No, my project is in a different directory. To make sure that the solution rebuilt correctly, open up your project’s .sln, let’s call it MyGame. So right-click MyGame in Solution Explorer and go to Properties. On the left, under Configuration Properties, highlight NMake. Make sure that the Build Command Line option looks like \Engine\Build\BatchFiles\Build.bat MyGame Win64 Debug “$(SolutionDir)$(SolutionName).uproject” and not C:\Program Files\Unreal Engine\4.0\Engine\Build\BatchFiles\Build.bat MyGame Win64 Debug “$(SolutionDir)$(SolutionName).uproject” -rocket.
