considering you're redoing the headlights, make sure you make the inside reflector faces vertical, so they don't look stretched. it's a subtle detail, but it will help to make them look more deliberate.
(slightly older picture without rudder jbeam) Still requires some trickery to get good pictures but it's a thing
Using TorsionHydros I made animated hands for the dummy with about 180 degrees rotation limit. Finished front interior collision too but not tested for most cars yet. Seatbelts also kinda work but not really, the seat just deforms and gets dragged with the dummy so they only help a bit. Seats should be stronger in this game. So now what is left is testing if this works for all cars, likely fixing many bugs which can take days, and maybe early alpha release of the mod? (Without 90% of the planned features, just the driver and standalone dummy that can't really stand straight unless on perfectly even flat surface.) Idk yet, people seem really picky for this kind of mods and they would ruin the ratings with 1 star reviews because there are no passengers yet. So maybe not on repo but forums only for now?
