    MatParam param = material.getParam("UseInstancing");
    if (param == null || !((Boolean) param.getValue()).booleanValue()) {
        throw new IllegalStateException("You must set the 'UseInstancing' " + "parameter to true on the material prior " + "to adding it to InstancedNode");
    }
    InstancedGeometry ig = lookUpByGeometry(geom);
