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

reflection {

}
conserve_energy
}
normal {
bump_map {

}
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... ;)
