I apologise if this has been discussed already, but I couldn’t find any relevant topics pertaining to the question. I have a custom design on the Cadillac Escalade that has a thick stripe decal on both sides of the car of the dark wood texture/special colour. However, when I pull up the design editor in-game to try and create a similar design on my other vehicles, I’m not able to use the special colours; not the wood or even the carbon, gold, aluminium, etc.
Am I missing something?
