Fallout: New Vegas archive invalidation steps.

[Jac]

I've been searching around the Internet looking for the proper way to activate archive invalidation, but had to figure out the best way myself. My findings:

• Extract the attached file into the Data folder.
• Open the Fallout_default.ini file in your FO:NV main folder and find the Archive section.
• Change bInvalidateOlderFiles=0 & bUseArchives=0 to bInvalidateOlderFiles=1 & bUseArchives=1.
• Change the SArchiveList to SArchiveList=Fallout - ArchiveInvalidation.bsa, Fallout - Textures.bsa, Fallout - Textures2.bsa, Fallout - Meshes.bsa, Fallout - Voices.bsa, Fallout - Sound.bsa, Fallout - Misc.bsa.
• Save the file and open both the Fallout.ini & FalloutPrefs.ini files in your %user%\documents\my games\FalloutNV, where %user% is the username you log into Windows with. You may need to clear the read only flag on the Fallout.ini file.

Essentially, the archive invalidation bsa needs to be named Fallout - ArchiveInvalidation.bsa or maybe just ArchiveInvalidation.bsa, and it also needs to come before the texture bsa files. Also, all bsa files FO:NV uses have to be in that archive list, otherwise you'll get pink screens, screwy body textures, and other weirdness. I was having problems with Robert's Type IV body replacer before I did this and now it displays properly.

Are you trying to tell me that FOMM's archive invalidation is faulty?'Cuz it seemed to have worked fine except for what I perceive as "normal" Bethesda bugs, eh?

It didn't work for me, but if it's working for you, I wouldn't worry about it.

Just an FYI: Mod Organizer 2 automates this process so you no longer need the above file if you're using that. If you're using something else, the above steps still work.
