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"

UE4 shaders/materials broken when starting in steam

Hi, The entire Scene is black, except the skybox, but only when I run the game via steam. Running without steam works fine. Is there anything in the logs I can look for? It says "Failed to load Shared Shader Library" even if I run it without steam, so that's not the issue I assume.

Product Version: UE 4.21

I was able to figure out something more: I've 2 levels, let's call them A and B. A is using a post-processing volume, B is not. A is completely black as I mentioned, however, in B there's colours, but shadows are missing. Only when I run it via steam, everything works as expected without.

apparently it was the "experimental" opengl/vulkan support for windows. switching to d3d solved it.
