Hi Edwin, renderbuffer's are strictly a FBO feature that you can't attach to general graphics context so won't work if you just attach buffers to a viewer's main Camera that is attached to a GraphicsWindow. To use the feature you'll need to create a rendering to texture Camera which has render buffer attachments and separate Camera attached to the GraphicsWindow that does the final renderer. Have a look at a examples like osgdistortion or osgmultirendertargets.
