Initially:
Why I started working with Povray?
I was interested by possibility of application to object of several materials
with various characteristics:Glass with a color pattern, on it mirror patterns
from silver, on mirror patterns blackening (oxygenating)

Blender internal render is able to draw it, but without photons, without
caustic, without iridescence
Povray is able to draw it, with photons, with caustic, with iridescence.

For this purpose it is necessary to use textural maps
I turned on at once two maps in function of write of the file, it is so simpler
to operate process automatically
If material 1, textural map: rgb 0, if materials 2 - textural map: image
If material 1 and textural map: rgb 0 - can, it not rational (record or write),
but this process doesn't take a lot of time, but relieves the programmer of a
difficult code

Now for me the main problem - to create a preview of the patterns built in
Povray by means of any crutch as I am not a professional in the field of
programming. It is simple my hobby, I don't know much.

After that it will be necessary to clear, correct errors, to establish rational
parameters by default, and, it will be possible to try to create very good
scenes

My version of the exporter is based on the official version, I didn't write a
code from a blank sheet, but... the official version seeks to tie the Povray
parameters to the Blender parameters that absolutely irrationally and doesn't
allow to use all capacity or Povray force

I connect the Povray parameters with the Blender parameters only to create a
preview of materials in Blender. The preview of the materials surface with
textures like image from file is already available:
