Fallout 4 Optimization and Performance Systems Explained


Recommended Posts

How does one go about finding out exactly which mods need Precombined and pre-vis regenerating, Obviously not every mod in my load order will need it but I'm curious if master files need this process done too, I'm checking for files that break previs by following RRTV's video but I'm not sure what to do with the information I get at the end of it all as some mods will be or have been overwritten by others, so in that sense what does a user do, this is more of a generalized question but for the sake of information I shall say I think I found a couple of broken precombines in Sim Settlements but I know it's a master and gets overwritten by other mods, in such circumstances what should the average user do

 

Any help ?

On page 21 zilav explains how to filter for broken pre-combines with xEdit. Vlits also says how you can see them in xEdit by looking at them but didn’t see what page it was on. Yes this thread is long but it’s full of good information.

Warning:

 

This is a long and technical post but I feel it's appropriate given that it's a long and technical thread. If you're wondering what all the funky commands I'm typing are it's because I use Cygwin on all my windows boxes. 25 years of Unix will do that to you.

 

Good news:

 

I have a pretty good idea of how Bethesda's "automated process" is utilized for batch precombine/previs generation and the CK we use has access to this functionality. We can use this functionality to regenerate PC/PV for only the altered cells in a single master, single plugin, or even multiple plugins (with a little bit of work) without clicking on a single thing. It can also be used to regenerate PC/PV for the base masters based on loose file overrides or associated archives (with a bit of gaming of the system). On top of that it can also generate said precombine data at the same small filesizes the vanilla precombines have.

 

Bad news:

 

I can't get any of the output it generates to actually work in the game (sans previs which technically should work) even though the approach I'm using appears sound.

 

Background:

 

For a while now I've been playing around with various flora mods like Rustbelt but with a completely empty esp so as not to introduce any PC/PV breakage into my game but still use some of the swapped textures. Related to this I also started looking into regenerating precombines/previs with CK for all my mods that modify the world in some way (not even really worrying about any conflicts, just trying to get it work) using various ways to try and game the system (uGrids=11 or higher). No matter how I skinned it the approach was always very tedious (less so with precombines) and in certain aspects it simply felt unreliable. Even after regenerating PC/PV for 200-300 cells I'd still see random issues like the resultant saved plugins missing either XCRI or XPRI data seemingly at random and it was obvious it would not scale. This was in addition to the extremely annoying way CK interfaces with previs generation such that if you touched anything the interface would basically lose it's mind and play focus games with other windows, outright stall, or otherwise turn into an event loop blocking mess. As an OG unix hacker who does automation for a living this was something that I could not stand and set out to look for better ways.

 

Goals:

  • The ability to generate PC/PV for an entire load order with the least amount of hassle.
  • The ability to generate PC/PV for a specific plugin or set of plugins with the least amount of hassle.
  • The ability to generate PC/PV at filesizes similar to the vanilla game files.
  • The possibility of making it all work in a way that people could pragmatically do it as an infrequent multi-hour batch job after they make major changes to their load order (for things involving cells only).

 

Issues:

 

As it is, generating PC/PV for an entire worldspace on an existing load order isn't actually all that difficult. While there are unfortunate issues with CK outright crashing during it (which is quite painful given that it usually takes a few hours to do), the main dealbreaker is previs generation. CK simply just does not offer any kind of reasonable way to regenerate previs for those same precombines with the provided UI. Sure one can play uGrid tricks or write elaborate autohotkey stuff but in the end it's one giant unreliable hack of an approach. On top of that anything involving a mod that alters multiple cells in various parts of a worldspace (but not the entire worldspace) places a huge amount of load on the mod author to keep track of all their altered cells (something CK could easily do) and a ton of extremely tedious manual labor just to generate the resultant data (and this is ignoring the future conflicts with other worldspace mods). We all know there is no way BGS or any other commercial entity would put their own people through this process for something so mechanically trivial, yet here we are.

