Ramifications of BSA Extraction in Mod Organizer


z929669

Question

This will graduate to wiki guide format once we get sufficient community input ...



 
I am creating this thread to address some important information about BSA extraction and related modding concepts that come up over an over again with respect to STEP's use of Mod Organizer (MO) and MO/STEP critics that disagree with STEP's general advocacy of BSA extraction and MO's BSA-extraction functionality. In order for this to be meaningful to all users, I am providing some background information required for understanding the ramifications of BSA extraction and why STEP advocates it while other respected modders do not.
 
WARNING: Extracting BSAs deviates from the intent and expectation of the respective mod provider, so it is fair to expect that once a user extracts a BSA supplied with a given mod, that mod's author has every right to refuse support on the basis that the user implementation is no longer the same mod. Further, if a user extracts vanilla Skyrim BSAs, ALL mod authors and the modding community at large have the right to refuse ANY support to said user!
 
NOTE: The STEP community follows Wrye's cathedral model of modding, and since we advocate experimentation and an open modding approach, we also try to encourage 'creativity' (but not flagrant stupidity, TYVM) and users are welcome to support each other in this community, and we'll do our best to help as we are able, particularly with regard to what we advise in any of our guides. After all, modding is a largely creative endeavor and a learning experience!


 
Executive Summary
 
STEP provides instruction for a range of methods to mod Skyrim. Novice users can follow the STEP Guide, which is pretty straight forward and adheres to conventional modding methods. More advanced users or users that want to take it further can follow the additional guides and employ some more advanced and less conventional techniques (like BSA extraction and texture optimization) that we have found to be viable and optimal for the 'perfectionistic' or 'adventurous' modder. Some of these techniques are traditionally the jobs of the mod providers rather than the mod users, but we encourage and empower our community to take on these tasks if they wish, because many mod providers do not optimize their mods, and we advocate customization of mods by the user.
 
STEP advocates BSA extraction because it allows for more granular control of the modded Skyrim (but see 'cons' below). Critics object that this practice 'breaks' the fundamental standards of install-order and load-order methodology that many mods and modding utilities are built around. Nevertheless, I and many STEP staff and members have not found this to be the case and propose that these concerns likely stem as a result of Mod Organizer users having problems and complaining and blaming the mod authors on mod threads like the USkP when something goes wrong with their game. Why MO users? Because MO is the only mod manager that exposes BSA extraction to any user that installs a mod with a BSA in it (basically, all MO users).
  • STEP advocates BSA extraction (given the user understands the ramifications!)
    • It is a prerequisite to texture optimization (NOTE: repackaging vanilla BSAs is possible with CK's Archive.exe but problematic with BSAopt)
    • Used properly, it does not cause any load-order issues at all
    • It allows more granular control of a modded setup
    • It can theoretically lead to excess disk fragmentation (HDDs only, not SSDs)
    • It can theoretically reduce in-game performance if most/all game assets are loose files under a heavily-modded game
  • BSA extraction is not 'bad' (NOTE: it can alter the intended behavior of a mod's interaction with other mods if used improperly)
  • BSAs are not 'bad'
    • simplify mod distribution
    • simplify user maintenance (NOTE: particularly for manual installation and traditional mod management ... but NOT for Mod Organizer users!)
    • simplify support by mod providers
    • BSAs are the future trend in Bethesda modding, so best to get used to them



 
Install Order vs Load Order
 
A word about game assets: Game assets are any files (resources) that get used by Skyrim. Plugins (*.esm & *.esp) are special assets that are used by Skyrim to call upon other assets and to provide instructions for their use. Thus, plugins are the 'brain' of the game. The only plugins needed to play Skyrim are Skyrim.esmUpdate.esm. Other plugins are from the DLC add-ons or other mods made by the modding community like the USkPs, etc.
 
Install order: The order of mod files installed onto disk. If two mod packages contain the same file names along the same file paths (e.g., textures/blah.dds), then the last installed version overwrites (i.e., overrides) any previous version and is thus the version that will be used by the game if it is called upon by the game (via a plugin). These mod files can be anything at all (e.g., text, images, ... whatever), but only certain file types are used by the game: textures, meshes, scripts, plugins, etc. Therefore, install order affects what resources the game will use.
 
