I was able to compile the project however I having a difficult time following how the TestActorComponentVisualizer class is being used by the Actor in the project. I can find where BugReport01Editor.cpp references the TestActorComponentVisualizer class however I don’t see any other class referencing either of these. Since this is the only place in the code I can find a reference to your Component Visualizer, how is it being registered by the Actor in the project? Is the actor in the level an instance of the TestActor class? How would I create a new actor that used the TestActorComponentVisualizer in your setup?
