the warnings come from glGetError() calls OpenSG does at a number of points (e.g. StateChunk activate, end of frame, ...). Since OpenGL errors are not very descriptive (e.g. the one you are seeing just says that some GLenum value was out of the expected range for the call) unless you can pinpoint the call that caused them, you'd first have to find that call. On linux you can use bugle (<http://sourceforge.net/projects/bugle/>) on windows can try glIntercept (<http://glintercept.nutty.org/index.html>) or a commercial GL debugger if you have it. All should be able to indicate which OpenGL call was passed incorrect parameters. From there it should be fairly simple to deduce the OpenSG field that is set to the incorrect value.