(NOTE: MO does not install mods to the data directory, but rather mods are extracted into mod folders within a user-specified location. MO creates a virtual /Data/ that appears to Skyrim as the actual /Data/, and it populates this virtual directory with mod assets from the install directory as specified by the MO installation priority. Otherwise, there is effectively no difference between MO and other mod managers, but this difference is fundamental and confers a significant advantage to MO users).
 
Load Order: The order that plugins are loaded into the game. Like install order, the last plugin loaded overrides all previous plugins. Since plugins reference assets within /Data/ by file name, there is potential for two different plugins to reference the same named resource.  Additionally, since plugins provide instructions as to the use of these resources, load order can also affect game behavior. Therefore, load order affects both what the game will use and how the game will use it.
 
What are BSAs?
 
Mandatory reading: read this important background information!
 
BSA: A proprietary archive of game assets that mirrors /Data/ directory structure. Thus, a BSA file is an archive exactly like a folder that is simply packaged as a file. The same is true of any ZIP or 7z archive.
 
How do BSAs Work?
 
For Skyrim to be 'aware' of a BSA, it must either be registered in Skyrim.ini or loaded with a plugin of same name. Once recognized, the game sees any BSA as part of /Data/ itself; however, when conflicts exist between files contained within a registered BSA, a plugin-loaded BSA or within /Data/ as loose files, things are a little trickier:
  • Registered BSAs: These load at Skyrim start in the order that they are listed in Skyrim.ini, last loaded BSA 'wins' in event of resource conflicts of contents within.
  • Plugin-loaded BSAs: These load when a new or saved game is loaded after Skyrim starts. Each BSA is loaded at the time the plugin of same name is loaded. So any BSA with content resource conflicts corresponding to a plugin will 'win' if its plugin is loaded after the conflicting plugin. Basically, these BSAs (and all of their asset content) are referenced by their plugin and loaded according to plugin load order. Plugin-loaded BSAs always 'win' where they conflict with Registered BSAs. The only exception is with respect to resources required at Skyrim start but before savegame (or new game) load, like No Menu and Loading Smoke.
  • Note about loose files: Loose files always override same files inside of registered AND plugin-loaded BSAs!

 
Summarizing in terms of prioritization and load order ...
 
Skyrim asset priority:

  1. Loose assets always win
  2. Plugin-loaded BSAs win all but #1 (EXCEPTION: plugins are only loaded when a new or saved game is started, so plugin-loaded BSAs have zero priority with regard to pre-game assets)
  3. Registered-BSA assets lose to all #1 & #2
  4. Registered Skyrim BSAs and other official content and DLCs behave no differently than "after market", mod BSAs

Plugin/BSA load order:

  1. Registered BSAs load according to list order in Skyrim.ini
  2. Plugin-loaded BSAa load with respect to the corresponding plugin load order
  3. Plugins load according to %USERPROFILE%/Appdata/Local/Skyrim/plugins.txt, which is managed by BOSS/LOOT

BSA Pros:

  • Keep the Data directory clean and uncluttered (NOTE: this does not apply to MO users though, since MO uses the virtual file system).
  • Allow easy mod management, since all of a mod's files are much simpler to identify and update or remove (mitigates user error= less support burden)
  • Make it easier for mod authors to distribute and maintain control over how the mod functions (mitigates user error = less support burden)
  • UPDATE:
  • Better performance (NOTE: a lot of loose files slows down game startup, especially when using MO)
  • Less disk usage (NOTE: BSAs can be compressed; HDD fragmentation is less of an issue)

BSA Cons:

  • Removes an element of user-level control ... and many mod users are control freaks (STEP especially)
  • Users can no longer efficiently see contents of a mod (NOTE: although Wrye Bash does expose this information, albeit with a performance hit ... is this functionality inherent or is it off by default??)
  • Incentivizes mod authors to provide BSA 'hotfixes' as loose files (NOTE: This has undesireable ramifications for MO users due to behavior of BSA extraction in MO ... BSA extracts last, so loose file hotfix is overridden by original version within the BSA! EDIT: this is fixed in the current beta and next release of MO)
  • Mod authors are forced to upload all files (the entire BSA) for any updates (all files are contained within a BSA), and users are forced to either download again or deal with the issue just previous if the mod author has supplied a 'hotfix'-type update.