 

Approach:

 

One of the things I noticed with the various BGS documentaries out there now is just how much CK is used for their in house development and also just how much functionality is in the tool that's released to modders. I knew in the back of my mind that it was unlikely they would have a totally different CK just for independent individuals to use and the more I used it the more I started to suspect that it had more functionality that wasn't exposed. So the first thing I had to do was start looking at the binaries for things like command line options or INI settings that weren't otherwise documented. That's where strings comes in. For those not familiar, when you're working with a binary you suspect has command line functionality that's not documented the first thing you do is run it with -?, /?, -help, /help, etc. If it's uncooperative or otherwise doesn't have default usage output, there's no need to break out IDA Pro and start disassembling it, you simply run strings on it to extract anything interesting out of the .data segment of the binary. Which leads us to...

Still on the large side compared to vanilla. But what about those clean vs filtered options? Let's regenerate:

That's more like it. But how was it that the vanilla files were even so small in the first place? Clearly if they're not baking in all of the mesh information into each precombined NIF (the equivalent of inlining if you will) they've got to either be doing more work at runtime or storing that information elsewhere (time vs space). One thing I noticed that was on completion of -GeneratePrecombined two files are created:

  1. CombinedObjects.esp (the actual XCRI data for the run).
  2. "<esm> - Geometry.psg" (a binary data file).

Recognizing the '- Geometry' fragment as being part of an INI value I've seen before, I go back it:

clayne@a4-sfx:/cygdrive/c/Program Files (x86)/Steam/steamapps/common/Fallout 4.pctest $ egrep '- Geometry' Fallout4_Default.ini
SGeometryPackageList=Fallout4 - Geometry.csg

But how does one get from "Fallout4 - Geometry.psg" to "Fallout4 - Geometry.csg"? Simple, the -CompressPSG option. Here's an example with DLCworkshop01.esm because it's small:

clayne@a4-sfx:/cygdrive/c/Program Files (x86)/Steam/steamapps/common/Fallout 4.pctest $ ./CreationKit.exe -GeneratePrecombined:DLCworkshop01.esm clean all
clayne@a4-sfx:/cygdrive/c/Program Files (x86)/Steam/steamapps/common/Fallout 4.pctest $ ls -la Data/DLCworkshop01*.{csg,psg}
-rwxrwx---+ 1 clayne None  5824 Aug  2 14:21 'Data/DLCworkshop01 - Geometry.csg'
-rwxrwx---+ 1 clayne None 23240 Aug  9 01:06 'Data/DLCworkshop01 - Geometry.psg'
clayne@a4-sfx:/cygdrive/c/Program Files (x86)/Steam/steamapps/common/Fallout 4.pctest $ mv 'Data/DLCworkshop01 - Geometry.csg' 'Data/DLCworkshop01 - Geometry.csg.orig'
clayne@a4-sfx:/cygdrive/c/Program Files (x86)/Steam/steamapps/common/Fallout 4.pctest $ ./CreationKit.exe -CompressPSG:DLCworkshop01.esm
clayne@a4-sfx:/cygdrive/c/Program Files (x86)/Steam/steamapps/common/Fallout 4.pctest $ ls -la Data/DLCworkshop01*.{csg,psg}
-rwxrwx---+ 1 clayne None  5820 Aug  9 01:08 'Data/DLCworkshop01 - Geometry.csg'
-rwxrwx---+ 1 clayne None 23240 Aug  9 01:06 'Data/DLCworkshop01 - Geometry.psg'

And there you go, a csg file, just like all the others:

clayne@a4-sfx:/cygdrive/c/Program Files (x86)/Steam/steamapps/common/Fallout 4.pctest $ ls -l Data/*.csg
-rwxrwx---+ 1 clayne None 100938421 Aug  2 11:49 'Data/DLCCoast - Geometry.csg'
-rwxrwx---+ 1 clayne None 104296054 Aug  2 11:49 'Data/DLCNukaWorld - Geometry.csg'

-rwxrwx---+ 1 clayne None 240043177 Aug  2 11:49 'Data/Fallout4 - Geometry.csg'

Starting to become more clear now. But what are psg, csg, or even "SGeometryPackageList" for that matter? Well a bit of brain-storming based on the fact that we're dealing with geometry and NIF files that seemingly get away with being much smaller than what we're used to seeing, plus a tool which generates psg files for us, and it becomes clear that 'sg' has to be about shared geometry.

