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"

Nvidia's VXGI2-4.21 + PixelStreaming triggers "Failed to register input back buffer"

I'm trying to use nvidia's vxgi2-4.21 with pixel streaming and get this exception. alt text

Any thoughts on what's going on there and if it's at all doable would be much appreciated. It's in NvVideoEncoder.cpp

Product Version: UE 4.21

It's the dx 12.

I have the same error with 4.21 vxgi. Port all the project in 4.22 preview. Work very well in local, but i notice that there isnt ray tracing. So i add the argument -dx12 to start the exe like you need to use raytracing in the editor end get same error.

Sorry for my english.
