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"

Access violation while trying to access ID3D11Texture2D

Hey,

I plan to use cuda in my project. To do this, I already got the ID3D11Texture2D using:

 texture->Resource->TextureRHI->GetTexture2D()->GetNativeResource();

In the next step I plan to use interop to access the Texture:

 cudaGraphicsResource_t resource;
 cudaGraphicsD3D11RegisterResource(&resource, (ID3D11Resource*)D3D11Texture, cudaGraphicsRegisterFlagsNone);
 cudaGraphicsMapResources(1, &resource);
 ...

But unfortunately I get the Error 11 when I use cudaGraphicsD3D11RegisterResource which means "invalid parameter" and the engine stops working after accessing the resources (cudaGraphicsMapResources)

Would be very nice if someone here could help me :)

Best,

Product Version: UE 4.21

I am trying to do the same thing. Also failed at registering the resource with the same error.
