games do not re-compress files when they are run so the compression code was not in the exe.
this is a one way only process of extracting files from the archives like the game does.
your best bet is to try to get the game to load uncompressed files outside of the .par archives.

gildor has an unreal package decompressor.
unreal will read the uncompressed files it outputs and you can modify them to your hearts content.
this is how people are modding mortal kombat.

having a few compressed files would help in testing.
you need the compscan2.bms and compscan2.bat file to test for compression.

Dyn_Playercostume_Species_Drow_F_01.Wtex is a plain dds file after you delete the first 0x24 bytes

I just extracted the file you posted with the script you are doing something wrong.
open a command prompt and do this

c:\quickbms.exe c:\qb.bms c:\file.dat c:\extracted

and the files will be extracted you might want to re create the bms file I have a feeling you are using the wrong one.

extracts fine for me.

I have updated the Script it reads directories now. There will be about 5 or 6 files in the entire game that will complain in quickbms due to Korean characters just rename them and your all set.

I don't have the game so feel free.

yeah i wanted to do the same thing never got around to it.

the textures are embedded in the nif files so names don't do much anyway. and the nif format is to new to be supported so archive extraction wont do any more then offzip does.
