Use the template to make your livery.

Once you've finished editing your livery, save it as DXT5 with the name
"z28_sign_2" without the quotes or a higher number if there's a livery
with that number already.

Add it to z2879.ytd in mods/update/x64/dlcpacks/z2879/dlc.rpf/x64/vehicles.rpf
and save

The livery template is only in 2k since I'm not a fan of 4k textures which
causes many problems. 

Have fun!
