Hi Bart, I'm not entirely clear on your setup, but as a general comment, for selecting between different views you could have multiple View's in a CompositeViewer and switch the views on/off by set each View's master Camera's NodeMask to 0x0 or 0xffffffff to switch them on/off. Or you could simply copy the view and projection matrices from different sources to a single Viewer's master Camera. There are other ways you can do it as well, but personally I'd probably just opt for copying the appropriate view and projection matrices to a single master camera.
