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"

glreadpixels equivalent (colour and DEPTH)

I have seen code relating to Viewport->ReadPixels to capture colour bytes.

But I also need to capture the corresponding depth values (of the whole final scene) for further processing outside of the shader system.

So I need the UE4 equivalent of a glreadpixels call.

I don't mind if the depthbuffer resolution is 24bit (as I believe that is what most cards default too) but if there is a 32 bit mode than that's a bonus.

Does anyone know how to access the depth buffer in system memory?
