I was recently experimenting with what can be changed regarding the ui files and thought I would make a couple different HUDs for the campaign screen. These are small mods, and in this case, there are only two color changes, though an infinite number of possibilities exist.
Like any other mod, unpack these and place any single mod in your data folder. Add the appropriate line to your user.script or use ModManager, your choice. Only one mod can be active at a time.
If there is interest, I can make some others (as requested) and/or make some for the battle HUD and some of the other panels so there can be pretty much a complete set.
Attached are the following hud_mini-mods:
BMA_bk_hud_mod.pack
BMA_brit_flag_hud_mod.pack
BMA_fr_flag_hud_mod.pack
BMA_mah_hud_mod.pack
BMA_parch_hud_mod.pack
BMA_wmarble_hud_mod.pack
As a note, use these as you wish, just remember where they originated and give a bit of credit if you can.
