Great mod, although i have been having one annoying issue recently. Every now and then when the various truck configs spawn in traffic, wheels and/or bumpers end up in goofy colors. Some D-series configs are horrendous about this as the whole cab changes color, the T-series gets funny wheels and/or bumpers, and the MD-series gets weird wheel colors. I have a suspicion it’s the new paint system in 0:37 that’s causing this mess.
Some of my T-Series and MD-Series configs use colourable bumpers and wheels, which had to be manually coloured by me to match the skin. While these colours are preserved when loading a config from the vehicle selector, the traffic system selects random colours when spawning and respawning traffic. I'll try to see if it's possible to prevent the colours on a config from changing in traffic.
Knowing the game itself, you may have to make the affected parts' coloring be covered up by the skins somehow. That's pretty much the only permanent solution, I fear?
