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"

.sln file missing when saving the project

Hi fantastic fellas Unreal Engine forum, I had a problem last night when I was trying to save my project. The engine suddenly crashed and when I tried to re-open it again it always crashed. When I opened the project folder I noticed that it didn't seem right. The .sln and some folders are missing. I noticed that the engine behaviour didn't seem alright when I import an FBX model. It was successful, but when I press the play button, the material of the FBX model of the character suddenly missing. Then it ended up crash when I try to save the project.

Here this is the log file I got :
