Hi
in c4d one usually stacks for such things full materials, as mapping is in c4d only per material.
stack several materials and use the "mix" button in each stacked in the material. the more right in object manager the higher up the material is.
use alpha cutouts to make parts transparent to show the mat below.
each then can have its own mapping and can make what you want.(decals , stickers, text on other objects and so on) etc
Corona supports this nicely.
cheers
