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"

Create SRV From MediaTexture

I am using a custom compute shader which reads from a SRV. Currently I load a still image via UTexture2D and get the FTexture2DRHIRef via

 static_cast<FTexture2DResource*>(InputRgbaTexture->Resource)->GetTexture2DRHI();

from which I create a SRV using RHICreateShaderResourceView(..).

Now I want to do the same with a Media Texture, but there doesn't seem to be a simple way to do so, if the textures sink mode is Buffered.

Using AcquireTextureSinkBuffer() to get the raw data and copying it to another Texture seems weird.

Is there a simpler way?

Perhaps you could try something like this:

 FRHITexture2D* RHITexture2D = MyTexture->Resource->TextureRHI->GetTexture2D();


Each one of the dereferenced fields may be nullptr, so you have to check accordingly.

Your downcast of the resource to FTexture2DResource is never going to work, because FMediaTextureResource inherits from FTextureResource.

Ah thanks, worked perfectly! I missed the public TextureRHI of FTexture.
