This year I included every driver who's model the game attempts to load, since the rating stuff the script handles differently, so each driver can have independent rating. Think there was only like 2 other drivers who didn't have any model data so I didn't include them.
But for the pre-2021 drivers, since the model data is not fully compatible with modern ego engine, the plan is to use closest looking generic driver model with the textures of the pre-2021 driver, to hopefully serve as "good enough" replacement.
And currently I'm roughly halfway done with porting all the missing faces.
Also bit of a shoutout
@Cynon for noticing that Ocon has a customization slot assigning him non-custom byte helmet, which is actually his helmet and not games 20 random design ones like it was last year, after which I did some digging around and confirmed that this year, it looks like most if not all pro-driver helmets have non-custom byte helmets, I am in process of compiling the list of them, so I can include them as a dropdown option for customization, and we no longer have to deal with the custom helmet shenanigans, tho custom helmet stuff will still remain in place for those who wish to use it, the only difference will be that you will have also ability to select non-custom pro helmets.
