This is for manual installation.
But I also plan to create a copy and paste version, maybe a modular mod version as well.
I borrowed the instructions from StrongestFish Damage Mod. Thanks to StrongestFish for the guide, not me.
1.Install skin mod first.
2.Download Ego ERP Archiver 7.1 or newer here:
This program lets you export and import resources from ERP archives for EGO engine games.
ryder25.itch.io
If you do not want to pay, then click little line "No thanks, just take me to the downloads"
3.Open folder Steam\steamapps\common\F1 2021\2021_asset_groups\f1_2021_vehicle_package\teams and find erp file of each team.
For example Ferrari: Steam\steamapps\common\F1 2021\2021_asset_groups\f1_2021_vehicle_package\teams\ferrari\wep\
ferrari.erp
4.Open erp file in Ego ERP Archiver, in tab Xml files - click .vtf file (for example ferrari.vtf), click xml files -> import, and choose xml file from mod. Mercedes.vtf located into
Common.erp, not in
Mercedes.erp.
5.Save and repeat for each team.
