[osg-users] OSG 3.0 and osgShadow texture unit problems

Hi, I had some shadow code that was working well on 2.8.5 but will not work on 3.0.0. I verified that the same problem occurs with the OSG shadow example source. My test machine GPU (Nvidia) reports 16 texture units available. If I set the shadow texture unit number to anything higher than 7
