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"

UE 4.22 Ray Tracing Glass Material Problem


I'm testing out the new ray tracing feature and I'm wondering what parameter I need to tweak to be able to trace through glass materials.

alt text As you can see in this screenshot, the light does not appear in reflections. The window is one mesh, set up with Material ID's for the frame and glass etc.

alt text For this window though, I separated the frame and the glass and it works well. I'm using the same glass material on both windows, but somehow they behave different. Is this a bug or am I missing something?
