Hi , thanks for your answer. Unfortunately, ProceduralMeshActor.generated.h is not found when I include it. I added ProceduralMeshActor.cpp and ProceduralMeshActor.h manually (not via the feature in the editor). Can you tell me how to force the compiler to create the *.generated.h file?
EDIT: Okay, I had to regenerate the Visual Studio Project from the editor, not the header file is generated and the macros are accepted! Thanks a lot!
