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"

UE4 editor crashes with a fatal error D3D11Util.cpp] [Line: 181] Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0020 - 'INTERNAL_ERROR')

link text

The UE4 editor crashes every few minutes, first noticed when I tried to run a C++ project with some changes I included. But after that I have tried a normal BP project without any changes, it still dies in few minutes.

I tried both the version 4.17 and 4.15, same issue "D3D device being lost" comes and crashes my UE$ with a hung window if I don't report it. Kindly request any one to help. I am desperate to get this working

System Details: Windows 10 16Gb ram AMD Radeon
Intel graphics 620 HDD 1tb

Thanks for your time,

Best Regards, Raj

Product Version: UE 4.15

The issue was with the AMD Radeon driver i recently upgraded, once i downgraded it everything went fine. The version i have is the one that was released on 03- Sep-2016. The version numbers are different on the site and different in my system. So its better to go with the date.
