360 Controller in Maya
Honestly, this is exactly what you were looking for. You were looking at your $1500 copy of Maya, and thinking: why can't I control this with my $20 USB Xenon controller? Wonder no more: ControllerServer is here!
This is a little one-off that I did for Steve the other day that's kinda fun. It allows you to connect your 360 controller to Maya as a Motion Capture device. The inspiration for this was Joystick Server, by Jorge Luis Imperial-Sosa. Sadly, Steve wasn't able to contact the author, and there were some limitations in the program that couldn't be worked around without the source (e.g., Joystick Server doesn't expose buttons or analog triggers), so I banged this out for him, and cleaned it up for release.
Pushed into the public domain, for the 2 other crazy people that want to prototype game controls in Maya. Should be easy to modify to use general purpose DirectInput devices, or multiple controller inputs. Just think, with 2 controllers, you could use Maya to play the world's most overpriced game of Pong!
