The value returned by ``O.materials.append`` is an ``id`` of the material, which can be also passed to :yref:`sphere<yade.utils.sphere>` -- it is a little bit faster than using label, though not noticeable for small number of particles and perhaps less convenient. -If no :yref:`Material` is specified when calling :yref:`sphere<yade.utils.sphere>`, the *last* defined material is used; that is a convenient default. If no material is defined yet (hence there is no last material), a default material will be created using :yref:`defaultMaterial`; this should not happen for serious simulations, but is handy in simple scripts, where exact material properties are more or less irrelevant. +If no :yref:`Material` is specified when calling :yref:`sphere<yade.utils.sphere>`, the *last* defined material is used; that is a convenient default.
