It's already drap and drop:) Just copy the incardriver_f1.erp file to C:\Program Files (x86)\Steam\steamapps\common\F1 2019\2019_asset_groups\animation_package\scenes\incardriver\2019 and the mipmaps files to C:\Program Files (x86)\Steam\steamapps\common\F1 2019\character_package\drivers\male\unbranded_gen_19\textures
Hi, I found a problem with the mipmaps files. I will update the files this afternoon. In the meantime, it should still work if you install it with the Erp archiver
