I have a sensor that is feeding quaternion data into max. I'd like to have a button that repositions the orientation to a center position so that all movement of the sensor is relative to that center position. I know how to do this in Euler (get axis value when button is pressed and then subtract from incoming values), but I'd like to stay in quaternions to avoid gimbal lock. Does anyone have a good method to make this work?

I believe what you want is quaternion multiplication (offset one quaternion by another), so 

 is the object to investigate. simulated example below:

Yeah thank you. I figured out my problem. I found that it’s important to get the multiplication order right. The inverse quat must be Quat 1 in the multiplication or it won’t work correctly.
