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 Crashes Randomly

I am using a MSI GV62-8RD notebook and with Geforce Game Ready Drivers 417.71 running on windows 10. Randomly I'll be working and then the engine will crash, I did some digging and essentially the GPU drivers try to restart and fail but I don't have the exact error log, I'll update the post when it crashes next. It has no rhyme or reason, it'll just crash randomly for no reason and the only solution I've found is to reinstall the drivers and wait for it to crash again in a few days. Is the issue with my graphics card or is that an issue with the drivers I'm using?

Product Version: UE 4.21

You put a lot of details, but not the good ones.

Does it crash on every project ?

Does it crash on save or on auto-save ?

Did you use the repair tool ?

Did you install a new software used by UE (like Visual Studio), or uninstall a software which could be used by UE ?

Yes, it crashes on every project, it will do it randomly, not when I'm doing anything specific. I have not used the repair tool, I'm not sure what you mean by that, and no I am using the latest UE with blueprints and no other programs

If it is on every project (and then even new ones), it means that the problem comes from UE4 or from your PC.

I advise you to clean up your PC with Glary Utilities. Try to reinstall UE4.

If it still happens, try to take a screenshot and post it (it will be easier to help), and try to force the crash (it can seem random but maybe it's something over time like memory saturation, or undo history).

I mean this for the repair tool. (By the way I found the picture on this website, maybe it can help you.) alt text

I figured out it's an issue with my GPU, I've been having issues with other graphic based programs other than just UE4 and the error I get is an issue with the GPU and the drivers for it, not the engine itself. Thanks for trying to help
