->>>>>!!!!!!http://sites.google.com/site/oblivionpoinfo/ and very much "In Progress..." Please start contributing by posting crashes/problems, solutions or pictures where applicable (in this thread.) Generally, these should not be mod-specific troubles. I would detail what "mod-specific" means, but the idea is not solid in my head right now. I will post examples of "issues you will not see" as they come up, for now. I am also looking for OBMM scripts for any mods around. I will post a few of my own soon, before just going ahead a trying to rewrite the 300 or so I used to have.

I was working on a guide by Blade of Mercy in order to try to smooth the last one-to-a-couple-hours crash from my game. When I came across steps involving, PyFFI, a Python program, and checked it out and found myself hesitant to proceed. Using PyFFI to optimize meshes definitely helps improve FPS, so explored for more answers. I asked in the New PYFFI Automation Tool thread, and the author, Dan (Kandiedan), warned against inexperienced users doing this themselves because you need to know how to check for bad meshes. Well, soon after, other experienced modders assuaged a number of my concerns. Now I want to spread my confidence and, recently, amassed information about PyFFI and other ways to optimize and stabilize Oblivion. Dan's advice is still important, if you see mesh issues in-game, grab your backed-up original meshes, and try PyFFI-ing again. For the time being, here are a few PYFFI-related and performance-related downloads available:

http://sites.google.com/site/oblivionpoinfo/optimization/pyffi
Latest Version: 2.0.2
http://www.tesnexus.com/downloads/file.php?id=25423 by kandiedan (Dan)
>>> Comes with an INI file that is supposed to be able to skip certain file types.

Make sure to download the latest version. (There is a link in the header above to the PyFFI site.) After installing
the latest version, when you right-click on a folder "Optimize with PyFFI" is now an option. Warning!!! The
regular PyFFI tool modifies the original files, so make sure to have a back up of whatever you try to optimize
somewhere. A number modders have recommended avoiding the creature and character folder, and also files with
EGM files (i.e., certain helmets and head meshes.) Bad meshes, generated by PyFFI or by hand, can cause
problems, that is why it is important to check meshes after running PyFFI. It is not impossible, but the process
(when done thoroughly) may be very time-consuming.
Note: http://www.gamesas.com/bgsforums/index.php?showtopic=1014947 will output optimized meshes
to a separate folder (of your choice) and does not modify the originals.

Recommended Folders (and Files) to Avoid:
1. Characters
>>> PyFFI can have trouble with Transparencies ~Arthmoor
2. Creatures
3. Effects
4. Files with EGMs (i.e., helmets and head meshes)
5. FX (i.e., "meshes\dungeons\misc\fx")
6. Landscape - Waterfalls
>>> PyFFI can have trouble with Transparencies ~Arthmoor
7. Triggers
8. Arthmoor's other specific avoids:
>>> Landscape waterfall meshes, Texians Animated River meshes
---->>> PyFFI sometimes butchers the transparency information
>>> Hair meshes

Iffy? PyFFI Avoids:
1. Armors
>>> Note: You may also want to avoid armors, especially when using replacers.
>>> WATCH OUT! for EGMs
2. Weapons

Your attention please!!

Oblivion:
Download the latest http://www.elderscrolls.com/downloads/updates_patches.htm.
>> Note: The Game of The Year Edition (GOTY) is already patched.
>> Make sure to get the correct patch!!

It is usually better to leave your Oblivion INI to its default settings, unless you are changing video related settings. (This is epecially true of the v1.2.0416 update INI file.) Other safe edits are changing your main menu videos, border regions, screenshot and other INI settings that are required for visual enhancement or reduction. Many of the available tweak guides are out-of-date, so if you are thinking about "tweaking" your INI, find current information about it before doing so. Also, if you find that you are missing certain lines or settings, you can add them if you know they exist. (Ask if you are unsure about a settings existence and/or placement, which group it belongs to.) Also, remember to try regenerating your Oblivion INI files when troubleshooting CTD on load and related issues. Regerating the INI is as simple as moving the current one out of your "My Games\Oblivion" folder (to make sure you have a back up) and clicking on the launcher. Oblivion will not overwrite an existing INI.

Some "Regular" Oblivion INI Edits:

This is another case where it is safer for modders and more experienced users to do the job themselves. However,
TES4Edit's function, "Undelete and Disable References" is pretty safe, and it helps alleviate a problem that is a known
source of crashes. That is a function for everyone. Warning!!! Not all "Identical to Master" records should be removed!

Thanks for the thread,
Question though, is it safe to pyffi the Vanilla meshes with the Pyffi Automation tool?
Cause I can't get the Pyffi-ed Meshes Patches to work

It works. I just did it yesterday. Did you download the latest version of PyFFI?

Edit: What problem did you have, specifically?

Yep, I got the latest version
One thing I'm concern about is this from the PyFFI-ed Mesh Patches:

"There have been reports that this does not work with GoTY edition Oblivion. If you have GoTY edition it may not work."

