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"

That's not good, can I ask for the project logs from ~/Library/Logs/Unreal Engine/?

That will include more details of the failure that we can use to diagnose this problem.

There's an assert firing that one of the objects isn't valid so with a bit of luck that won't be too hard to track down next week.

Apologies that you've hit all these issues, but thanks for filing them all so clearly as that really helps. Knowing what is broken makes fixing & improving the Mac version a lot easier.

Being a full-time self-employed Mac developer myself, I completely understand. :)

There are a couple more — one of them is driving me insane every 3 minutes or so, but I haven't figured out how to replicate it consistently and it doesn't cause a crash so I have no log to send along…

Having the same problem here! Hopefully will be a fix soon- for the time being you can create the static meshes in 4.3, and re import!
