Hi Andres, the CameraManipulator in use ( I guess it is the default Trackball ) gets the center of your scene - when you load multiple models it gets the bounding volume of all of it and set it as a home position. You can change the center of rotation to something else by calling setHomePosition(...) which is a method of the CameraManipulator. Something like:
viewer->getCameraManipulator()->setHomePosition(...)
