[osg-users] [3rdParty/maybe OSG general] osgoculusviewer and View matrix

Hi all, in my app that is extension of osgoculusviewer I am using the ViewMatrix to compute some shader stuff. In one View (no slaves) setup it works ok, with the slaves it doesn't. Long story and debug, but I nailed it down to the ViewMatrix that is causing me issues. In my debug of the
