Solved Help, the skin isn't showing up.

Just by looking at the files, the textures path are wrong in the materials.cs

Code:

   overlayMap[2] = "vehicles/van/van_skin_Secret Labs.dds";

No such file exists in that location.


Corrected is

Code:

   overlayMap[2] = "vehicles/van/Secret Labs/Secret Labs.dds";

In general, check the game's console. It will tell you what could be wrong.


Also, you have this line:

Code:

   specularMap[2] = "vehicles/van/Secret Labs/Secret Labs.dds";

Although specular maps are something particular. Here you are just re-using your skin texture.
Unless this is intentional, you don't want to do that to avoid strange effects.

 

I suggest to change "Secret Labs" to let's say "Secret_Labs" this way you will make sure the name isn't a problem also when you're setting up your materials you have to also map the material.
so this: mapTo = "van.skin.YOURSKIN";
should be changed to : mapTo = "van.skin.Secret_Labs";

other than that I do not see any issues, once you rename everything you named "Secret Labs" to "Secret_Labs" and fix the materials.cs file it should work fine.

oh, and move the materials.cs file to a subfolder so it does not overwrite anything.
