NOTE:
Before i create a class called MyBlendSpace, then vs2015 cant compile this class and i deleted the files by hand. Why this error? where do UE4 recall this header?

Thanks.

Hey frawe-

When you deleted the files for the class, did you do so through Visual Studio or from the project directory? After deleting the files, you also need to right-click on the .uproject file and select “Generate Visual Studio project files” so that VS updates and recognizes that the header/source files were removed from the project.

thanks a lot.
