MainView and getEuler

Dear Vizard Staff,

I have a question I'm sure you'll be able to wrap up easily.

I have a viewpoint being controlled by an XBox controller:

Code:
#Move locally in the Left to Right Direction self.viewport.setEuler([self.gRotation[0], 0.0, 0.0], viz.BODY_ORI, viz.REL_LOCAL)
		
#Move globally in the Up to Down Direction
self.viewport.setEuler([0.0, self.gRotation[1], 0.0], viz.HEAD_ORI, viz.REL_LOCAL)
			
#Roll
self.viewport.setEuler([0.0, 0.0, self.gRotation[2]], viz.HEAD_ORI, viz.REL_LOCAL)
The problem comes up when I am attempting to save the orientation of the MainView for another program using this script.

When I try and use getEuler(), the values I get back do not match the actual orientation of the MainView.

I've tried using the masks for the body and the head, however I still can not match the original orientation.

Is there a method to concatenate the matrix transforms so I can get the final orientation value to save the orientation?

It's hard to tell what the problem is without more information or sample code. Either way, I would recommend using quaternions (getQuat/setQuat) to save and restore orientations.
