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"

Screenshot glow effect problem

Hi everyone. I have FloatRGB texture where some pixels have values more than 1. If it would be emissive color in material then I got glow effect like this:

To get glow effect I try to render texture with DefaultLit material in canvas by next material and code:

alt text

     material->SetTextureParameterValue(TEXT("texture"), m_screenshot.result);
     FCanvasTileItem tile(
       FVector2D(0.0f, 0.0f),
       FVector2D(1.0f, 1.0f));

 finalTexture->InitCustomFormat(SCREENSHOT_SIZE, SCREENSHOT_SIZE, EPixelFormat::PF_B8G8R8A8, false);

     FCanvas* canvas=new FCanvas(finalTexture->GameThread_GetRenderTargetResource(), NULL, 0.0f, 0.0f, 0.0f, GMaxRHIFeatureLevel);
     canvas->DrawItem(tile, FVector2D::ZeroVector);
     delete canvas;

But finalTexture doesn't have glow effect:

What should I do?
