Aladdin 4D objects do not normally cast shadows! Under most circumstances this is not noticeable, and you save the extra calculation time. But if you just have to have shadows cast by objects, there are several things you have to do: In the Attributes list of your shadow-caster, you have to check Cast Shadows (and maybe Self Shadows) In the Attributes list of the objects that will be shadowed, you have to check Receive Shadows. If you are using local lights, the local light must be set to Cast Shadows. Finally, in the Render Settings, the permission flag must be set for Shadows.
