So I have made a playable Custom Battle Faction!!!
Here is what you need
local_en.pack
-
Text
---faction.loc (Make sure to rename this)
data.pack
-
db
---faction_banners_tables
---faction_uniform_colours_tables
---factions_tables (For the unique ID I just took one of the last ones and added +1, not the safest but it works)
---units_custom_battle_permissions_tables
-
ui
---flags (under this you can create your own folder, I named mine Sparta, and copy one othe the other factions flag contents and then just modify those for your needs. For the .dds files uder the Flags folder save them as (DXT3 ARGB 8 bpp | explicit alpha)
Hope this helps
