Hi Riccardo Linux Fedora 7 OSG 2.2 NVidia GeForce 8800
All work fine for me. I just do "osglight_modified cow.osg" I join the osglight_modified.cpp simplified and updated to OSG2.2. Many bug has be fix and feature added since the OSG 1.2 Version. Perhaps an update to OSG 2.2 will be a good choice for you.
