     Kind of. I found a nice snake skin texture on the net, but it was 
fairly large. I played around with that for ages and couldn't get a good 
result, so then thought about trying with a smaller image, so I cut out the 
attached from the original and tried with that. It worked first time!  :oO

      Set yourself up a torus (whatever) and apply this:

         T_Gold_2A

    finish{
      diffuse 0.45
      ambient 0.035
      phong .5
      specular 0.6
      reflection {
        0.8
        metallic}
      conserve_energy}

      normal {
      bump_map {
         jpeg "snake_tex4.jpg"
         bump_size 1
         interpolate 2
        map_type 3}
        scale .47   rotate <0, 40, 0>}
        finish {ambient  -.055 phong .5 }}

       Have fun!

Last one, I promise! :o)

   This is a single coil version with Garnet eyes.

Well, don't stop on my account, they just keep getting better. Surely this
is just the kind of image that the POV-Ray news server is meant to host!

It seems from some of the previous messages that you make the rings in
reality. Is this true? Are you rendering it in POV-Ray for fun, or does it
really inform your design and construction? Do you make blueprints somehow
and use them for the metalwork? (of course, you can ignore these very nosy
questions if you wish, craftsmens secrest and all...)

If I was your client, I would want this one. I think the single coil is more
elegant and works better.

Definitly keep it up, and thanks for sharing. Do you happen to have a
website where you put POV-stuff?

-Stefan

Wow Steve. These rings are amazing. Great job. :)

    Well, yes, I hope so!  :o)

   Yes, that's what I do, I design and make jewellery. I'm just about to 
start making this single coil snake ring in silver, so I'll post an image or 
two on my little personal website when it's finished.

> really inform your design and construction?

  Well, I've found that I'm using PoV-Ray a lot more now for jewellery 
design. Yes, it's fun! Last week I designed 5 rings and a pendant and 
earring set. That was the best and most enjoyable weeks work I've done for 
some time. Getting paid to play with PoV-Ray is good!  :o)

      Oh, I don't worry about that. Basically, there are no blueprints as 
such for most common jewellery items, but when it comes to something that's 
going to be an expensive design, then sure, you either draw it correctly, or 
make an exact silver model so that the customer knows exactly what s/he is 
getting.

     It does work better. I was a little ambitious with my first snake... 
;)

  My pleasure. As long as my work is (sometimes) enjoyed, I'll keep on 
goin'!  :o)

    Oh, now you've gone and said it Stefan. ;)  I don't at the moment, but I 
now have many images, so I guess I should. I'll post a link sometime in the 
near future.

Steve, I for got to ask and now I am wondering, what did you use to do 
the UV mapping?

Wings? ...or something else such as UVmapper?

      Hey Jim, yes, I used Wings. I did it in reverse to the norm(?) though, 
I mapped and unfolded the flat inside of the snake to give it the normal 
gold texture, and then applied the bump_map to the outer, scaly, skin. 
(Doing it this way, I saved a whole heap of time by not selecting a trillion 
faces!) :o)

 //Material definitions =====

 // flat inside of snake

#declare Cube7_sep8_auv=texture{

  pigment{ colour Pink}

finish{
      diffuse 0.3
      ambient  -.055
      specular 0.6
      phong 1
      reflection {
        0.8
        metallic
      }
      conserve_energy
    }}


// Snake skin

#declare Default=texture{ pigment{ colour Pink}

finish{
      diffuse 0.3
      ambient  -.055
      specular 0.6
      phong 1
      reflection {
        0.8
        metallic
      }
      conserve_energy
    }
  normal {
      bump_map {
         jpeg "snake_tex4.jpg"
         bump_size 1
         interpolate 2
        map_type 3
      }
      scale .47
      rotate <0, 40, 0>
   }
   finish {ambient  -.055 phong .5 }}

I am not sure what you mean.

    Oh, well all I meant is that most people (I guess) would try and UV_map 
the actual outer scales of a snake 'first', which seems a bit like walking 
backwards on a high-poly  model when all you need to do is reverse the 
routine. So I just UV_map the inside (see attached), export, and then open 
PoseRay to give it a gold texture on the inside, and then apply the same 
gold texture and bump_map to the outer surface -  rotate the bump_map until 
satisfied, and it's done.

     My workflow is this:

       > Select faces
       > Select .UV_mapping.
       > Select Continue
       > Select Unfold
       > Export to .obj
       > Open .obj in PoseRay
       > Apply textures

     But yes, I used Wings...   ;)
