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"

[Crash] Unable to Convert/Load 4.6 Project in 4.7 built from GitHub (4.7p5)

I just opened a 4.6 project in my 4.7 build and it crashes. I've tried opening straight from visual studio as it is a C++ project which seems to convert fine and compile the sources fine. I've tried asking for an in-place conversion on a fresh copy as well as launching the C++ project straight from visual studio. They both produce the same error at 66% of load. I'm building from the 4.7 GitHub branch as of 20150203 (last commit: 5bac1375be31053932c7b9123cc3bb94c70dd5e0). I've also tried running: UE4Editor.exe -run=resavepackages -maxver=214 just in case that was necessary, no difference.