BSPackedCombinedSharedGeomDataExtra, BSStaticTriShapeDB, CsgStream@BSStaticTriShapeDB. It seems pretty clear to me that 'psg' (and the compressed counterpart 'csg') files are a shared database of triangle meshes that the game is able to use with the "clean" NIFs that the vanilla game ships with and which -GeneratePrecombined:<esm> clean also generates. The reason CK doesn't generate these smaller NIFs by default is because it would require modifications to the shared geometry database for each esp which overrides XCRI data for a given master's cells and has it's own precombines. Clearly it would be unreasonable to modify the game's shipped files for most people and there might not have been code in place to handle per-plugin csg's (although that facility exists per-master) in the same way precombined NIFs are with loose files or archives (as the filesystem or archive acts as a DB itself).

 

Aside from the csg file there's also that CombinebObjects.esp file. Obviously this file is important as even though one generated new precombine meshes they still have to tell the actual game to use them correctly. As one would expect it's purely XCRI overrides which are meant to be merged back into the master (although technically that's not strictly required) via version control, i.e. the way BGS does it in house. The way I approached it for my testing was creating an xEdit script based off one of the existing ones to simply merge PCMB/XCRI changes back into masters (I also created a similar script for VISI/XPRI/RVIS).

 

Previs:

 

Okay, so what about previs? How does that get handled? Easy:

What about file sizes compared to vanilla?

After UVD files are genearted a PreVis.esp plugin is generated. This contains VISI/XPRI data, similar to how CombinedObjects.esp provided PCMB/XCRI data and is meant to be merged into the associated master or otherwise combined into a plugin with the XCRI data.

 

There's also cdx files and -BuildCDX:<esm> which as far as I can tell appears to be dependent on XCRI data. However, I can't tell if it's an index for the shared geometry databases or if it's a more general cell index used for preloading resources of some sort. I've left some speculation in my notes as I just don't know enough about them yet.

 

 

Major Issues:

 

Okay, everything's great right? We can now just merge a bunch of worldspace mods, write a bunch of bat files, hack up some xEdit scripts (or enable version control and use plugin merging), and we're good to optimize entire load orders overnight right? Wrong (well, kinda, previs will probably work). Many of the NIFs generated by -GeneratePrecombined result in a CTD upon loading a save. Simply even having the NIFs in Meshes/Precombines will cause the issue, a plugin doesn't even need to be involved. I ran fo4 in a debugger and the backtrace I got was:

(be8.35ec): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.

A useful reference I found on flex that references this function: http://www.simoncoenen.com/downloads/flex_paper.pdf:

 

 

The last parameter except for the amount of shapes and the FlexMemory, is an array of shape flags. Since the FlexCollisionGeometry has the flexibilty to be different kinds of meshes, the flag tells the solver what kind of shape the user intends to use. A flag can be created with the helper method flexMakeShapeFlags(). It takes in an extra bool telling if the shape will be dynamic or not. In the case of a triangle mesh, the method looks like this:

int flag = flexMakeShapeFlags(eFlexShapeTriangleMesh, false)

At this point, all the data is obtained and can be passed to the solver and used in the simulation.

 

Honestly, I'm not even certain flexMakeShapeFlags is really the issue (given that I don't have a debug build, a real symbol table, or any of the source), but one would be unwise to ignore the correlation with triangle mesh involvement which this function has.

 

On top of that, no matter how many incantations of -GeneratePrecombined I did, either with clean or filtered, I could not get NIFs that were exactly the same for every single precombined mesh. I could get *some* that were the same, but most of the files had md5sum differences and hexdump examination showed header strings (things like embedded export paths), but I kept seeing minor block differences when checking vanilla data against the generated NIFs. Sizes would be very similar but there would always be some sort of minor difference that looked innocuous on the surface but never the less, CTD at save load every time. This goes for precombined meshes generated with CK vs -GeneratePrecombined filtered (i.e. both "full size") or extracted vanilla precombined meshes vs -GeneratePrecombined clean. Related to this, anytime I tried to use -BuildCDX to generate the CDX database I would always see Havok related errors like:

HAVOK:                          Binary Packfile has the wrong endiannes or pointer size. Predicates won't be read.
HAVOK:                          bhkPhysicsSystem::LoadBinary - nullptr system data found.

