Replacing meshes in bsa files (pyffi-ing)

[chgharland]

Hi all

 

Just want to be sure I am doing this right.

 

I am PyFFi-ing meshes from the oblivion bsa file by unpacking the bsa to a new folder on my desktop then doing the PyFFi to the unpacked mesh

folders Architecture and Clutter.

All that is not an issue – looks like all is working successfully.

 

But, what is the best way to replace the meshes in the game with these PyFFied meshes?

 

I have been creating an OMOD with no esm or esp (just the meshes) in OBMM and activating it with Meshes ticked in Archive Invalidation. Is this the correct way of doing it or should the PyFFied meshes be repacked into a copy of the orginal bsa file and that bsa used instead of the original one?

It’s difficult to tell if the game is using the PyFFied meshes or not.

 

Cheers

In my opinion, the easiest thing to do would be just to repack the meshes back into a BSA file with the same name. For example, if you're doing Oblivion - Meshes.bsa, just pack the PyFFI'd meshes back into a file with that same name, and overwrite the original in your Data folder.

The only additional step that's needed is to change the creation/modified date on your new BSA - you want to give it a fairly old date such as 12/6/2006; if you do so then Oblivion will still correctly load other meshes such as Unofficial Patch meshes or modded content (provided those have a later date than the BSA you just created).

 

Edit: Also be sure to set the correct flags on the new BSA file. If you don't then Oblivion won't know what resource types are in that BSA, and they won't load.

Ok thanks, how do I change the creation/modified date and how do I set the flags, knowing that I have set them correctly?

What are you using to unpack/repack the BSA file? If you're using BSA Commander then it's easy, you just click on the two "flag" buttons at the time of packing (archive flags and...I forget the other one), then hit OK. BSA Commander will figure out what flags to assign, you don't need to hit anything else.

 

As far as changing the date, there's many programs available online that can do that easily. I'd recommend just trying Google.

Yep I'm using BSA Commander

 

OK, I guess I'll google "windows file date change" ???

 

Edit - got one that works :)

PyFFI - http://tesivpositive.animolious.com/?page=pyffi <-- There are a couple things to be aware of as you repack the BSA.
