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"

Do you have debugging symbols installed? If you're not sure, open up the Epic Games Launcher and locate your version of the build. Click on the down arrow and select 'Options'. Once you're in that menu, make sure that Editor symbols for debugging is selected and then package in debug mode.

If you can package a blank template without any trouble too.

Hi Samantha,

Sorry but still new to UE4 ! How do I exactly package in debug mode ? I've tried packaging after installing debug tools but still no progress.

After installing debug then packing to Windows 64 = http://textuploader.com/d560g

Thanks !

If you go into Project Settings > Packaging and select 'Include Debug Files' - it'll include the debugging files that may be helpful. That way, your logs from the project should provide us additional information. Upload your new output logs as a .txt file, thanks!
