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"

Editor crashing while adding post process settings variable


While working in UE blueprint editor a power went down. So I switched a power plan on my notebook to "Balanced" and continued doing job. After power came back the problem occurred: 1) Added "Post Process Settings" type variable node to blueprint and tried to set it's value. 2) After closing blueprint and UE editor, opening blueprint again and trying to do anything with this variable node or nodes connected to it crash appears, sometimes with Windows 7 notification (don't remember exactly): "This application tried to do something incompatible... Windows 7 Aero scheme will be switched to Windows 7 Basic..."

This is crash log:

Hi I am using 4.8.3 because I started my project in that engine, I would prefer not to change engine in the middle of my project. Is there a way to fix this, or if I just leave it there and not touch it, would it become heavy for the game or something?
