Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Packaged Game Intermittently Crashing when loading level

Hello,

I've been having this problem since 4.17 where my packaged game intermittently crashes because of failing "ensure"s but I have no idea how to debug this and if this is bug with the engine:

Looks like you are running a for loop on an array and changing the size of the array within the loop itself. That causes an error because the for loop doesn't know anymore how many elements it has to loop over.

Hmm that's interesting, since this occurs on level load, it might be from the way I programmed my level streaming, but I specifically targeted that problem by iterating over one array and adding loaded or unloaded levels to another array and then comparing the two to see which levels were loaded or unloaded so that I wasn't performing the operation more than once on one level.

avatar image ujrkingdom Feb 07 '18 at 05:56 AM

So I've tracked down the problem to be related with the Async Loading Thread Enabled Option under Package-Streaming, problem is is that if I disable it, the physics and collisions in my packaged game breaks. And to be extra sure I checked all the foreach loops and made sure none of the TArrays were being modified inside and all of them came out clean.

It doesn't seem to be coming from any of my code

This seems to be generated by TextureStreaming. A quick search showed that others have had similar issues. Maybe this one can help:

I enabled never stream for all my textures, repackaged and still didn't fix the issue

avatar image vr_marco Feb 07 '18 at 02:32 PM

Ok, definitely we need to go more in depth on this error. Question: did you compile the engine yourself or is this a standard release? Another question: did you install the the Debug Symbols for it? Finally: Is there any additional information in the .log which could hint to something being wrong with your Textures?

avatar image ujrkingdom Feb 07 '18 at 02:52 PM

Yes I compiled the engine myself, I think I installed the debug symbols as I am able to debug the editor and the packaged game although as far as the packaged game is concerned I can't set break points in the engine code. And for the log there's multiple warnings that are there for one of my widget classes where it says "using slow createwidget path because this class could not be templated" and since I have both an amd and Nvidia card installed in my system I get at the very beginning of the log multiple instances of "GetVideoDriverDetailsInvalid PrimaryIsNotTheChoosenAdapter" and the ensure failed error also only occurs in the middle of level streaming.

avatar image vr_marco Feb 07 '18 at 02:57 PM

Ok, did you try already to:

  1. Delete the Intermediate, Saved and Build folders, then reopen and play your project

  2. Migrate your levels to a brand new project and see if that solves the issue

Maybe it is just a problem of corrupted working files which result in a TextureStreaming error.

avatar image vr_marco Feb 07 '18 at 03:25 PM

And another thing that puzzles me. If you built the engine yourself from source code and you are using a DEBUG build, you should be able to place breakpoints in the engine source code. You may want to double check that.

avatar image ujrkingdom Feb 07 '18 at 05:40 PM

Okay so I migrated my assets to a new project and now I am able to disable async loading thread enabled without breaking the physics and now the error disappears. I guess for now I'll just assume that the error is coming from that option and that's its broken in 4.18, I'll test it out with 4.19 when it is released and see if it resolved. As for the debugging I'm not sure why but using either debug editor or debug game profiles in visual studio and hooking it with my packaged game doesn't allow me to set breakpoints in engine code, and it might the debug files that the game puts in the directory are only for the game code and not engine code.

I solved an issue similar to this and hope this message helps someone in the future. I had crashes only in packaged builds (never editor) with the following log error:

 Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address ...

and

 Warning: CreateProc failed: The system cannot find the file specified. 

Experienced devs told me 99% of the time it's a null pointer error, meaning you are referencing something in your c++ or blueprints which can't be referenced (usually because it doesn't exist, for example it hasn't yet been instantiated). This was true in my case.

The way to solve this issue:

1) Look in your log folder. ([yourprojectname]>Saved>Crashes). Look for the FATAL ERROR near the end and look underneath that for the callstack hint which will steer you where your problem is. In my case, it looked like this:

 [2018.07.30-19.19.53:720][ 0]LogWindows: Error: Fatal error!
 [2018.07.30-19.19.53:720][ 0]LogWindows: Error: 
 [2018.07.30-19.19.53:720][ 0]LogWindows: Error: Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0xfad70000
 [2018.07.30-19.19.53:720][ 0]LogWindows: Error: 
 [2018.07.30-19.19.53:720][ 0]LogWindows: Error: [Callstack] 0x00007ff716532680 
 AAADragonFresh.exe!AlgoImpl::IntroSortInternal<TBitArray<FDefaultBitArrayAllocator>,FIdentityFunctor,TDereferenceWrapper<TBitArray<FDefaultBitArrayAllocator>,TGreater<TBitArray<FDefaultBitArrayAllocator> > > >() []
 [2018.07.30-19.19.53:720][ 0]LogWindows: Error: [Callstack] 0x00007ff7165ca3b9 AAADragonFresh.exe!FSkeletalMeshLODRenderData::InitResources() []

Notice the last message in mine. It contains the words "skeletalMesh", "sort", "TBitArray". In my case, the null pointer was a reference to a skeletal mesh inside of a switch.

2) Go into a blueprint you think the log could be referring to and disconnect the tick, begin play, and constructor wires, effectively deactivating the blueprint, and then package and run. If it stops crashing, you've found the blueprint with your toxic reference. You're zeroing in!

3) Reconnect your wires and disconnect only the part you think is responsible until the packaged build stops crashing. Find your bad reference, and then figure out why it's a bad reference. Have you instantiated it yet? (You can put in printstrings, or you can put in breakpoints and step through your blueprints to find out). In my case, it was something stranger which really threw me off: I had imported the mesh from Blender with the skeleton turned to invisible. This was enough to throw off ue4, but only when ue4 was trying to load it (hence why only the crashes in packaged builds).

The first time debugging something like this is hell, but have faith that you can and will get through it, and once you do, you'll have tremendous confidence moving forward!

Thanks for the post on this, as a blueprint programmer (building in source) it helps my mindset to understand the concept. Oddly I went through a PC upgrade and my project was started on Win7 and now is crashing on several unreal engine versions (4.19, 4.19.2 and 4.20.2) on Win10.

Still working on the issue but I've narrowed it down atleast!
