okay next problem lol it pops up "completed successfully" (this popup comes from skyrim not from MO2) but I can see in the skyrim window that Tamriel only reached 71% is this sort of thing normal? am I going to be missing loads of grass if it hasn't reached 100%?

managed to enable all my mods and it's working fine, the only one I've had a problem with is "northern roads - floating plants fix.esp" from NR patches compendium. for some reason with this enabled, the grass generation starts but then ends a couple of seconds later with a popup saying it's finished successfully. not sure if this patch affects the grass or not but happy to leave it disabled for now and see what happens, everything else is enabled and working fine

okay I'm getting somewhere I'm using rootbuilder - turns out this causes problems here unless you add precachegrass.txt to its exclusions since doing that, the game still crashes instantly when I start to generate grass with mods enabled, but then MO2 restarts it and it continues from where it was. it seems that previously it was starting from scratch every time because rootbuilder was interfering with this file, so it would crash right at the start and then MO2 would just say "grass cache finished successfully" and that would be it. so it just appeared to be getting nowhere at all. it's actually progressing now

ah yes I am using grass cache helper NG during generation as well, but I have tried disabling that and changing settings manually so I could be certain what was going on. I have the base set of mods (skse, address library, etc) all running and initially I had all my mods enabled, but I've since disabled anything that doesn't affect grass or terrain to try to track down what's causing the problems, and then started disabling those as well to try and figure it out. so far, it seems that if I enable any mods that include terrain edits (landscape fixes for grass mods, northern roads, etc) then Tamriel generation exits immediately, but if I disable those mods then it works. ideally I want to generate grass with those enabled though!

I am yes, and if I enable any of the terrain-editing mods (landscape fixes, northern roads, etc) then the game loads up but then exits immediately, before any grass generation happens, and the pop up says "grass generation finished successfully". if I disable those mods then the grass generation works

right I've changed my OnlyPregenerateWorldSpaces so it only generates for Tamriel, to assist debugging if I turn off every mod then it will generate the Tamriel world turning the few mods I'm using back on one by one, and it seems that if I enable any mod that modifies the terrain then it's instant crash as soon as cache building begins. so that's cutting room floor, landscape fixes for grass mods, landscape and water fixes, and northern roads. any of these enabled and it's instant crash, but without any of these then it works. of course if I generate the cache without these and then use it, the grass will be cached to the wrong terrain unless I remove those mods permanently...

actually one thing I've just noticed is there's no files whatsoever in my cache that begin with the word "tamriel" there's 2000 files there and I can see files for all the different worlds listed in "OnlyPregenerateWorldSpaces", except for Tamriel. that's bad isn't it

ongoing grass cache issues again. thanks for the help so far! I've got the grass cache generation apparently working - it takes about 25 minutes to complete, and if I open the console I can watch it progress through the 38 worlds it generates for when it's finished the game crashes (of course) and the files are in MO2 overwrite folder, over 2000 CGID files so it looks good, so I save that as a new mod. all good however there are two problems first, the cache is really small. most reports online suggest it should be several GB, mine is only about 200MB. so it's not zero, but it doesn't seem anything like as big as it should be second, absolutely no grass appears in game if I try to use it. I don't know if this is because the cache has little/no grass in it, which is why I can't see any, or if it's because there's something wrong with loading it I'm using Veydosebrom with the "dense" preset, and I've found that when enabling NGIO I need to enable "super dense" mode in NGIO ini to maintain the same amount of grass visible in the game, as when the mod is disabled. so that's enabled. for some reason, all areas of grass just get a little depleted when it's enabled and super dense mode seems to fix it here's a screenshot of a test play using the settings I'm building the grass cache from (so most mods disabled except for grass/landscape mods and relevant patches, resolution down to 1200x720, etc) with NGIO enabled, but the settings "UseGrassCache = false" and "OnlyLoadFromCache = false", so that I can play the game and see how it should look. as you can see, plenty of grass I then set both of those settings to "true" and build the cache, which as I said takes about 25 minutes and ends up with a cache of about 2000 files adding up to about 200MB of data I then enable the cache and enable Grass Cache Helper NG and get absolutely no grass. nothing. completely barren. I've tried this with and without NGIO enabled and it's the same either way. I do not have Seasons of Skyrim, which the Grass Cache Helper NG page suggests can cause this, so it can't be that I've built the cache 4 times over now, trying a few different things, and it's coming out the same size every time. I've pasted below a few ini files that are relevant (I'm using Bethini ultra preset but with the shadow res turned down). I feel like it's the cache that's at fault, as 200MB seems way smaller than any of the reported cache sizes I've seen online (just seen one that says 1.8GB for example), but I can't be certain that it's not just failing to read the cache if anyone has any idea what's gone wrong, I'd love some assistance cheers skyrim.ini : skyrimprefs.ini : NGIO GrassControl.config.txt : GrassCacheHelperNG.ini :

hey! this did it! thanks!!!

