Hi Gerrick -- To clarify, at the top level node of you model, get its StateSet and do this: setMode( GL_NORMALIZE, osg::StateAttribute::ON ); Alternately, if the scaling is uniform in all axes, you could rescale the normals instead, which might be more efficient for vertex-limited rendering: setMode( GL_RESCALE_NORMAL, osg::StateAttribute::ON ); The difference is that the former is almost universally implemented in OpenGL with a per-vertex sqrt, whereas the latter is typically implemented in OpenGL with a per-vertex scale (multiply) and is therefore less expensive.
