Hi Hartwig, Eye linear TexGen is positional state, that in OpenGL requires you to apply a specific modelview matrix prior to doing the glTexGen - it's the TexGenNode's role to provide the way of telling the OSG's rendering backend which modelview matrix to bind to the osg::TexGen (and associated

Hi Serge, Enable the unref image after apply in your case is a bit awkward as, as you have found, the mechanism assumes that all contexts will require the texture. Another way around the issue is to use the texture object pool to keep a cap on the memory usage on the driver and GPU side.
