HELP with extracting Skybox textures from Palpatine's Office (1.0)

[DamianHow]

Hey guys,

I'm relatively new to the forum, but I've downloaded the "Palpatine's Office (1.0)" mod by RepSharpshooter, over on nexusmods.com.
(which can be found here: http://www.nexusmods.com/battlefront2/mods/374/?tab=3&selected_game=795&navtag=http%3A%2F%2Fwww.nexusmods.com%2Fbattlefront2%2Fajax%2Fmodimages%2F%3Fid%3D374%26user%3D1%26gid%3D795&pUp=1)

And I'm actually looking for some assistance with extracting the skybox textures from the level. I've downloaded the correct tools that I need (or so I believe..), to do so.
I've done some browsing around Google and what not for any tutorials on how to go about doing it, but they aren't very informative and/or clear to follow.

So basically, I'm just looking for some help, from any modders or if anyone knows how to go about extracting textures?

I don't have SW Battlefront 2 installed on my PC and I'm trying to use these textures (for Personal Use only), so that I can add them as a skybox to Palpatine's Office in my "Movie Duels II Remastered" mod for Jedi Academy.

So if there's anyone out there who can help, it'd be much appreciated..
Thanks!
