NOW THAT THAT'S OUT OF THE WAY

Hi everyone!

I have had a relatively stable Skyrim install but came across this huge issue. I'm trying to enter Blackreach from the usual dwemer ruin Alftand. I open the secret/locked passage, open the door, then the loading screen to Blackreach begins. However, it doesn't take long before my game crashes with this error message

 

Among my research, It is a corrupted mesh or texture, almost certainly caused by a mod conflict. I am not an especially smart modder but I have looked inside TES5Edit with ALL my mods and it loads without issues. I look up the FormID and there appears to be nothing wrong with it. The ID is not highlighted anyways, and if it is not flashing yellow or red then I don't know any better. I have verified game cache through Steam but of course that didn't resolve the issue. Using a fresh Skyrim.ini or SkyrimPrefs.ini file does not fix the issue either.

Uninstalling everything then reinstalling everything again as some have suggested in other threads on the web is way too drastic and time consuming for me to consider at this time. At the least, could anyone help me pin down suspicious mods that might be causing this conflict? Even if I narrow this down to 20-30 mods, that helps drastically. As you can tell, I don't have anything that specifically modifies Blackreach. I have explored many places in the savegame with these mods including expansive dwemer ruins and other places around Skyrim (no Dawnguard, Dragonborn, or new modded lands yet)

 

Conversely, if anyone has any other suggestions that lead me in a direction other than going on a witch hunt for conflicting mods, I would be glad to hear what you have to say as well.

 

Thank you in advance for any and all assistance!! Please ask for any more info that might help.

I think you're looking at the wrong formID there. Look at 487e8 instead. That should give you a list of mesh files that might be the problem. Since these formids are dealing with mountains, you can probably eliminate anything that doesn't alter mountains, landscapes, or LOD as a cause.

@DarkRudra Thank you for the help! You sent me to a good direction by pointing out I was looking at the wrong FormID. For anyone who might look at this in the future, I'll explain what worked for me.

That 2nd formID that Rudra provided was what I needed. It would probably be safe to investigate both IDs just in case, but the 2nd one was my culprit. The only thing modifying this mesh (no LODs, thank god) was Enhanced Lights and FX installed through NMM. As popular as the mod is, clearly there was something special about my Skyrim install that made this happen. Maybe a bad download, bad install, who knows. There are three important things I did in this process:

 

1) What fixed my problem in the END was completely uninstalling ELFX then reinstalling it (dont forget to run LOOT or whatever you use again).

2) I rebuilded my Bashed Patch. Try it, it could work!

3) I noticed red highlighted items listed nearby my "culprit" mesh. In my case, "Regional Snow and Ice" was causing the red conflict warning relevant to the Blackreach area. I've uninstalled it for the moment but will reinstall it soon, considering this did not fix my error. However, any red highlighted FormIDs relevant to the room/cell you're trying to load in-game is worth investigating.

 

If anyone else is experiencing a similar issue (in Blackreach or otherwise), chances are your issue will not be coming from ELFX or my snow & ice mod. Whatever mods, active or inactive, TES5Edit claims is altering the mesh in question, you should completely uninstall any and all mods it references. Load into your game, and see if the issue is fixed. Reinstall those mods one-by-one, and ideally your game will work again with all your mods in-tact. If the issue comes back, then you know the specific mod causing the issue, and you can decide what to do with it then.

If I have anymore troubles in the recent future pertaining to this issue, I will update the thread. Otherwise, everything is fine and dandy! Have a good day everyone :)
