Thanks for the advice man it helped me a bunch I ended up working it out thanks to you!
Just for anyone else who may want to use this mod and encounterd the same problems as me what I did was using kotor tool I opened both the heads.2da and portraits.2da from the mod and opened up the same files from my override folder and copied the changes from the mod .2da files to my .2da files and saved.
A few years back I had a list of about 5-6 large Battlefront 2 mods as a mod compilation installed in a specific order for maximum compatibility but unfortunately I uninstalled my BF2 from Steam and deleted the data a few months ago. I'm looking to play the game again with a mod compilation installed. Unfortunately I can't find a mod list with full compatibility so I was wondering whether anybody has a mod list they can send my way as I don't want to randomly install mods and regret it later haha.
Any help will be appreciated.
Many thanks all
