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"

What does bGPUSharedFlag do?

I'm reading over the API for UTextureRenderTarget2d and I found an interesting flag: bGPUSharedFlag. The documentation for this flag is pretty sparse. Does anyone know what it means by "GPU sharing?" If I am programmatically controlling access to a texture render target in such a way that I have guaranteed thread safety, could I enable this sharing to potentially increase performance when accessing my render target in code?

Product Version: UE 4.15

Good questions, especially as it gives insane performance gains when using ReadPixels on a TextureTarget Resource. Only drawback is HDR is not rendered.
