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"

Hey KalliAbi,

Let's start by resetting the Swarm Cache and make sure we haven't got bad data stored. Ensure that your editor and Launcher are closed and then go to C:\Users[User Name]\AppData\Local\UnrealEngine\4.7\Saved\Swarm\SwarmCache\ and delete all the files in this folder. Re-open your editor and project and attempt to build lighting again.

If this does not work for you, please upload your new logs so that we can further assist you, thank you. :)

Hey KalliAbi,

I understand you were not able to find Swarm. Have you been able to build on any other template? Also, have you tried 4.8.0 Preview 4 to build your project? I would consider creating a copy of your project, do not just convert it to 4.8, please.

Looking forward to hearing back from you. :)

Could I please have your full crash logs as a .txt file? I'm beginning to believe that it's your RAM that's causing the issue. We highly suggest 8 GB of RAM or more.

Hey KalliAbi,

I have not heard from you in quite a few days and for this reason, I must mark this question as resolved. However, if you're still experiencing trouble with building in UE4, please do not hesitate to reply back.

Thank you and have a great day!

Hey KalliAbi,

I'm so happy to hear that reinstalling has fixed the issue you were originally having. Since you're having trouble with exporting your project for an Android device, I would highly suggest you post a new question on AnswerHub. Please include all of the information that you possibly can, and any logs that may be helpful, especially since you're receiving a black screen. Include the model of the device you're working on too in that post.

Thank you. :)
