Re: Stumped on what CC/Mod is causing game to crash?

I tried, still crashing. At this point in time, the game crashes a few seconds into gameplay. Maybe 5 seconds after live mode begins, it crashes immediately. Unsure where to go from here, I've just about tried everything. 

Oh I think we had a misunderstanding. 

With mods / cc removed its fine.

With mods only, it's fine. 

With CAS cc, it's fine.

With build/buy cc it crashes, but I can't pinpoint what it is. It seems when I do the 50/50 method to try to nail it down, the game switches up what causes a crash. For example, if one folder is deemed fine 10 times, the 11th it won't be and will suddenly cause a crash. So it's been impossible for me to rule out what the issue is, making me think maybe the save file is corrupted or something?

In addition to what @luthienrising suggests, you might want to take a look at your build/buy CC in Sims4Studio (S4S) to see if you can spot the problem file(s) that way.  You might be surprised at what you find.  I know I was when I did it for pretty much the same problem a couple of years ago.  I found a slew of problem files that I ended up removing.  And my game runs a lot better than it did before and loads faster as well.

You might find a few things you have aren't even showing in the game catalog.  I did.  The objects were broken from day one and I never realized it. 

Take a close look at anything that was created to add recolors to a game object.  Make sure you look at all the recolors to make sure they actually show too.  But tbh, a standalone item is more likely the problem.  If you have things like default replacements that add slots, those won't show in S4S but could be broken.  Test those in a throwaway save to see if they actually work.  And that goes for anything you have that doesn't give you a visual in S4S. Some broken items simply won't show up at all there. If you don't have all game packs, it could be something where the creator used an item as a base object from a pack you don't have.  As such, the item will probably not show up in the catalog at all or show up distorted, give you a thumbnail that is messed up or just disappear when you try to place it on a lot.  Walls and floors typically don't give problems but again, just make sure they work.

One thing you might want to consider is reducing your build/buy CC.  If you're like me, I tend to use the same items over and over again and there were lots of things in my mods folder I used once or not ever.  So, removing things like that has a lot of benefits - less to go through when you have a problem, and the game loads faster and runs smoother has been my experience after cleaning out my CC, both build/buy and CAS.   

Another thing you can try is reducing your graphics setting down a level.  That will decrease the detail of distant objects you are able to see in the game from a lot.  You'll probably need to experiment a bit to find settings that you like.  One more thing you can try is trying a custom GraphicsRules.sgr file.  There are many out there so try a few and see if you can find one that stops the crashing but is to your liking.  

Hope this helps.

Thank you, truthfully, at this point I do have a lot of build buy cc, and I started trying to divide my files and rule out what is causing that crash, but it'll take me a few days.. so I'm still in that process. It's so incredibly tedious. 

Also, I do have Sims4Studio, but may I ask how do I use it to find broken cc? I didn't know we could do it on that.

And thank you, I'll def take a look and see.

May I also ask you for a bit more info on what a GraphicsRule.sgr file is? Ive never heard of that before. 

A little update: Currently still in the process of ruling out all folders / files that are causing a crash.. its quite a few folders truthfully.

Is there a possibility that the save file itself is corrupt? Maybe, or maybe not from bad CC? 

I went back to backup of my current save file, and playing it from when before it was crashing.. it seems fine. Mind you it did crash but not immediately we're talking like maybe 3-4 hrs into gameplay which was the norm for me prior.

I'm worried it'll start crashing sooner, and sooner again.. so I guess I'll keep an eye on it.

Just trying to rule out what it could possibility be.  

Also, about downloaded recent CC.. I've only recently downloaded new CAS CC, and all CAS is completely fine in the game, only build buy cc causes a crash. 

It's possible for a save to be corrupted, but if it's not crashing with CC and is crashing with some other CC, it seems more likely to be the CC. You can do testing on a new save, though.

Crashing even a few hours into gameplay is also not normal, though.

Okay, for the build CC, you can test in a couple of methods: by creator or by function. If you already organize your CC by creator, that's probably the easiest method. If you don't have it organized, though, you could either organize by creator (with an "everyone else" for creators who don't put their name in the file name) or by function. If you organize by function, I'd suggest first testing batches of appliances, activity objects, doors, fences and gates, and seating.

You might also have duplicates, which while not likely to cause crashing, isn't going to help. MC Command Center and Better Exceptions both have ways to help you identify and get rid of duplicates.

Sims 4 Studio does have some batch functions that you might want to run on CC in case you got older content that was never updated for particular patches.

How to use S4S to find broken CC is pretty simple.  Just click on the My CC button on the right.  That opens a new window showing everything in your mods folder.  If you keep things in subfolders, for instance, that's what you see, and you'll have to click on the subfolder to see what's inside.  Then just click on an object file and new window opens with a visual of the object.  You can rotate the object so you can look at it from all sides.  On the right side there is a list showing the category and other details.  If you've used S4S before, it's pretty much the same for objects as it is for CAS items more or less.  I use it to check all my CC just to make sure it's not obviously broken before I put it in my game.  It won't catch everything, but it does catch a good many things.

What you are looking for is to make sure the object will show up visually.  Many broken items won't.  They either won't show up at all or just not look right.  It's usually pretty obvious though.  You need to be aware that default replacement objects won't show up visually even if they are ok, so you have to check the items that don't give you a visual in S4S in the game.  I always use a throw away save for testing things like that.  Anything that doesn't show up in S4S and doesn't show up in game is broken and should be removed.  

Sometimes objects may have weird looking appearances, like there is a spike that seems to go away from the object.  That indicates a mesh problem, and the item should be removed.  Those objects might look fine in game if they show at all but usually, they don't show up in the catalog and are broken.  You're also looking to make sure the recolors work, so you should go through all the swatches on the upper right by clicking on each one.  Sometimes you'll find one that does weird things. If you see anything that doesn't look right, then you can isolate it and test in game to make sure nothing is off.  

Going through each item individually will take loads of time if you have a lot of CC.  I suggest that you isolate the items as best as you can first and look at those in S4S first before trying to go through everything you have.  But, at some point, you probably ought to look at everything you have.  

A GraphicsRules.sgr file is the game file that dictates how the game appears on screen.  It includes info like your graphics card, some system info, graphics settings etc.  The game won't run without it.  It is created when the game is installed.  Normally, the file is in the game files but if your graphics performance is not what you'd like the devs gave us a way to create one of our own and that one is kept in the ConfigOverride folder in the user folder (The Sims 4) and overrides the game file.  But as I understand it from @Bluebellflora your system should run just fine without a custom one.  I only mentioned it as a last-ditch effort if you can't find another source for your crashing.  

As for the save being corrupt, that's always a possibility but I agree with @luthienrising probably not in your case.  I think the cause is broken CC.  Probably build/buy based on what you've said.  But it could be CAS CC too.  Maybe something that you only put on one or two sims or if you have items set for random use, the game could have used it on an NPC or two and you get a crash whenever those sims enter the zone you're playing in.  So if you go through all your build/buy CC and don't find the problem file, then you should go through your CAS CC.  

Hope this helps.
