Hi Gustavo,
I’m learning to use Windywang’s plugin as well so I can do VR development without a kit. 
Using Windywang’s example, I was able to get Tilt values. Here are some screenshots I hope will make it clear.
The Tilt event comes from Input -> Motion Event, or you can log the values with Input - Motion Values.
Before this will work, we have to enable the Wiimote features. I am not sure if the character creation section is the best place, maybe Level Blueprint would be better?
I hope this is useful. This worked on 4.11. Good luck!
Thank you Windywang for creating this plugin!
