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"

Unable to serialize texture

Hi, I'm unable to serialize UTexture2DDynamic into array TArray which I would like to save to disk. I'm using following structure as child of FArchive.

 struct FImageArchive : public FObjectAndNameAsStringProxyArchive
     FImageArchive (FArchive& InInnerArchive)
         : FObjectAndNameAsStringProxyArchive(InInnerArchive, false)
         ArIsSaveGame = true;

Structure may be problem as well, not sure what type of Archive use.

 void MyClass::SerializeTexture(UTexture2DDynamic* Texture)
     TArray<uint8> ObjectData;
     if (Texture == nullptr) return nullptr;
     FMemoryWriter MemoryWriter(ObjectData, true);
     FImageArchive MyArchive(MemoryWriter);

     // do something with TArray<uint8> data

But after serialization of texture, there aren't valid data in my TArray. There are only 20 empty bytes and 4 bytes for "None" which doesn't make sense to me.

Does anybody know how should I serialize texture properly ? This way doesn't seem to work. Is Archive type wrong?

Could you at least point at any direction ?

Thanks, Jakub
