The texture for the Drawable must be set in a parent node (the Geode that contains it, or possibly some Node higher in the scene graph). You can use osg::Drawable::getParents() to work your way up the scene graph until you find the StateSet that sets the texture. Note that OSG combines StateSets, so even if you find a StateSet it might not specify the texture; it all depends on how the model is structured. Also, that part of the scene graph could occur multiple times in the scene graph if it is instanced (which is why getParents() returns a list: there could be more than one parent).
