As the title says, it is odd that the blueprint nodes used to spawn objects show abstract classes.

I want to hide these classes to prevent Blueprint users from trying to spawn abstract c++ classes when they should be inheriting from them instead.

This article displays the UClass meta tag " `DontUseGenericSpawnObject = "True"`" which … does nothing?
