Fallout 4 Modding Limit

[Ank]

Hello, I wanna ask about mod limit in Fallout 4.
Recently I have hit about 295 plugins, with 48 ESM/ESP and 247 ESL, which should be fine because ESL doesn't count to 254 plugin limit right?

But I can't actually add anymore mods after my 295 plugins, if I try, it will crash shortly after the main menu load. It doesn't matter what mods I add, weapons, quest, settlement, power armor, hair, even a simple skin... they will crash my game after the main menu load.

I think I probably hit a keyword limit, which is somewhere around 64.000 right? Or am I wrong?
I checked all keyword from my installed mods with xEdit filter and it shows around 7.000 or so... which I should still have plenty of room...

Anyone has any ideas?

Which mod manager are you using?

Mod Organizer 2... forgot to mention that...

I don't know exactly whats going on but I have a couple of thoughts. In theory the esl/ESL limit is 4096 plugins. However with extensive testing, done by people who know what they are doing, with full esl files (before the RefID increase allowed in FO4) the limit was closer to 300-600. Now those are new records, not overwrites. Overwrites dont count. So thats a possibility, however I doubt you could find 300 full esl/ESL plugins on Nexus right now. Another possibility is the ref handle limit, but that is unlikely, you don't have enough mods.

A big question is exactly when the game crashes. The game crashing at different points of loading can give clues as to whats going on. Can you get the game fully loaded? Are you making sure that your not adding any mods that add things like holotapes before you exit the vault? I don't know where your at, so thats why I'm asking.

I have 247 ESL including the one from the creation club yes, as for when my game crashes, its in the main menu. I can play the game just fine with 295 plugins without crashes and issues. But if I try to add any more mods, doesn't matter if they are in ESP or ESL, or what kind of mods they are, it will crash right after the main menu load. I feel like I hit some limit there.

Maybe I hit the ESL records limit? But it still crash with ESP. All I know is 295 plugins and I can play the game just fine all day. Anymore than that, I can't play at all. I just want to know if there are some more limitation in Fallout 4 engine I don't know about.

In xEdit, load your whole load order and then run the Count_loaded_refs_in_load_order script and paste the results here. That will let us know if your hitting the ref handle limit. Its doubtful, but it will rule that out.

Also, post your load order from LOOT.

Here it is. From what I read the Ref Handle limit is 2^20 or 1.048.576. I guess that rule that out.
As for my Load Order, I don't exactly use LOOT, I kinda made my own load order here. Not sure how that would help since with 295 plugins I can play the game just fine. I just can't add more mods, whatever they are.

[Chef]

A couple of questions.

Did you change the names of those plugins yourself?

Where did Precombined world come from?

The red handle limit for FO4 is 2^21, Skyrim is 2^20.

[Ank]

Yes I change them myself and tweak them to my liking too.
The precombined comes from this: https://www.nexusmods.com/fallout4/mods/45360
Most of these ESP are flagged as ESL too.

[Chef]

The only problem with changing them (I think, there may be other issues) is if they are a master to any other plugin. That would cause a crash on load, which you may be experiencing.

I haven't gotten around to looking at that FPS fix mod yet. There is a chance that it could be reverting worldspace changes by other mods. That may be a thing too.

I'm also going to ask a couple of friends if they will take a glance.

[Ank]

I know about dependent master, that's not the problem since I can play 295 plugins just fine, the problem is I can't add more.

Well, that FPS fix mod is recommended by some, says its the next Boston FPS fix. It probably is the problem, the mod itself is around 7-8GB in size. I'll run a test without it. Thanks.

[Chef]

That sounds compressed. Last time I talked to someone remaking the precombs they were sitting around 11gb.

I know that your symptom is that anytime you add one more mod you have an issue. But I'm trying to go through the easy stuff first. I find its always best to eliminate the easy, common stuff first. And, it's always hard to judge the knowledge of someone without seeing them post for awhile. Ill see if I can think of anything else.

Good grief. I'm actually a bit shocked the game will load a ba2 that large. I knew there was no theoretical limit for FO4, but I havn't seen anyone make one that large yet. 8gb.

[Ank]

Well, thanks for your help and input anyway, I'm gonna stick with 295 plugins for now and run some more test later on.

[Chef]

If you wouldn't mind updating here if you find a solution, I would be interested in it.

Hey, just to be more clear, the reference we were talking about is world object right? Because if I use filter to see only REFR - which is placed object in the worldspace... this is the result...

[00:27] Done: Applying Filter, [Pass 1] Processed Records: 2082842, [Pass 2] Processed Records: 1935976, Remaining unfiltered nodes: 1861688, Elapsed Time: 00:27

And if my calculator is right, 2^21 is 2.097.152. The first filter pass is 2.082.842. If that is what I think it is... then I am hitting the REFR limit... although we don't know how much is persistent and how is temporary...