BSAs & Steam Workshop
Steam Workshop only allows mods that use the BSA + ESP format. STEP finds this overly restrictive and unnecessarily 'controlling'. I personally resent it and only deal with Steam because it is the wrapper for Skyrim (unfortunately, IMO). The Steam Workshop and Steam-Skyrim community are valid entities that do not deserve to be totally ignored, but STEP does not recommend that it be used as a primary source for mods or modding information. The Nexus is the STEP-preferred source for all modding needs. For information, STEP is a good primary source, and we point to the best alternative sources, but here are a few others:

BSAs & Mod Organizer
 
Since Mod Organizer allows users to extract BSAs during mod installation, MO potentially obviates any functionality of registered or plugin-loaded BSAs. Thus, any mod that uses a BSA is effectively constrained henceforth by rules pertaining to loose files, so its assets are no longer linked to hierarchies of BSA registration order or plugin load order. This and the fact that all or user-specified mod resources can be loose and manageable by MO confers a clear advantage to the user.
 
BSA Extraction Pros:

  • MO users have a much more granular level of asset control and can prioritize BSA contents at the loose-files level
  • It is a prerequisite to texture optimization (NOTE: repackaging vanilla BSAs is possible with CK's Archive.exe but problematic with BSAopt)

Other issues can arise though, so only informed users that understand the ramifications should be using this functionality (unpacking BSAs). Following are some things to be aware of when unpacking BSAs (that mod authors intended to remain packed as delivered!).
 
UPDATE: There does not seem to be any need for standard users to extract mod BSAs in MO, because once can subvert the constraints of the standard load order/asset prioritization system from the Archives Tab:

  • Plugin checked, BSA checked - Follows mod priority order for conflict resolution. Plugin does not affect the situation at all.
  • Plugin checked, BSA unchecked - Follows plugin load order for all unchecked BSAs. All loose file assets will "overwrite." OTHER checked BSAs will NOT overwrite, which is why unchecking BSAs can lead to unpredictable results or dificult-to-resolve conflicts (hence the :!: warning).
  • Plugin unchecked, BSA checked - Follows mod priority order for conflict resolution. Plugin does not affect the situation at all.
  • Plugin unchecked, BSA unchecked - As if the plugin and BSA don't even exist in the mod setup.
  • Furthermore, MO will scan all mod BSAs (aside from those in /Data/) and include these assets in the Mod > Information > Conflicts tab. So in MO, BSAs effectively behave like loose files when checked in the Archives Tab! Mod developers will still find the BSA extraction functionality handy for testing purposes during production of updates to their existing BSA-packed mods or when developing new ones dependent on assets contained within BSAs. 

BSA Extraction Cons:

  • BSA assets are now given loose files priority, so this alters the mod author's original design intent and may introduce false 'bugs' that nobody on any forums will likely want to or know how to diagnose or fix ;)
  • BSA extraction in MO happens after loose files are installed. This means that any loose 'hotfixes' would be overwritten by the BSA version, which is outdated. EDIT: this is fixed in the current beta and next release of MO

MO exposes BSA extraction functionality using a prompt when a mod containing a BSA is first encountered. This functionality can henceforth be "always allowed" or selective, based on user preference in response to this prompt. Users that do not fully understand the ramifications of BSA extraction on the specific mods they are using together should not use this feature. If "automatic BSA extraction" is in effect, it can be reset from Settings (click the wrench icon in the toolbar) > Reset Dialogs > click 'yes' at the prompt.
 
