you have lots of zero's in there...
but your first question was about having objects with 2 materials
so does this means you want to map each sphere with a dark and a
bright side?
Personally I would use normalmap+dot3material for this and use Prefab
to render map with shadows off for the tracer.
It can generate the normalmap for you as well, but since its a sphere
a single small map can be generated runtime at very low cost (only
once for all spheres).
using NormalMapGenerator or NormalBumpMaker, both in materials.utils
here a year old example using this combo
http://www.closier.nl/playground/normalmaps2.html
if you want highly detailed map, Prefab can also raytrace it for you.

Hi Fabrice,
This is my code, I create two spheres to simulates the earth and the
moon, then I lighting these objects with a PointLight3D, but they are
seen with a flat aspect, I would like to have the same effect that I
have with the PointLight3D (the side towards to the sun lighting and
the other side dark), but with smooth objects.
I tried used a PhongBitmapMaterial with DirectionalLight3D or
AmbientLight3D, although i didn´t reached a good result. In fact, the
objects can be seen in a smooth aspect with these lights and
materials, but we cannot see the lighting differences between the two
objects sides.
Thanks.
Tiago.

Sure I wanna help you but in this case
this is pretty much all you need...
Show your code snippet where things go wrong or do not work
then I might be able to help you more.

you need to set the materials at face level.
Like mesh.faces[index].material = ITriangleMaterial

how can i associate two or more materials with the same object?
i want to lighting an object with a pointLight3D and an

using whiteShadingMaterial and phongBitmapMaterial.
thx.
