Hi Robert,

   I have tested again on some machines with Intel graphic cards.  The new change works on even both old and new nvidia drivers, but it does not work on Intel card.  There is no image showed on display with using Intel card.  You can reproduce the problem with the same test file on Intel graphic card.  Does any method make both Intel and Nvidia drivers working properly?  Thanks.

Hi Clement,

I have now ported the RayTracedTechnique shaders all across to use an int variable for the sampling loop and this fixes the hang when running with your model.  I have checked this fix into OSG-svn/trunk, 3.4 branch and 3.2 branch and OpenSceneGraph-Data/trunk.  This fix will required a OSG-3.2.3 release.
