Skin for this car mod is invisible

This skin is in the parts list, but nothing changes when I select it. I couldn't find any tutorial on making skins for mod cars, so it might be a problem with the UV that I'm missing

Code:

"firebird_skin_transam": {
    "information":{
        "authors":"ehhi47",
        "name":"Trans Am",
        "value":120,
    }
    "slotType" : "paint_design",
    "globalSkin" : "transam",
}

 

For that example, you're missing brackets on the outside.

 

Thats just because there are other items in that file, it still has the outer brackets

 

The jbeam seems fine, can you upload your materials?

 

This is the material slot for the skin

Code:

singleton Material("firebird.skin.transam")
{
   mapTo = "firebird.skin.transam";
    colorPaletteMap[2] = "vehicles/firebird/firebird_skin_transam_uv1.dds";
    diffuseMap[2] = "vehicles/firebird/firebird_c.dds";
    specularMap[2] = "vehicles/firebird/firebird_s.png";
    normalMap[2] = "vehicles/firebird/firebird_n.png";
    diffuseMap[1] = "vehicles/firebird/firebird_d.png";
    specularMap[1] = "vehicles/firebird/firebird_s.png";
    normalMap[1] = "vehicles/firebird/firebird_n.png";
    diffuseMap[0] = "vehicles/common/null.dds";
    specularMap[0] = "vehicles/common/null.dds";
    normalMap[0] = "vehicles/firebird/firebird_n.png";
    specularPower[0] = "128";
    pixelSpecular[0] = "1";
    specularPower[1] = "32";
    pixelSpecular[1] = "1";
    specularPower[1] = "128";
    pixelSpecular[1] = "1";
    diffuseColor[0] = "1 1 1 1";
    diffuseColor[2] = "1 1 1 1";
    diffuseColor[1] = "1 1 1 1";
     specular[0] = "0.2 0.2 0.2 1";
    specular[1] = "0.2 0.2 0.2 1";
    specular[2] = "0.2 0.2 0.2 1";
    useAnisotropic[0] = "1";
    useAnisotropic[1] = "1";
    useAnisotropic[2] = "1";
    castShadows = "1";
    translucent = "1";
    translucentBlendOp = "None";
    alphaTest = "0";
    alphaRef = "0";
    dynamicCubemap = true;
    instanceDiffuse[2] = true;
    materialTag0 = "beamng"; materialTag1 = "vehicle";
};

--- Post updated ---

The car is my own mod, but I don't know how to make this car support skins, if that's the problem

 

Have you made the UVs yet?

 

I unwrapped the parts of the body that show up in a skin, baked them in a single image, "firebird_skin_transam_uv1.dds" which I think would be the UV. Then I put the colorpalette over it
