Hey,
have you tried the following Tool: "ColTexMaker - V2.2.1" from Eagles Eye? You should find it via the searchbar in the Webdisk.
I have tried it quickly (as I actually was expecting an error, cause the tool does not like red colors
) but it worked surprisingly well!
paulorossini you can just download the tool and throw it in there, it is a matter of seconds. You'll just have to copy paste the area of the rear lights into the created Einfärbetextur, but the rest works very good on that texture.
