Pretty sure it was lights on the bottom of a hot air balloon, which is why this
reminds me so much of it.

Maybe Sven needs to add some light sources to the scene... :D

At the moment, all seems to point at the pigment definition as the
culprit, as that's the only relevant thing we've always changed. You
should at least /try/ it with a plain pigment, to either confirm or
refute this theory.
If you can confirm it, we know that's what we have to examine further;
in that case you'll probably want to post the image map at last, so that
we can see what might be so special about it.
Otherwise we can be sure that it's a red herring, and that we have to
dig someplace else.

You know you'll be going straight to The Hague for posting this, right?

I believe what's going on is your image map is too dark and there's no specular
highlight or phone home and load in your outer finish statement.
I'm not home to test that theory out.

You mean, I should use a different angle for the light source?

Nope. Here's a one-color pigment. :-(
texture source code:
------------------
#declare MyOuterBalloonTexture = texture
{
pigment
{
color rgb < 0.2, 0.9, 0.0 >
/* image_map
{
png "H:\My Documents\My Pictures\POV-Ray\Space - Launcher - Balloon -
Type 001 - Moon Runnings - Balloon Texture.png"
gamma 1
map_type 0
interpolate 2
once
}
translate -0.5
rotate < 90.0, 0.0, 0.0 >
scale MyRadius*2 */
}
normal
{
gradient y
normal_map
{
[ 0.175 PositiveBump ]
[ 0.175 NegativeBump ]
}
scale < 1.0, 1.5*MyRadius, 1.0 >
}
// finish { MyOuterBalloonFinish }
}

But I have a light source there. You mean, I should add more light sources?

":D" big grin face, so I'm sure Bald Eagle was jesting, at least mostly I'm
guessing.
Having seen your green balloon using that same bump_map... something is
obviously wrong. I think we have all had trouble understanding why it only
happens for you.
Is that version of POV-Ray official or custom?
Probably what we all need to know is at this point is if a test of a simple
normal statement on a simple object is okay or not.
Not knowing what else you've done to check what's going on, maybe forget about
the balloon for now and render this and you should see a bumpy ball (camera NOT
needed! default camera used):
#version 3.7;
global_settings {
assumed_gamma 1
}
light_source {
<-20, 40, -20>
color rgb <1,1,1>
}
sphere {0,1
texture {
pigment{ color rgb <1,1,1> }
normal { bumps bump_size 1 }
finish { specular 0.1 }
scale 0.2
}
translate <0,0,3>
}

No, sorry, just that there's nothing at all in your outer finish statement to
affect lighting and shadowing.
#declare MyOuterBalloonFinish = finish
{
// reflection 0.00
crand 0.10
}
#declare MyInnerBalloonFinish = finish
{
brilliance 1.50
phong albedo 0.05
metallic 0.00
ambient 0.00
emission 0.00
reflection 0.50
}
As you can see there, the inner finish does have highlighting via phong but it's
very little and can't be seen from outside (without transparency for outside).
