m3gt2 thanks! Yes, now parameters of light emitters, such as their position, color, spot angle, horizontal cutting edge, are being guessed based on coffee goo and some other sources. It might not always be accurate, but at least it’s diverse, and it’s way better than hard-coded parameters for 911 Carrera S. 
Those lights in screenshots with Ferrari and Audi, in the top post, were guessed. Of course, it wouldn’t work here, for example, I don’t think there is a way to find parameters for something like that light shape automatically:
But even here, it’s easier to just re-define a couple of those parameters rather than set everything. By the way, if you create a folder Documents\Assetto Corsa\cfg\extension_cars_guessed, all guessed configs will be stored there.
