I've decided to update the graffitis a bit. All graffitis now look a bit more worn (transparency change), some blurry graffitis removed (some of them still exists and in general there are still a lot of graffitis on the track) and the asphalt texture has been darkened to properly represent the real road. It's not a freshly repaved Nordschleife and it's most definitely not a recreation of the 2019 repavement (that'd require model changes and a lot of texture mapping). It's simply to make it look more real with the original AC graphics.
Please ignore the winter look that I have installed for Nordschleife, that is not part of my edits, you can find that on racedepartment.
In case anyone is interested in the roads alone and the graffiti mod, you can find the textures here:
You can combine it with the summer / autumn / spring / winter mod if you want.
