Getting ready to setup a modded Fo3 game (GOTY - 1.7). I'd assumed (I know, I know) Fo3 would be essentially the same as Oblivion. When I went to check if fomm had correctly set up archive invalidation, I noticed the falloutprefs file. I cruised through both and noticed there was no archivinvalidation in fallout prefs, but there was in fallout.ini, will this matter?

This should probably be moved to "Hardware/Software Issues" Subforum.

But I think it matters, may not. All it does is change the "0" to "1" so why not just go to Fallout.ini and search "Archiveinvalidation" or whatever and just manually change it. if it doesn't work just reinstall archiveinvalidation and try it again.

I think this is the appropriate forum because the question at its heart, is whether fomm in a GOTY v1.7 game, is sufficiently modifying the .ini's to allow a modded game to run.

Ah. Well then. My advice still stands.

If all else fails, you are going to want to grab http://sourceforge.net/projects/fomm/files/ to place your mods into proper ordering. Fallout mod manager has the "Toggle invalidation" button to the right side to make things very easy You just click it once and forget about ever having to worry about textures not showing up correctly in your game again.

Thanks 50pieceSteve, I'd forgotten to read through KG's guide (even after making a personal .pdf for myself, LOL!). I appreciate the thought Miss Sparkle but, fomm = Fallout Mod Manager. The whole point of my post was whether fomm was working sufficiently. So, if you are using fomm, would you check both the .ini's in your game to see if they both have archive invalidation? TIA. If not, and your not having troubles gaming with mods, then the lack of archive invalidation in both .inis isn't an issue, just a curiosity.

Falloutprefs is bypassed if you are using FOMM and/or FOSE, so there's no point to it. FOMM does archive invalidation perfectly fine.

Thank you Kai Hohiro, for those excellent bits of information.
