How to remove trim for skin.

I recently made a skin for the grand marshall, and it turned out alright. However, when I equip it, the black plastic trim stays. As a police car, this doesn’t look good. Does anyone know how to remove the trim on the skin?

Here is a picture of the skin.

 

Change "fullsize_d.dds" to "fullsize_alt_d.dds" in materials.cs. Same with the others.

 

By others do you mean the other folders or the other fullsize_s, fullsize_c, etc

changed the fullsize_d.dds to fullsize_alt_d.dds and this happened

Changed all the fullsize_letter.dds to fullsize_alt_letter.dds and got this.

 

I don't exactly know what @Eleanor was referring to with "others" - only the "c", "s" and "d" need to be changed.

The reason this didn't work is because it's been entered backwards - it should not be 'alt_letter'; it should be 'letter_alt' (fullsize_c_alt.dds and so forth). As a result, the files don't load and you get the old orange NOTEXTURE material.

Here's what the code looks like for one of my skins for the fullsize that turns off the trim:

Code:

singleton Material("fullsize.skin.sampleskinname")
{
    mapTo = "fullsize.skin.sampleskinname";
    overlayMap[2] = "vehicles/fullsize/samplemodname/fullsize_skin_sampleskinname.dds";
    diffuseMap[2] = "vehicles/fullsize/fullsize_c_alt.dds";
    specularMap[2] = "vehicles/fullsize/fullsize_s_alt.dds";
    normalMap[2] = "vehicles/fullsize/fullsize_n.dds";
    diffuseMap[1] = "vehicles/fullsize/fullsize_d_alt.dds";
    specularMap[1] = "vehicles/fullsize/fullsize_s_alt.dds";
    normalMap[1] = "vehicles/fullsize/fullsize_n.dds";
    diffuseMap[0] = "vehicles/common/null.dds";
    specularMap[0] = "vehicles/common/null.dds";
    normalMap[0] = "vehicles/fullsize/fullsize_n.dds";
    specularPower[0] = "128";
    pixelSpecular[0] = "1";
    specularPower[1] = "32";
    pixelSpecular[1] = "1";
    specularPower[2] = "128";
    pixelSpecular[2] = "1";
    diffuseColor[0] = "1 1 1 1";
    diffuseColor[1] = "1 1 1 1";
    diffuseColor[2] = "1 1 1 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";
};

 

Thank you!

 

Yup, that's the way round it's meant to be. "Others" being "c_alt" and "s_alt". It's was very late
