because I use objects, and dividing the components related to the mesh is the
best way to be able to vary colors and manage the smooth. The smooth must have
edges that correspond to the change of material. This is also the reason why, if
it is true that it is possible to multiply the faces, this must be done in an
"intelligent" way, that is, preserving the edges. Then there are many methods
and algorithms.. but they do not work as I intend
