This is pretty sweet! I want to make the NAPA autoparts car that Alexander Rossi drove last year but I don't have photoshop, or the talent. Do you think you could make it?
Then go to F1 2020\2020_asset_groups\f1_2020_vehicle_package\teams\myteam_honda (Honda in my case. Select your engine manufacturer). Then open myteam_honda.erp and look for the racenet livery and replace the livery_racenet_01_d and livery_racenet_01_s with the ones in the mod and save it.
