What is the best way to do this? I was thinking of connecting up to 4 USB controllers via a hub to a mac or pc, and was wondering the most effective way to:
Manage input from several controllers, and take full advantage of their functionality (nothing too crazy here)
Render to multiple viewports
Understand if Unity is even set up for this type of configuration.
Any ideas or help are hugely appreciated! Thanks in advance.

Unity can get input from four joysticks, but you will need to configure each with its own axes in the Input Manager. Rendering to multiple viewports is also straightforward. A camera has a property called Normalized Viewport Rect that defines the onscreen rectangle in which that camera renders. Its coordinates are set using fractions of the screen width and height, so a width of 0.5 gives a viewport that is half as wide as the screen, etc. You can add as many cameras as you like to a scene and render each to its own viewport.
@Andeeee - I have a related question: Unity can support up to 4 separate joysticks and it is limited to 8 joystick axes and 20 joystick buttons. So is that 8 axes / 20 buttons -per- joystick or a total of 8 axis / buttons -total- for all joysticks?
I think it is rather 8 axis and 20 buttons per joystick (it would be madness if those were to be distributed…).
“Distributed” was my understanding of the limitation, but I haven’t tested it. You’ve piqued my interest on this, I’ll have to dig up a couple joysticks and give it a try.
I doubt it isn’t distributed. But I hope it isn’t.
