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"

I've been trying to create a project on UE4 for a while, but whenever I try to open a new, or old project, the editor crashes. I verified the engine and all that, but I can't find the problem, much less a solution to said problem. I'd be grateful for any help, thanks.

Product Version: UE 4.17

Turns out this issue is related https://answers.unrealengine.com/questions/677874/unreal-4170-crashes-on-project-load.html

Following these instructions, I was able to make the editor launch on my mac

  1. Disconnect external monitors (requirement for #2)

  2. Using GfxCardStatus, set my MBP to integrated graphics

  3. Launch Editor & Load Project

  4. Using GfxCardStatus, set my MBP to dynamic graphics

  5. Re-attach external monitors