yeah that's in there (priority 12 in my mod list) - I can't even start the game in 1.5 without that. the game runs fine but building the grass cache does not

Ive turned off every mod and it's still the same. so now it's just downgrade to 1.5, skse, address library, ESL support, engine fixes, dll loader, .net framework, USSEP and NGIO still instant CTD I've also found this log which shows that it is doing *something* [05 Jan 2024 21:53:09.366] Initializing framework version 15.

my 1.5 downgrade simply copies binkw64.dll, skyrimse.exe, skyrimselauncher.exe, steamapi64.dll, and data\interface.bsa from 1.5 (which I have downloaded in a separate folder) so maybe there's something I've done wrong here? I was struggling to get the 1.5 game to boot with all my mods and it turns out there's issues with USSEP and 1.5, plenty of posts say that the latest version of USSEP works if you have 1.5 binary but all the 1.6 data files, but I found this not to be the case and this would CTD, the only resolution I had for this was to use an earlier version of USSEP designed for 1.5. that solved that problem but then I had a couple of Northern Roads patches that reference the CC stuff which also crashed, I edited these in SSEEDit to remove the master references to the CC files and that seemed to sort this out. I was more worried about having accurate terrain for the grass cache than having fishing etc in this version of the game (I will return to 1.6 and full mods list once the grass cache is done, so I don't really care if this is a dirty fix) and Northern Roads edits the terrain and the patches for this are important otherwise there's glitches in the terrain layout. this seemed to solve the problems in that the game runs when I test it but maybe this is something to do with why it's crashing? I've since tried removing the CC files altogether - my reasoning being that if patches referencing these files would CTD then maybe all the CC stuff is incompatible with 1.5 so just get rid of it - but this didn't change anything

I'm running SkyrimSE 1.6 and I'm following the guide for generating grass LOD My standard setup is with 100 or so mods in MO2 and it's working well I've downgraded to 1.5 as per the guide and followed all the steps (1.6 data files still there except interface.bsa, all skse, address library, dll loader, ngio, etc all there, all mods that affect landscape etc are active, anything incompatible with 1.6 is reinstalled with 1.5 version etc etc) and the game works fine. I can start the game, load an early save with no mods in (just outside helgen) and it all works. I can run down to Riverwood and everything looks great when I go to build the grass cache, the game boots, and the message pops up instead of the usual start menu "this will build the grass cache press OK". I hit OK and then it's instant CTD I know it's expected to crash during this process, but this is *instant*. the game restarts like it's supposed to, and the exact same thing happens again. instant CTD. I went through this 10 or so times before deciding something really must be wrong with it I've got several crash logs, they all appear to have the same thing at the top (which suggests the same crash every time) but I can't really read these so maybe there's some more clues in there that someone else can make sense of. I'd love to figure out what's going on. I can't seem to attach files here so I've pasted them into the below blocks. I've also pasted the active mod list from MO2 in the first block (anything labelled 1.5 is unique to this profile, I'm using rootbuilder so my 1.5 downgrade and skse and all that stuff is all in here, so I can just change which mods are active to return to 1.6)

okay yes that's done it! thanks!

I'm attempting to follow the guide for grass LOD I'm running 1.6 with about 100 mods I've setup a separate 1.5 skyrim folder, and a new MO2 instance to control it, so I can build the grass cache SE1.5 runs fine, I've installed the base of skse, address library, engine fixes, ussep, dll loader, all specific to 1.5 and this is working fine from the skse loader - I can start the game no problem. I don't have any other mods installed yet, just these few, but I'll continue modding 1.5 to match my 1.6 game and testing it as I go, once it's all there and running correctly I'll build the grass cache from it. the problem is, following the guide, I can't get 1.5 to run where I have a problem is this line in the guide "Everything in the ..\Data directory MUST be from 1.6.xxx EXCEPT the Skyrim - Interface.bsa. Using the outdated ESMs will cause landscape to be incorrect" if I include skyrim.esm update.esm or any of the DLC esm from 1.6 into my 1.5 data folder, its CTD before I even reach the start menu. I get the bethesda logo for a bit and that's it the terrain mesh is in meshes though so will this work okay or am I screwed? there doesn't seem to be any way to get 1.5 skyrim to run with 1.6 skyrim.esm in the data folder, but other posts above suggest this is necessary as there's landscape edits in the skyrim.esm? is that definitely the case? checking again, it's all the bsa files that I've included, and the _resourcepack.esl, and it still boots. I can't include any esm files or its CTD. I've wrapped this lot up in a MO2 mod so its easy to hide/unhide files as needed. can't unhide any of the esm

the link to DepotDownloader in the first post is a hard link to v2.4.5 of the software, which is outdated and no longer works with Steam due to changes implemented by Valve the latest release v2.5.0 from June 2023 works correctly so anyone having problems needs to navigate to the releases page which has the latest version at the top, and download that version https://github.com/SteamRE/DepotDownloader/releases so ideally the link in the first post on this thread should be edited to go to the releases page as well, rather than sending people to an old version that does not work
