Same issue as ZetaVasuki, cars only have half the livery essentially, it's all in dots/lines.
Only other mods I have on that effect McLaren are "Lando Norris 2024 Helmet by Little0nion", "MADM_P" (to add in O'Ward - which is missing his name for some reason), "NorrisSkinColour_P by TCSSkin" (To fix Norris' skin tone), & "FineTunedDriverPortraitsbyRolfeee_P" (to sort out the portraits).
Every other PAK is made by you for 2024 season, cars and helmets, and they all work perfectly.
