Description

Adding a new code class derived from AnimInstance will cause the Visual Studio build to fail in a project based on the code Vehicle template. The build errors indicate that there are problems in the ShowFlags.h file:

  2. Build the project in Visual Studio.
  3. Open the project in the Editor.
  4. Add a new code class to the project derived from AnimInstance.
  5. Close the Editor.
  6. Build the project in Visual Studio.

RESULTS:
The build fails.

EXPECTED:
The build succeeds.
