In the original aoe3, it is possible. Just add some xml code to the ui xml.
But the in definitive edition, the xaml layout controls by the program, and the program will remove it or set “resourcePanel_Asian” Visibility to “Collapsed”(hidden and ignore layout) , even you set “Visible” in xaml.
It should be checking is visible or not, then remove or hide it.
The resource type “fame” and the native center also have the same problem.
By the way, Good news is the a civ can be specific as an asian or a native. In the original game you can’t add those two types of civs.
