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"

how about swarm? did you check that?

avatar image HWDESIGN Jun 15 '16 at 09:16 PM

I'm not sure where to find those settings on Mac. I don't see any swarm agent like on windows. I didn't install unreal with github. I used the normal installer with Epic Launcher.

Does Mac or Linux for that matter even have Swarm? Staff said that swarm only runs on Windows (at end of 2014).

EDIT: Link to staff about swarm: https://answers.unrealengine.com/questions/27550/swarm-what-is-it-and-how-to-use-it.html

do you get the same error in a clean and blank project?

avatar image bitwiseben Jun 25 '16 at 02:01 PM

I do get the same error on a brand new project. I'm running UE4 on Linux.

avatar image Moazahmed123 Jun 16 '16 at 06:09 PM

actually my problem didn't 100% solve because when i click build the same message appear but it disappear and continue building but my shadows looks bad so am downloading 4.10 now cause it works fine with me.