First, STEP recommends that users NEVER "always allow" automatic BSA extraction ... why? Because there is no need to do this at all, since the granular functionality already resides within the Archive Tab. More importantly, because many unknown or unintended prioritization issues can come into play as described previously. It is always safer to use the BSA unless it will cause a de facto undesirable result.
 
BSAs that have optimized textures and can be overridden completely by downstream mods should stay inside BSAs (or repackaged using CK's Archive.exe). If assets from inside a BSA need to overwrite some mods and be overwritten by others, then sometimes it makes sense to extract the BSA. MO has a beautiful tool accessible from within its Archive Tab. If a BSA is present in the load order, it will appear in the Archives Tab. Leave it unchecked to allow it to behave normally and be loaded by its plugin (if the plugin is active), and check it to extract the BSA to the mod folder and effectively confer loose-files prioritization.
 
Critics of Mod Organizer and STEP (for Officially Advocating BSA Extraction) 

Some within the well-respected modding community are at odds with the idea of BSA extraction advocated by STEP and facilitated by MO. The most notable contingent is the USkP team. This is relatively old news and nothing that should be shocking, so please do not treat it that way. The reasons are not unfounded and actually valid. I bring this up solely to address the idea to remove BSA-extraction from MO that Tannin suggested if MO-detected load order issues are not resolved properly (by submitting a ticket). In fact, I created this thread to address this one issue as much as to address the knowledge gap that is the real cause of any issues associated with BSA extraction.
 
Some modders are more or less happy with MO's ability to invoke BSA extraction. Generally, mod authors who have gotten a lot of grief with respect to their mods --for problems caused by the ramifications of rampant BSA extraction-- seem to have more of a problem with MO (see note below!). This has been somewhat problematic for STEP and MO with respect to outsiders privy to the argument but not privy to STEP or MO ... never mind that the 'fault' should be shouldered solely by the unwitting mod user for invoking BSA extraction without understanding the ramifications of doing so ... and ours for not properly educating our user base to that effect (hence this thread).
 
Let it be said that the STEP modding community and the vast majority of modders are the kinds of users that use PCs instead of Macs and tend to be somewhat removed from computing 'norms' imposed by Apple and Microsoft and their ilk. In general, we do not like our control restricted in favor of provider control over our resources to make their lives simpler. We are generally in favor of digital freedom, open source software, and the honor system. Big Brother and his methods are generally unwelcome. Demonizing BSA extraction in general and removing it from MO in particular in order to enhance level-of-conrtol by mod providers would be a big mistake, as STEP itself somewhat relies on this feature (and will to a larger extent in the future). However, I think that it is very important that our users understand the ramifications of using BSA extraction, and we need to address explicitly in the STEP Guide.
 
The MO user base (not its 'critic' base) should guide Tannin's direction of MO, IMHO ...  :yes:
 
I want to explore what we do (and do not) know with regard to the ramifications of BSA extraction to our MO users and how best to make MO a broadly accepted utility among all within the modding community ... not just STEP. In order to do so, we must not dredge up combative arguments. Constructive argument is good for all respective modding endeavors, so what has been said in the past is water under the bridge. So keep it lively and fact filled ... but keep it polite and considerate!
 
Please report bugs as Tannin requests using the link above. Also please post to this thread and help us to improve the breadth and accuracy of this OP!

I think BSA extraction should remain in Mod Organizer, but as a hidden feature only. (Activatable via a config file for instance, or usable only in debug mode)

When I first started using Mod Organizer, I was just confused by the option, and it didn't really serve any purpose except increase the risk of messing something up in my install due to the fact that I didn't find any documentation about that feature at the time (and I'm assuming most users don't even look for documentation)

However as a modder, the option is actually very useful for me, as it saves me from having to manually extract a ton of files when trying to make patches, compare versions, or various stuff.

 

I honestly cannot see myself not using the feature now, but at the same time, for regular mod users it doesn't serve any purpose and can instead mess up some features (with fomod installers that install different bsa + loose files, for instance) so it should definitely not popup every time they install a mod.