HAVOK:                          bhkNPCollisionObject::LinkObject : invalid system data found - pruning object from scenegraph.

If I simply nuked my generated precombines entirely (so that the archived versions would be used) and ran -BuildCDX again I would *not* get these errors. For smaller CDX files where I didn't start running into issues with cached file limits (CK was emitting these) the CDX files would be nearly the same size. But this makes me weary. Another thing I noticed were that the vast majority of vanilla NIF files have export paths with suffixes of .hkt, e.g.: 'g:\_F4\DLC01\Art\Raw\CombinedMeshes\PreCombined\0004280D_D495E0D3_OC.hkt'

Clearly there's some kind of havoktools involvement in play here and it makes me think there could be a connection to the Havok errors I see when using -BuildCDX and meshes from -GeneratePrecombined files. I can certainly understand why havoktools would be involved with the normal meshes that makeup a combined mesh but I'm not certain why they would be involved with seemingly already generated precombined data that originated as hkt files.

 

What's particularly maddening here is that generating precombines from *within the UI* doesn't present the CTD issue. There's absolutely no way the codepaths used for generating the precombine data is different for the BGSAutomatedProcesses route vs the interactive UI route. Developers would have to go out of their way to do that and it wouldn't benefit anyone. There has to be something else going on as I've isolated problematic precombine generations to just a single NIF file which if placed in Meshes/Precombines will CTD the game. Said NIF file looks normal in NifSkope (for a precombined one atleast) but I really need a NIF expert to look at it (said expert being @jonwd7).

 

 

Assorted Notes and Speculation:

 

  • Running in a debugger produces additional debugging output during -GeneratePrecombined and -GeneratePreVisData (CK, unknown for fo4). You see this particularly with BSMeshCombiner output. This happens because CK does a check for IsDebuggerPresent().
  • On my 8700k w/ 32GB of RAM I can generate precombines for all of Fallout4.esm in under 2 hours. Previs is probably around 5-6h, but I never made it that far after getting obsessed with the precombined NIF CTD issues. Unless you have 64GB of RAM a pagefile is highly recommended as CK shoots up to ~48GB virtual near the end of a precombine run (actual resident usage isn't even close to that).
  • Use of -GeneratePrecombined does not create a PS4 subdirectory like it does when using CK (said subdir contains basically the same data as Meshes/Precombines).
  • -GeneratePrecombine and -GeneratePreVisData will generate data *only* for cells that having static meshes that could be combined. This is a big deal because it means one can simply pass a plugin arg (and I absolutely tested that esp files also work with these modes) and only cells within that plugin will be generated. Doing this in CK is an utter hassle - especially when it comes to previs.
  • CreationKit.ini settings which matter:

iMaxUmbraBakeThreads=<n> (default: 4 - I use 16 as 4 wasn't fully utilizing the cpu).


bExportSceneOnUmbraGenerate=0|1 (default: 0): Instructs the previs generator to export .scene files into Vis/Scenes (scene files are what are provided to Umbra. Related: https://support.umbra3d.com/hc/en-us/articles/213893645-1-7-Exporting-your-scene-into-the-Umbra-3-Scene-format


bExportTomeOnUmbraGenerate=0|1 (default: 0): Instructs the previs generator to export .tome files into Vis/Scenes (tome files are what Umbra produces - and as far as I can tell what UVD files actually are). Related: https://support.umbra3d.com/hc/en-us/articles/213899805-5-7-Computation


bGeneratePreCombinedGeometryPreVis=0|1 (default: 1): Fairly certain this instructs -GeneratePreVisData to force use of precombined rather than normal meshes for previs (i.e. "generate visibility vs generate precombined visibility"). I've also done A/B testing which verified different debug output from Umbra.

bForcePreCombinedObject32bitExport=0|1 (i'm not sure if this makes a difference, nor do I know the default [but I'd think a safe bet is 0])

