I started gathering some info for this thread .. several weeks ago .. as I said I would do a short ( maybe not) TUT on how to do some UV/ Rendering techniques in Rhino ( and others ) for better renders of your 3d works. Zathros kindly sent me a Rhino file to use which I will, at some stage, but while looking at his file I ran into a few snags that I had to work out, as I wanted to make the TUT as simple as possible and yet help make your renders as best as possible with the least amount of damage to brain cells, and not turn it into a modeling tutorial as well! Sorry, some parts of your brain are going to suffer! in fact, before I finish this sentence, the rendering processes out there have more than likely have already changed drastically! Things are just moving that fast!
This is not specifically aimed to get a textured model for papercraft! That may or maynot be possible! Some things in here will help, some objects and the way virtually all rendering is moving does not produce a PHYSICAL printable image! There it is! That includes Rhino, thought they are several YEARS behind all others in that respect, in all render capabilities.
First off some terminology. We used have mostly 3 images when rendering, and still do in Rhino.
A Color Map, or what we used to call a Diffuse Map, is now called ALBEDO.
A Texture Map, or what we called a Bump Map, is now a NORMAL.
and a Transparency Map, called the same but is now called a MATTE.
That would get us by in the old days, but today most everyone is focused towards Gaming or Game Engines, and the highest render quality possible at the smallest computing cost, no longer using GPU but CPU rendering!
Take a look at this, which is a very recent game, using Unreal Engine 4 ( free by the way, Unreal, not the Game), that pushes the rendering way past anything before and in REAL TIME!

Now look at the mesh.. and see I took just a part of the mesh and only added some of the textures, in Rhino..
You have to remember Rhino only uses Albedo Bump and Transparency!
Under normal old timey rendering ie-raytraced of years past this would take hours to render!
Next time we start with some basics... in Rhino and in Blender
I have most other software but I will only do this TUT with those two. I highly RECOMMEND if you want to render your models GET BLENDER! IT'S FREE!! https://www.blender.org/

, then we all ready know you have a program..duh! So... you do a render view.. not to bad huh? Could it be better, OCD LIKE ME, always! Or perhaps you downloaded one and it does nothing...DARKNESS!! BLACK!! NADA!!
