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"

Write to multiple render targets in UE4

I want to write a .usf shader that outputs to color, depth and normals but I can't figure out the documentation.

It seems I have to use a SetRenderTarget() which takes a RHICommandListImmediate and a RenderTarget texture. But I want the render target to be 3 gbuffers (not a texture2d picture) and generate a DrawPrimitiveUP() fullscreen screenspace quad in the world. How do I do this?

I also saw something called GSceneRenderTargets somewhere. Where can I find documentation and usage examples for this stuff?

Side note: Where can I define at which render stage do I insert my shader? For example I want to inject it before the deferred lighting stage.

Product Version: UE 4.13
