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"

Does Scene Capture support opacity in Feature Level ES2 ?

Hi, there:

Scene Capture is improved is 4.13 and new capture sources are supported, among witch "Scene Color (HDR)" i care most as it writes opacity to alpha channel with which i can alpha blend with some other things.

I select "Scene Color (HDR)", it works fine, inverted opacity is successfully written to alpha channel of the render target( feature level SM5). But when i switch to feature level es2, alpha channel is not written with opacity. As es2 uses forward renderer rather than deferred renderer, i wonder if new features of Scene Capture are only supported in SM4 and above?

Product Version: UE 4.13
