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"

SetTextureParameterValue not working?

This code just doesn't seem to work... more specifically the "SetTextureParameterValue" part, everything else works as intended. Code:

 UMaterialInstanceDynamic* MeshCompMat = Cast<UMaterialInstanceDynamic>(MeshComp->GetMaterial(0));
 if (MeshCompMat)
     UTexture* TextureSample;
     if (MeshCompMat->GetTextureParameterValue(TextureSampleName, TextureSample))
         UTextureRenderTarget2D* TextureToRenderTarget = Cast<UTextureRenderTarget2D>(TextureSample);
         UMaterialInstanceDynamic* NewMaterial = UKismetMaterialLibrary::CreateDynamicMaterialInstance(World, NewMaterialInstance);
         NewMaterial ->SetTextureParameterValue(TextureSampleName, TextureToRenderTarget);
         UKismetRenderingLibrary::DrawMaterialToRenderTarget(World, TextureToRenderTarget, NewMaterial);

Goal: i would like to copy the TextureSampleParameter value from the MeshCompMat to a TextureSampleParameter within NewMaterial.

Outcome: TextureSampleParameter within NewMaterial is always blank.

I'm using UE4.15.3

Product Version: UE 4.15
