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"

I know a lot of peoples asked this before, but my error code is different (and I tried a lot of fixes who didnt worked for me). So I try to build a new C++ project and everytimes at 60% it crashed and says that :

Creating a blueprint project works. I tried to reinstall the version, reinstall visual studio, i have every SDK (windowd 10 and 8.1), the UE4 installer on VS, community edition. I verified the files of 4.20.

The error is "Illegal character in path", but i don't find any illegal characters! I just don't understand..

Thanks in advice!

Product Version: UE 4.20
