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"

Fatal Error on startup

Whenever I hover over any icon, I'm hit with this error and UE4 crashes.If I'm quick enough I am able to do the action by the icon by clicking the icon real fast and then moving my mouse away from it.I tried googling but none of the responses had a proper workaround or a solution(The real time thumbnails didn't work too).It crashes only when I hover an object though.If I don't place my mouse anywhere near those objects UE4 works just fine.Also, this happens randomly.The crash occurs 9 out of 10 times. Here's the entire detail:

I am able to interact with the icons if I do it quick as in click the icon quickly and move my mouse away real quick.But the crash occurs after a few minutes even if I keep it still.

In this case I would recommend you open your epic launcher and verify the install is okay, or uninstall the engine and reinstall it again. does your computer have a decent GPU?

GPU is R9M375X and yeah I am uninstalling th engine and trying to reinstall it again

avatar image jimd667 Aug 02 '17 at 05:04 PM

does it work now? if re-installing was the answer please mark it as solved so others can debug their systems.

Thanks

Yeah uninstalling seems to have done it for now

Uninstalling the engine and making a fresh install of the newest updated version of the engine worked for me.If the same problem occurs for you should verify the engine install first and then install the latest version.