  • Use of -GeneratePrecombined:<esm> with the filtered option produces "full size" combined meshes *unless* a PSG is already present then it seems to behave similar to clean. I also believe 'filtered' is the default because if one attempts to use -GeneratePrecombined:<esm> all they'll get a usage error - which leaves only clean and filtered as viable options. Without any options -GeneratePrecombined:<esm> produces the full size non-shared NIFs.
  • -GeneratePrecombined's currentset and totalset appear to be some kind of sharing/batching options. Haven't experiemented with them much and I'm not sure how they'd work with the clean option given a single psg file output.
  • fAccurateOcclusionThreshold (default=768?) and fSmallObjectSize? (default=100?) -> https://support.umbra3d.com/hc/en-us/articles/115001763033--Accurate-occlusion-threshold-and-visibility-data-LOD-in-depth
  • 3x3 uvd/vis cell grids also related to this? https://support.umbra3d.com/hc/en-us/articles/214115985-Introduction-to-Streaming
  • At one point (due to debugging output for BSMeshCombiner being similar when using -GeneratePrecombined and -GeneratePreVisData) I thought that -GeneratePreVisData was computing precombines on the fly and that existing XCRI or NIF data didn't matter, but after nuking them entirely (even archive files) and trying a -GeneratePreVisData run I saw:
MODELS:                         Could not find model PreCombined\DLCworkshop03.esm\00000F31_BC12197D_OC.NIF

MODELS:                         Could not find model PreCombined\DLCworkshop03.esm\00000F31_BF536538_OC.NIF

Which indicates that there is a dependency on these meshes being present and that precombine computation (within the context of generating previs data to hand off to Umbra) still requires the precombined NIFs. Somewhat surprising because in a way it makes sense for the previs side to simply recompute the data at generation time for a small efficiency hit but without the dependence on XCRI data being accurate. What's still odd though is that the debugging output clearly shows BSMeshCombiner combining even when -GeneratePreVisData is being used.

  • -BuildCDX/cdx files appear to be dependent on psg/csg data, XCRI, and/or precombines in general. The main ini also references them as:
  SCellResourceIndexFileList=Fallout4.cdx
  • CDX appears to be a database index for cells (computed via -BuildCDX:<esm>) for which precombined/XCRI data is referenced by. This appears to be related to preloading cell data but could also be an actual index for the csg/psg shared geometry databases. A class which seems to line up with this is BGSCombinedCellGeometryDB::CDX::PsgBatchIter which implies the CDX file is involved with the packed shared geometry file (<x> - Geometry.psg [compressed via -CompressPSG:<esm> into a .csg file]). Related classes: BGSCombinedCellGeometryDB::ModelDB, namespace for the functionality seems to be BGSCombinedCellGeometryDB.
  • CSG is definitely some kind of compressed packed shared geometry (.psg) database which class names like BSStaticTriShapeDB::CsgStream line up with. On completion of precombine generation with -GeneratePrecombined:<esm> clean all CK will write an "<esm> - Geometry.psg" file (which is later compressed to .csg with -CompressPSG:<esm>). Other related classes: BSStaticTriShapeDB::Builder, BSPackedSharedGeometryBuilder, BSStaticTriShapeDB::IBatchRequestIter, BGSCombinedCellGeometryDB::CDX::PsgBatchIter.
  • To compress PSG to CSG, use -CompressPSG:<ESMFilename> (must use -GeneratePreCombined with clean option).
  • Notes on tree branches, shrubs, and other semi-transparent occluders when it comes to previs: https://support.umbra3d.com/hc/en-us/articles/213893645-1-7-Exporting-your-scene-into-the-Umbra-3-Scene-format
  • Umbra divides scene objects into occluders, which can hide other geometry, and targets, which can be hidden by occluders. Any object can be an occluder, target or both. ‘Bad’ occluders, such as fences, grates and other objects that do not generate good occlusion, as well as transparent objects should not be set as occluders, but as targets only. A good rule-of-thumb is to set everything as both occluder and target by default and then remove the occluder flag on a per-need-basis.

 

  • Implied reference to precombining objects from Umbra:
  • Small objects that are cheap to render – such as props – and that are typically visible at the same time can be grouped together. An example of such grouping is a table with all the small items on top and the chairs around it. In the below picture there is an example where every pillar in a room is grouped together as a single object because they are almost always seen together.

