I have a character where the head gets a "skintext" skin texture. The neck
gets a gradient y pattern, which is supposed to demarcate between a black
ring at the bottom (end of costume) and the start of the exposed flesh.
Note how the finish is "wrong" over the exposed neck.
Am I doing something wrong or this this a problem?
// relevant code pasted
#declare masktext=texture{pigment {rgb 0.1} finish {phong 2}}
#declare skintext= texture{
pigment{skinpig}
finish{ambient skin_amb diffuse 0.69 specular 0.1
roughness 0.5 phong 0.1 phong_size 7 metallic 1 }
normal{granite 0.07 scale 0.1}
}
#declare necktext=texture{
gradient y
texture_map{
[0.5 skintext scale 1/40]
[0.5 masktext scale 1/40]
}
scale 40 translate 2*y
}

Perhaps I'm way off the mark, but generally I would say something like:
[0.50000 skintext scale 1/40]
[0.50001 masktext scale 1/40]
I'm not sure if that helps at all.

Thanks but i) I think my original is a preferred and acceptable usage and
ii) making that change didn't fix the problem. Thanks anyway.

Your model is made of blobs, correct? Is the texture applied to the
blob components, or to the whole blob?
I get no problem with the texture mapping when applying it to a sphere
or cylinder, so I suspect your problem is in how textures apply to blobs.

Yes, it looks exactly like classic blob texture blending...... when one
blob component uses a different texture, and that texture is
interpolated smoothly to the next blob component's texture.....

Welllllll, I just tried a reduced code on both a blob cylinder and classic
cylinder, and it behaves as it should. Perhaps there's a code bug in the
construction of my character somewhere. Thanks for checking, guys.