EDIT: I can't find the Optimized Folder

Here is what I did:

1. Download the compressed file to a separate folder

2. Use 7-zip's "Extract Here" function

3. Use OBMM to extract the meshes folder files into that separate folder

4. Put the newly extracted meshes folder into the "Separate Folder\PyFFI-ed Vanilla Meshes Patch\Original" folder

5. Click ApplyPatches.bat

6. Compress the "Meshes" folder in the "Separate Folder\PyFFI-ed Vanilla Meshes Patch\Optimized" folder generated by the patch


Do those steps not work for you? I wonder what the difference is with the GOTY version...

Thanks, I'll see what I can do

For whatever it's worth, anything I release that has a mesh has been optimized. I guess if people consider this useful information I'll go list it in my readmes

I'll add it here too.


Thank you as always Arthmoor!
- Tomlong75210

I just apply the patch and found the Optimized Folder, but there's no nif files inside. Only folders

Here's the error:

"The system cannot find the path specified"

Is that error generated after running the BAT file? Do you know if it is generated by PyFFI not being able to find Python or something? Here is a PIC of what I had, after using OBMM to extract the meshes to the "Original" folder and clicking on the BAT file: http://s244.photobucket.com/albums/gg24/Tomlong54210/?action=view¤t=PyFFIpatches.png.

Edit: Is that message being generated after each patch attempt? (I tried to recreate the error.)

The error appear after every nif it patch
I think I'll reinstall Pyffi again because right now, its currently installed in the Program Files

That is where mine is.


Edit: That error should indicate that it cannot find your NIF files. I am compressing the meshes folder that I extracted from the Vanilla BSA, and I will upload a picture of the paths for you to compare with yours.

Thanks Tom,
but I guess I'm not the only who have this problem
I took a look over at the Tesnexus Pyffi-ed Mes Patches comments, and saw that many user has the same kind of error I got

I really wish I knew what was different about the GOTY version. Did any of the comments suggest solutions?

Edit: It looks like it tries to patch the Anvil architecture first, so here they are...

Nope, I looked through all of them and still no solution
I guess I'm going to use the Pyffi automation tool for the Vanilla Meshes then

If the patches are binary patches (which I'd assume they are) and there's even 1 byte's worth of difference in the GOTY BSA archives, then the patch process should logically fail. Using the patches isn't really necessary these days. Just unpack the BSA and use the most recent PyFFI. Right click on each folder you want done, and go for it. Takes a lot less time than it used to when you don't have to sit through thousands of files by hand. Still best to avoid hitting the creatures/characters folder of course and you need to be mindful of not hitting helmets that have .egm files.

So that's what caused it

I am going to note that underneath the link to the patches. I will also add more notes on using PyFFI in general as well.

@Arthmoor: I want to optimizes the QTP3 Blood&Mud meshes. How do I go about checking meshes afterward?

Since my Oblivion is GOTY version, I decided to normally PYFFIying my Oblivion - Meshes.bsa. This is what I do:

1. Copy-pasting Oblivion - Meshes.bsa to separate folder.

2. Unpacking using OBMM.

3. Selecting PYFFI-able folders and PYFFI them all.

Now here's the confusing part:

I finished PYFFIying them all but I don't know what to do. Do I have to copy-paste pyffied meshes to oblivion\data\meshes? or do I have to omod it? or do i have to repackaging it together with other unpyffi-able folders and overwrote original Oblivion - Meshes.bsa?

Thanks in advance.

Do not PyFFI all folders. Under the "Using PyFFI" section I tried to emphasize some warnings against using PyFFI on clothes, fx, files with EGMs (i.e., some helmets and head meshes), and the character and creature folders in general. You may want to skip armor as well. I will try to add more emphasis to that part. This does not mean that you have to re-do the job, just delete the "clothes," "characters" and other folders containing the types of files I just mentioned before you package the newly-optimized "meshes" folder. (It should be backed up, and probably compressed for BAIN or OBMM installation.) I would not just drag it into your data folder because you may overwrite changed meshes (for say a body-replacer or something.)

Edit: These files are not "special." Treat them like you are installing any other mod.

This the folders I had PYFFIed beforehand:

1. architectures
2. clutters
3.. dungeons
4. furniture
5. landscape.
6. plants
7. rocks
8. sky

does this correct

well maybe I will unpack my Oblivion - Meshes.bsa again to yet another separate folder. and copy paste pyffied folders to that folder, overwrite all, and repack again to bsa. Is this correct?

No need, that list looks fine. I did not know there was a sky mesh folder, haha. Pack those up with OBMM or for BAIN, or simply for safe-keeping. Then, install the package using the respective utility.

If I do this, does that mean now theres, say, 2 architecture folder on data\meshes\architecture directory(one from my omod/bain and one from original Oblivion - Meshes.bsa)? I wonder if the system won't confuse this or is that what "Reset BSA timestamp" utility for?

Use the reset utility to make sure (uncompressed) data files are loaded instead of their BSA-counterparts. The system loads the newer files. You should just use that reset function every time you install a BSA, and you will not ever have to worry about Oblivion using the older resources.

Ok, all done and just played vanilla and SI with increased 3-5 fps.....great. Now time to pyffiying SI meshes. Thanks for the information!
