Even the finish is just basic, wanting to perfect it

Maybe I tell you things you know, but if you want to improve the mesh, which is
clean (and it's an advantage) you can use MeshLab, without going crazy by hand.
It has many remesh options, most of the time unsuccessful, some options can
work...
Mesh step Mesh otherwise you lose the colors

I like the cars, and so do the people. My expectation was not that I would be
able to zoom in properly. For reasonable scenes, you simply need many different
models, and the BMW in particular does really well.

The BMW, is that the final version?

I wanted to work on it somewhen in the next few days, split the meshes, change
Color and so on. This costs several hours, and I would not like to do it several
times for the same model.

Unfortunately, I don't know how to model, so I don't have any mesh products to
show. For me, everything consists of cylinders, boxes, spheres, with very lousy
textures around them.
We have to be that honest.

But my programming works fantastically ;)

Greetings, and I hope for more Cars and Persons.

Yes, you are right, it is a final version, because I have other cars and people
that I want to improve, and the BMW, although simple, is clean. Tomorrow I will
try to see if I can increase the polygons while maintaining the colors, in a few
automatic steps ... but I cannot guarantee, many transformations must be
crossed. I will let you know soon.
BR!

Unfortunately as I feared I tried with MeshLab to increase the resolution, but
it introduces errors.
As I thought it loses the border between the colors and also inverts (!!) some
faces.
This is the reason why I always work with my tools. I have an idea, in the next
few days I will implement a new feature. It takes the object and extracts the
files divided by color. In this way you can improve the parts that need it and
then it is easy to join them!
See you soon!

I just had a look at what installing MeshLab would entail, but the above changed
my mind :-).

still, it's true when you write "...but if you want to improve the mesh, which
is clean (and it's an advantage)...", therefore I suggest:

if you can export a mesh to a GNU/GTS, that library has loads of tools to work
with clean (and not so clean :-)) meshes.

and this is where I cannot "follow", why "by color" ?  why not "by component",
and leave texture/colourising for when the object is used ?

Have a look at this page :

A Catmull-Clark Surface Subdivision Suite macros.

This may help you

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

I explain my working method.
Each layer represents a component, obviously it has its own color. Here I have
activated ALL the layers, but obviously I hide the ones I am not working on.
It is a very practical method. For example, I can disable everything and leave
only the red lights visible, or the bodywork. From the CAD with my tools I can
output in many formats, preserving the information on the color and
transparency, because they are the name of the layer.
What I have to do is implement in the layer name, which declares RGB and ALPHA,
also the name of the object. So that in the povray file you can easily treat the
"finish" by identifying the object. For example, on the bodywork, apply its own
non-standard level of reflection.

Each layer, when the parser creates its mesh, contains one and only one. In this
way I can decide if the parser creates it with triangle or smooth triangle. It
depends on the object, if it has to be tapered.
