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"

Game Lagging Horribly After Building

I built the level with the tutorial found on the Unreal Engine youtube page: https://www.youtube.com/watch?v=I8WBF4AyAX4

It runs just fine in the editor, and when I hit play it runs at around 90 - 120 fps. However when I built the project and tried opening it it lagged horribly, it looked like less than 30 fps. Is there something I am missing or is my computer just not powerful enough to run it?

Strangely enough I think it was the hanging lights, removing them gave me a huge boost in FPS.

Did you ever find another solution to this? Surely just 1 light can't be causing such problem.

Like yourself, when running the game in the editor it's perfect. As soon as I package the game and run it, it struggles to run and is easily under 30fps too.

I'm also on the exact same tutorial :)
