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 4.17.2 Crashing (Mac OS X)

Unreal Version: 4.17 Xcode Version: 9.0 (9A235) macOS Version: 10.12.6

Spec: MacBook Pro (Retina, 15-inch, Mid 2015) 2.5 GHz Intel Core i7 16 GB 1600 MHz DDR3 Intel Iris Pro 1536 MB

UE Hard Crashes on the following actions in the blueprint editor:

1) Trying to save 2) Press Control 3) Press Command 4) Press Alt

Rendering it pretty much unusable.

It crashes with the following output in the crash reporter:

Any advice would be greatly appreciated.

I read in some places that there are some case sensitivity issues in some places - I am wondering whether that has something to do with it? Also the fact that Unreal complains about my version of xcode (incorrectly - stating it is too older while in fact it is newer than the one it recommends) also has me concerned (App Store version of Xcode has now moved onto 9 and is no longer beta so it seems like a fairly major issue if this is the case).

Hi LiamNeko,

Sorry for not getting back to you sooner on this post. Are you still having trouble with this? I tried to reproduce the crash that you described, but the none of the four actions that you mentioned produced a crash for me in 4.17.2.
