All of the tutorials say that installing ART in Maya is as simple as locating the UserSetup.py file in the ART folder, moving it to Maya, and pointing Maya at ART’s location when it asks. However, my C:\Program Files (x86)\Epic Games\4.12\Engine\Extras\Maya_AnimationRiggingTools\MayaTools folder contains no python files, and all the subfolders contain is an empty text file named Do_Not_Delete. Is there somewhere I need to be explicitly installing ART from? I always assumed it came installed with the engine.
