Notes from (16.02.17) update:
Visually. There was done complete revision, optimisation of whole model, materials and all what is connected to. Some parts were replaced. Wheels reworked and resized to looks, as they should. Maded animation for lights trigger. Dashboard was retextured with real elements and digital instruments updated. Interior have more realistic view and now we can customize it with various leather color combinations. Which is already done for most of paints. All skins folders cleaned and some colors of paint are new there. The difference you will see from first touch.
Sound. Project "migrated" to last recommended version (complete support of 1.12) and sounding is improved.
Physics. Tyres, for sure, update to V10. Engine power output recalculated with normal for BMW drivetrain loss about 14%. Still the beast BMW if keep in mind the weight of model. Suspension was a part, which is took most time of update - was about all, except the geometry and there new tune/tweak of all parametrs and basic alignment. In part of physics data files were reviewed (as almost always in last updates), different changes and tweaks in all needed places.
For what? - to make it better or to try get best from it. Hope, it have a chance to become your favourite BMW in Corsa 1.12
