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"

Shader compilation abnormally slow

Recently, I started to have very long waits for shader compilation. The material graphs don't update very quickly either. This was not previously a problem. I can resolve it by manually changing ShaderCompileWorker from low priority, but have to do this every time shaders start to compile. It will sometimes compile more quickly if I save a material while waiting. The program will sit with the same number of shaders to be compiled for minutes at a time, which was never an issue before.

I have noted this with both 4.9 and 4.10.

Product Version: UE 4.10
