Hi Paul, The TexGenNode should work just like the LightSource. It affects all nodes in the scene graph expect those with GL_TEXTURE_GEN_... set to OFF. So... I've no idea, too, about how to use multiple TexGenNodes to handle different generations in your shoes. :-)
A possible way may be to apply two TexGen attributes to nodes and handle OpenGL's positional state issues in callbacks. But it will be much better if we could still make use of TexGenNodes.
