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"

Consistent crash on 4.14.1 mesh viewer


I'm getting some very annoying and consistent crashes when attempting to tweak any sort of value in the mesh viewer window on numerous meshes. At first I noticed it when attempting to apply materials to meshes that have multiple material IDs (2 or 3 at most) but now it appears that even tweaking other things such as lightmap size, or just playing around with checkboxes will result in an almost guaranteed crash which is really impeding my workflow :-( I'm up to date on my latest graphics card drivers GTX560. My stats are as follows:

Windows 7 Home Premium 64 bit Intel Core i7-3930k CPU @ 3.20GHz GeForce GTX 560 Ti 8GB RAM

I have never had consistent crash issues with any previous version of Unreal until now. This started with 4.14 and I was hopeful that 4.14.1 would fix my troubles but no such luck. Please let me know what I can do as I would prefer not to roll back to an older version of Unreal. Thank you!

Hi AlexanderAlza

Is your crash log showing something similar to this? - Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0006 - 'HUNG')

There are crash reports from some NVIDIA graphic cards in 4.14 and 4.14.1. There is a forum thread about the crash: https://forums.unrealengine.com/showthread.php?129394-to-developers-ue-4-14-crashes!-Error-0x887A0006-HUNG&p=638412&viewfull=1#post638412

There will be a QFE soon. Meanwhile you could try entering "r.gpustatsenabled 0" console command - that might help to workaround the crash.

Thanks for your response. Unfortunately the only thing my Crash Reporter says is:

"You do not have any debugging symbols required to display the callstack for this crash."

Thanks for your reply.

Without the callstack I can't say I'm 100% sure, but I still think your descriptions and your GPU shows you are experiencing the same crash discussed in the forum.

Please check the forum thread, and try the QFE when it'll be available. I hope it will fix your crash.

You absolutely nailed it, tried the "r.gpustatsenabled=0" fix and so far so good. I cannot thank you enough :-)

Happy to hear the workaround is working for you. Have a good day :)
