As others mentioned, there is a bug related to your T600 mod.

just wanted to let you know that your t600 has missing textures for the windows and pink

I love your T600 for ATS! It seems that since the last update there's a texture issue with the driver and passenger window, it just shows the pink texture instead of transparent. Right now it's not usable because of that, hope you can look into it :)

hey could you add the painted bumper w/o fog lights

noticed how very little appreciation the author got so thanks for the amazing T600

Legend !