At first look, that seems to be a rather elegant solution. Hide the feature so that only those into advanced modding are likely to want to find it and can therefore be directed to some kind of agreement that they would have to check a box to show that they understand the ramifications of BSA extraction and accept responsibility for doing so, such information being provided as a prerequisite for checking the box. Like a warranty agreement. Once done the feature becomes activated.

 

Good idea CJ.

(NOTE: This has undesireable ramifications for MO users due to behavior of BSA extraction in MO ... BSA extracts last, so loose file hotfix is overridden by original version within the BSA!)

This behavior is changed with the beta version of Mod Organizer, and with the next release. BSAs during the extraction process will NOT overwrite loose files already present in the beta version.

a few initial comments:

 

"How do BSAs work" misses one of the cases, namely where a mod without a plugin has a BSA. If a plugin is needed to properly handle the BSA then either we need to extract all such BSAs or add extra plugins that are only used to provide an association with a BSA.

 

It's certainly possible to pack the uncompressed optimized vanilla textures back into BSAs using Archive.exe as mentioned in the post (I did some tests on this today). This, and steps involved in getting the BSAs to be recognized are certainly make the vanilla textures optimization process less friendly for inexperienced users. If we do create BSAs with optimized vanilla textures do we remove the original BSAs and use the original names with the revised BSAs  ::O: , or come up with a non-awful solution that doesn't add any new plugins.

 

 

Loose files provides some decoupling of install order and load order. There are a lot of location and quest mods (including some in the REGS pack) that include replacements for vanilla textures, meshes, and scripts. In some cases, if BSAs are used for the resources vs. loose files, there can be no load order that provides the proper overwrites.

Agree/disagree. Two years ago or whenever I started using MO, I remember suggesting an "Advanced Mode" checkbox for the Settings window. In Advanced Mode, the user would be able to access the less commonly used features of MO. In the default mode, MO would be simplified and streamlined for the average mod user.

@DoubleYou (and Tannin or whomever)

I am afraid that I am still not clear on how MO handles BSAs. If I take the explanation about BSA priorities in the MO guide, then

  • It would seem that MO can prioritize BSA content (as a solid block of assets) according to the install prioritization rather than the plugin prioritization, thus, decoupling a BSA from its plugin.
  • When a BSA in the Archives Tab is checked, it allegedly loads according to install prioritization, but if it is unchecked, it is loaded according to its plugin prioritization ... this does not jive at all with the caption on the bottom of the Archives Tab window ("Marked archives ( :!:) are still loaded on Skyrim but the regular file override mechanism will apply: Loose files override BSAs, no matter the mod/plugin priority"); I only get the :!: symbol if the BSA is unchecked and has a plugin that is checked in the Plugins Tab. Otherwise, the BSA is either checked or unchecked. Furthermore, right clicking the BSA provides an option to extract. Finally, dummy plugins used only to load a BSA are potentially redundant, but otherwise not. This is all very confusing, so we need a very clear explanation of the four scenarios and if any of the four scenarios following do or do not apply if extract is/is not used AND/OR if the plugin is a dummy or not:
    • Plugin checked, BSA checked - ?
    • Plugin checked, BSA unchecked - :!:  ... ?
    • Plugin unchecked, BSA checked - ?
    • Plugin unchecked, BSA unchecked - ?
  • Is checking/unchecking in the Archives Tab an alternative to BSA registration or is this effectively accomplished by registering the BSA in Skyrim.ini?
  • Does MO scan BSA archives and include the asset conflict information in Mod-Right-Click > Information > Conflicts?

I am not aware of any mods that do not have a plugin along with the BSA ... that is kind of a no-no isn't it?

If we package any optimized vanilla assets and pack them in a BSA, as you mentioned in the OP, then this would happen. If all mods without plugins are loose files, then at installation time across all the mods we will have some with loose files and some with BSAs (and some with both). We can't have both plugin order and installation priority determine resource installation order since the resources from plugins and resources from loose files are not fully separable. Do all of the loose files that are not associated with a plugin install before or after all the loose files and BSAs associated with plugins, or is there a way to intersperse non-plugin resources and plugin-based resources using a combination of installation priority and plugin order?

