Hi Fred, sorry, I don't have time at the moment to check your code. I just remember from past experience and bug reports to NVidia that OSG does not reuse FBOs for new cameras, so it's quite possible one can run out with the video driver complaining/crashing. The limits were also different

Hi, John Error log looks like shader uses vertex texture fetch, and you should use texture2DLod instead of texture2D, because in vertex shader GPU doesn't know which mipmap to use. It has no way to compute the lambda factor. You need to choose the mipmap in the VS yourself. So either there are
