Using relations I’ve been able to use a joystick to drive various skeleton joints/blendshapes at live time. What I haven’t succeeded doing is reversing the direction that a device drives a particular attribute. An example: I can create a relation so a joystick drives the rotational value of a head to look up and down using the forward/backward direction on the joystick. When the joystick moves backwards the head travels upwards, then when the joystick is pushed forward the head looks down. Does anyone know of a relation that can be used to reverse the direction the joystick travels?
Sorry for my bad English, I use google trans.
To reverse a value, simply multiply the value by -1.
I hope I helped you!
