hello, everyone.

views do not fit the new format

And then what???
that decides on its own if changing roughness???

No, I'm sorry. You have to do that.
only the designer can know what scale to use. Moreover, inv cannot know if format changes because in a2 you do not read or why you want to add other views but always in the same scale.
