Different Styles in the default UI and how to aktivate?

[DuKe2112]

I have started playing around with the interface recently and noticed that there are two different framesets in the default UI image folder.

First the standart and pretty dull borders, as you can find in window_elements_generic.dds or window_elements_specific.dds.

And second some finely detailed decor, as found in window01.dds or def_widgets.dds that I have never seen in game.
But I have seen screenshots of people using it.

can someone explain to me why there are two, and how to switch them?

You cannot easily change to older UI appearances. The current blue default UI style appeared around the end of 2005 and Desert of Flames. Most UI image files older than that are just legacy files that are not used any more.

Ah, thanks for the info. I suspected, that one was an old version, but due to the detail level I believed the order to be the other way round.
So that the default one was the old and the other was a new one to be activated if one wishes to do so.
