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"

Can't build lighting on Mac - pc works fine

We're having a problem building lighting. This only happens on a Mac machine - not on PC. We're using a very slightly modified version of the 4.6.1 engine. The firewall is not enabled, and static lighting is enabled.

When I click "build", it says "building lighting: 0%" and then a box comes up saying that building lighting failed. There's not a lot in the log window to go on - see below. Any suggestions would be appreciated!

Hello jcoombs,

Sorry to hear you are experiencing this issue. Would you mind providing me with your system specs/information?

When you say slightly modified version of the engine 4.6.1, I am assuming you have added your own code?

Have you attempted your Lightmass build without this code addition?

Thank you,

Andrew Hurley

Hi Andrew,

it turns out this was a result of a mismatched debug/development editor & unreallightmass. I rebuilt unreallightmass so that it was the same configuration as the editor and things worked fine.

Disable Firewall, DNSCrypt and other programs that can modify network. Worked for me.

can someone explain how to do this to me? I have the same problem, which is a different problem than I had BEFORE today's update. See previous problem here: https://answers.unrealengine.com/questions/315999/lighting-wont-build-ut-map-editor-argh.html
