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"

How to render an actor to a texture

I've spend whole eternity trying to figure out how to do a simple thing - render an actor to a texture? Not capture with UCaptureSceneComponent2D, but render in it's own environment.

I've found the old code: https://answers.unrealengine.com/questions/367205/custom-gameviewportclient-render-off-screen.html but it works only under Editor. I've tried to investigate Kismet's DrawMaterialToRenderTarget with following straight simple code:

 UTexture2D* OffscreenRender::MakeTexture( const FString& name, UWorld* w )
     UStaticMesh* plane = LoadObject<UStaticMesh>(nullptr, TEXT("/Engine/BasicShapes/Plane"));
     UTextureRenderTarget2D* target = LoadObject<UTextureRenderTarget2D>(w, TEXT("/Game/Target"));
     UKismetRenderingLibrary::DrawMaterialToRenderTarget(w, target, plane->GetMaterial(0));
     return target->ConstructTexture2D(GWorld, name, EObjectFlags::RF_NoFlags, CTF_DeferCompression);

, but it leaves me with a blank texture. And I could not find any example of using it. Also I've found a number of similar question with no answers, and I believe this one will queue in the row.

Is there anything to do such a simple task?
