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"

Unreal engine crashing after a few minutes

I've got an assignment for a game design class due in a week, and whenever I try to work on it in unreal after about 5 or 10 minutes the program freezes and crashes. There doesn't seem to be a lot of rhyme or reason to what causes the crashes from what I've seen, but it happened this time when I was editing a landscape.[Here's the crash log (I think?)][1]

I'm using an HP omen laptop running windows 10, with about 8 gigs of memory, an intel core i7 processor, and a built in GeForce GTX 1050 graphics card. i'm not sure what else would be relevant to this but if there's anything else that would elp please let me know.

Your GPU driver crashes

  at D:\Build\++UE4\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Viewport.cpp:304 
 [2018.12.04-21.37.28:178][640]LogD3D11RHI: [Aftermath] GDynamicRHI=00000246E27E4100, GDX11NVAfterMathEnabled=0, Result=0xFFFFFFFF, bDeviceActive=0

You might try to updating it, but considering you got laptop with 2 GPUs and it crash on speciifc amount of time this might be related to power saving features of your laptop, system might trying to go back to Intel GPU after a while and it crashes UE4 on the way. So try updating other laptop drivers and check power management settings, you might try google how to keep your nvidia GPU on all the time on that laptop