 

Best practice for vanilla texture optimization (or any texture optimization) is to extract the BSA, delete all non texture folders and continue using the default BSAs. The loose vanilla textures can then be loaded up near the top of the install priority where they will overwrite the original within the BSA and be overwritten by all other downstream mods. The exception is when there are other BSA downstream textures that should overwrite vanilla. These would then need to be extracted

This is why we need to extract the USP BSAs today

... or, we could recommend repackaging all vanilla textures into a custom BSA and provide a special loading plugin ourselves.

This custom BSA isn't trivial to construct (Its more work than the current optimized texture archives), and it may need to be several to keep the BSA from becoming too large. Still, it might be the best answer if we want to minimize BSA extraction needs.

Once STEP is fully installed (especially with the Vano89 optimized vanilla HRDLC) there is not that much gain from vanilla texture optimization anyway.

There are over 11500 optimized vanilla textures in the optimized STD alone that are not overwritten by other mods; at least half of these have been changed by DDSopt. There are roughly 9000 textures from the optimized HRDLC that are not overwritten by other mods. There are only a small number of textures in the DLC BSAs that aren't overwritten.

Just as Vano89 provides the optimized HRDLC, we could provide just our DDSoptimized vanilla textures (including HRDLC textures) packed within a BSA and including a plugin loader. Or we could use an INI tweak to add it to the end of the BSA reg list in Skyrim.INI ... ?

 

It is about time somebody provided a comprehensive set of vanilla optimized textures anyway.

If we can do this legitimately it would save a lot of work for users as well as STEP staff We could potentially even ignore the DLC BSAs since so few of these textures aren't overwritten.

 

The STD.bsa with optimized vanilla textures is roughly 1.27 Gb, by the way. The BSA was created with Archive.exe .

Regarding BSA extraction in MO: I've decided to move this functionality into a plugin that will by default be disabled. This means an advanced user who wants BSA extraction can enabled it and use it as he always has whereas someone who doesn't know about BSA extraction will not be confronted with the choice at all.

Regarding BSA order vs Loose order in MO:

  • MO totally "messes up" this concept, just throw out everything you've read about BSA vs. loose order, it doesn't apply to MO.  In MO, (if you check all bsas in the archives tab) all BSAs are registered BUT if a BSA has higher installation order than a loose file that loose file doesn't appear in the VFS. This means assets are effectively loaded in installation order no matter which format they are in!
  • This also means that no matter if you extract BSAs or not, the bsa order will never be automatically matched to your plugin order!
  • Therefore you have to have to have to follow MOs suggested installation order in the warnings window (Potential mod order problems) to ensure a stable game.

When I suggested I might remove BSA extraction I was also thinking of removing the behaviour in 1, because then we could drop mod order suggestions as well -> loose one feature, get rid of one issue, drop tons of complicated and confusing functionality.
 
More BSA Pros:

  • Better performance (a lot of files also slows down game startup, especially when using MO)
  • Less disk usage (because BSAs can be compressed)
  • Faster installation (you save yourself the extraction step)
  • Removes user-control (yes, this is a good thing, at least for mod authors and myself ;) )

 

 

 

The MO user base (not its 'critic' base) should guide Tannin's direction of MOIMHO ... :yes:

I always tried to be guided by reason... If the critic base has the better arguments then they're who I'll listen to.

Um... so, just to be sure I understand correctly. What you're saying is that if we install a mod that adds files in a loose file format it won't matter that we did so because the .bsa containing the same files takes priority? Please correct me if I'm wrong (I am operating with a headache and need to go to bed but that's what I'm reading atm).

 

At ESRB I'm fairly certain it is allowed or at least it's a grey area; I doubt they could prevent us from uploading them somewhere (so long as we say where the came from) without changing their TOS and End-User agreements.

MO is different and more clever than I realized. BSA extraction would seem to only be needed in some unusual cases where a mod has a BSA with some resources than need to be hidden so they don't suppress those resources from another mod that is lower in the installation order.
