you can find the default 16C WA skin in the ShipTexturesBMP.zip as
f-16c-paint-def-r6.bmp.dds and f-16c-paint-def-l6.bmp.dds
and there is a sample (description and textures) in Bazar\Liveries\f-16a mlu\CMD extended skins for the 16A, you can use similar files for the 16C/16N as well
use "false" in the description, that will call textures directly from the folder where the description.lua file is placed
"true" call VFSTexturePaths (zip packs) from the Config/graphics.lua file
