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 4.16.3 crash when cursor interacts with viewport

This is my project for work. Example projects I've downloaded from UE work as expected. When I open this project though (which does work for the rest of the team, although I think all of them are on windows), it crashes as soon as the cursor enters or interacts with the viewport. I can't tell much more about the crash, other than from reading the log (which I'm posting the relevant part of, along with the screenshot showing my macbook specs below) is that it seems that possibly the metal material is crashing the graphics card?

Try upgrade the driver of your graphics card.

I have a macbook pro, graphics card drivers are included with OS X updates. I'm running sierra, with all updates, and I really don't want to update my os to El Capitan as to what other issues that may cause.
