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"

It keeps lagging EPICALLY when I load a project...

It's crashed my Mac twice now. No one can say it's the computer, this thing is brand new, desktop, i7, etc. When I start, it's fine, great even, but if I save it, and close out, then try to load the project, everything goes to hell, and it's extremely laggy, then the whole computer crashes. How do I fix this? It does the same if I package the game and try to play it. Completely unresponsive. Also, it says something about fixing the lighting, and 18 unbuilt objects, what's that mean? I deleted the lighting because I didn't want it, why would I rebuild it?

It probably is the computer. I'm not saying the desktop has issues, macs just aren't strong enough for UE4 development. It's not at all the platform you want to use for anything game related.
