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"

How to define a Volume in a plugin?

I'm trying to make a plugin and I wanted to have a custom Volume that comes with it. However when you drag the volume into the world, the ABrush::UModel::Brush and ABrush::UBrushBuilder::BrushBuilder are both null after they've been fully constructed.

After doing some debugging, the best reason I've been able to find is that this line will fail IsChildOf( AVolume::StaticClass() ) I assume it is because a class defined in a plugin is invalid for this call. Do you have any suggestions for what I can do to get around this issue OR should this be logged as a bug?

 bool UActorFactoryBoxVolume::CanCreateActorFrom( const FAssetData& AssetData, FText& OutErrorMsg )
     if ( UActorFactory::CanCreateActorFrom( AssetData, OutErrorMsg ) )
         return true;
     // this line fails
     if ( AssetData.IsValid() && !AssetData.GetClass()->IsChildOf( AVolume::StaticClass() ) )
         return false;
     return true;

Just to be clear, everything works correctly if I place the class in the project root, but not if I place the class in a plugin.