Regarding the CTD when generating "clean" precombines:

 

Did you monitor file accesses with procmon while doing that? I have a sneaking suspicion that this might depend on the Havok toolkit being present given how it spews Havok-related "stuff's missing, yo!" errors when put to the test while generating CDX. Theory would be that this process changes how the _Physics.nif is baked and that this relies on Havok toolkit to fill the bhkPhysicsWhatever node in the NIF file.

 

Another experiment would be generating with the "clean" parameter, tossing the _Physics.nif of that generation run and instead using the archived _Physics.nif for CDX generation. In practice, this would only be useful for mods like Boston FPS Fix that don't change placed refs. But it might tell us something about how CDX and precombination interlock.

 

Sounds a little convoluted reading it again but I think you get what I mean.

 

In addition, this was a surprisingly interesting read. Do you by chance write technical documentation for a living? If not you should consider it. ;-)

I just did a -GeneratePrecombined and -GeneratePreVisData run with a test esm (adds a few trees to a couple of cells) where I looked for anything havok or hkt related in procmon and didn't see anything, although I did see the Havok related endianness and pointer errors again with both -GeneratePreVisData and -BuildCDX. It seems once the generated precombined NIFs get utilized by the engine during cell processing the errors come up (it's not actually BuildCDX specific as I thought before).

 

I then cleaned everything up, did per-cell precombines from within CK, exited, and did a -GeneratePreVisData:treetest.esm clean all and absolutely none of those havok related errors. From a logical standpoint clearly CK knows how to generate things correctly, but something is missing here with -GeneratePrecombined, specifically. I even did the non-'clean' versions of precombines (i.e. the equivalent to what CK does from the UI) and they still result in the same havok related errors when generating PreVis, whereas the CK generated ones do not.

HAVOK:                          Binary Packfile has the wrong endiannes or pointer size. Predicates won't be read.
HAVOK:                          bhkPhysicsSystem::LoadBinary - nullptr system data found.
HAVOK:                          bhkNPCollisionObject::LinkObject : invalid system data found - pruning object from scenegraph.

I spot checked a few of the files with mismatching sums but same sizes and they appear to just be ordering differences of different blocks within the file. As far as the physics files go, from the surface level it's not like the sizes are terribly different and I see similar data patterns in the actual files so I have to presume the same ability to orient or produce the data is present in both methods but something is clearly acting differently here. I've uploaded these generated files to this location:

 

http://www.anodized.com/~clayne/fallout4/pcpv/

 

There's also a precombined NIF in there from an earlier generation which was isolated down to a single file that CTDs the game if placed in Meshes/Precombines.

 

Another experiment would be generating with the "clean" parameter, tossing the _Physics.nif of that generation run and instead using the archived _Physics.nif for CDX generation. In practice, this would only be useful for mods like Boston FPS Fix that don't change placed refs. But it might tell us something about how CDX and precombination interlock.

 

Heck one could actually use the CK generated _Physics.nif file as well and achieve the same effect (remember those ones don't throw havok related errors). There's still the instant CTD on savegame load issue with some of the non-Physics NIFs though. That seems like a more dire issue.

 

In addition, this was a surprisingly interesting read. Do you by chance write technical documentation for a living? If not you should consider it. ;-)

 

Thanks. I don't do technical writing specifically, but I've done enough profiling, debugging, and troubleshooting of convoluted situations in a professional capacity over the years to know what information is valuable and what isn't I guess. With these types of problems one also has to maintain a certain adherence to scientific method so as not to muddy the results as well.

 

BTW: That tip of the hat to stdio and sysctl in PIRAD's holotape didn't go unnoticed. :thumbsup:

Try to regenerate with enabled Version Control, who knows. CK does some things differently when VC is enabled.

 

 

Tried that and didn't see any significant difference. Even all the generated NIFs were exactly the same size with bUseVersionControl=0 vs 1. Currently sanity checking loose files vs archives but I'm pretty sure I did that a while ago and it doesn't seem like it'd really make a difference.

On my 8700k w/ 32GB of RAM I can generate precombines for all of Fallout4.esm in under 2 hours. Previs is probably around 5-6h, but I never made it that far after getting obsessed with the precombined NIF CTD issues. Unless you have 64GB of RAM a pagefile is highly recommended as CK shoots up to ~48GB virtual near the end of a precombine run (actual resident usage isn't even close to that).

