I have begun retexturing the shipped maps that came with SWBF2. They are replacers and only swap out .tga files, edit .fx and .lgt files. As I understand it, these can be edited and remain multiplayer compatible. If someone could check this for me that would be wonderful. Take a look and see if it's your kind of thing:

BF2 has always been a favourite of mine, i've come back to it many times over the years on both PS2 and PC and have enjoyed every revisit. I've been playing a lot of other peoples mods and thought i'd contribute.
I've been lurking on these forums a fair bit recentlym, they have been really helpful
Cheers
