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 }}