 

Finally got around to doing this with CK UI generated precombines (still haven't resolved the other issue with -GeneratePrecombined ones). First and last lines of U3D output from -GeneratePreVisData:Fallout4.esm clean all:

[05:04:48] INFO: Umbra 3 Optimizer version 3.3.22  (build: 58bc48d2405823a0d92fca7d7a5dac9d02e0a94b)
[..]
[08:27:55] INFO: created tome with 1 tiles, 42 targets and 0 gates

So about 3.5 hrs, give or take, for around 1000 3x3 cells or 964 uvd files (not all cells produce output) on my box (w/ a little under 2h for the world precombines). This host has 32GB of RAM and whilst not all physical RAM ended up being used there were definite periods of near 100%. However that was just physical; don't underestimate the need for a significant pagefile as there's some kind of leak present (or something else going on) that really cranks up when the run gets to the interior cells. At peak usage CreationKit.exe was around 85GB commit size (i.e. virtual rather than resident) and if you don't have a large enough pagefile the run will simply crash about 80% of the way through. A 64-96GB pagefile should cover it depending on your RAM.

 

 

 

Getting the output to actually work in the game requires merging in the produced PreVis.esp to a master. In my case since I'm working with a copy of Fallout4.esm for experimental purposes, I simply merge it in via CreationKit.exe -checkinplugin:PreVis.esp Fallout4.esm in my dev directory. Also, don't try this with the all the generated precombines as loose files as CK has an internal 32k handle limit (you'll see the warnings) that will crap out the run about 25% of the way in.

So, I am wondering if you are updating the Timestamp for the Precombine, and previs files you are generating with this process inside the plugin? The game will ignore any precombine and previs file if the timestamps don't match with the plugin. I might have missed where you explained that.

The automated process handles that. Both the CombinedObjects.esp and PreVis.esp files produced by -GeneratePrecombined and -GeneratePreVisData include data updates for (PCMB, XCRI) and (VISI, XPRI, RVIS) respectively. In a nutshell, for the full-size non-shared precombines (the one CK produces now) the process looks like this with version control:

  1. CreationKit.exe -GeneratePrecombined:<esm> filtered all
  2. CreationKit.exe -CheckinPlugin:<CombinedObjects.esp> <esm>
  3. CreationKit.exe -GeneratePreVisData:<esm> filtered all
  4. CreationKit.exe -CheckinPlugin:<PreVis.esp> <esm>

 

When using the 'clean' or shared precombines (the ones that BGS generated):

  1. CreationKit.exe -GeneratePrecombined:<esm> clean all
  2. CreationKit.exe -CheckinPlugin:<CombinedObjects.esp> <esm>
  3. CreationKit.exe -CompressPSG:<esm>
  4. CreationKit.exe -BuildCDX:<esm>
  5. CreationKit.exe -GeneratePreVisData:<esm> clean all
  6. CreationKit.exe -CheckinPlugin:<PreVis.esp> <esm>

 

It's possible that in the 2nd form steps 3-4 can occur at the end, but I know -BuildCDX uses cell data and acts in concert with the <esm> - Geometry.csg (uncompressed: psg) file produced by the first step.

 

Note: There's an issue where -GeneratePrecombined with either clean or filtered options produces NIFs that aren't compatible with the game due to 32-bit Havok data being used. This is a major issue that's still unresolved but IMO solvable as CK already knows how to do the right thing from the UI. -GeneratePreVisData should be unaffected as it's basically a wrapper around BGSAutomatedProcess which calls the Umbra3d optimizer. The latter part is still beneficial as easily the most tedious part of working with this data is regenerating previs from within the CK UI. However, if you're working with a long list of specific cells (e.g. @chucksteel and BTI), then generating precombines from within the UI is also quite tedious. When you use the automated commands they look at cell data of the passed in esm or esp files and only process cells that contain statics - which is way less tedious then attempting to do the same thing for 50 cells in CK's UI (as there's no way to filter by plugin owner plus too much menu/mouse/human involvement).
