Apologies if my initial question threw the thread off topic but it was a genuine one about Feldbergring. I recently looked into modifying the headlights of some mod cars and was messing around with the lights patch files assuming I could adjust them from there only to find out it is part of the car mod (lights.ini or something, packed in the data.acd or kn5) I have never messed with any track files so had no idea whether it was a lights patch or track specific thing that would make lights like fires or lit windows possible at Feldbergring (my query is specific to this track really) so I posted here and in the lights patch thread on the AC forum. I wasn't sure if it was A. something I could do for myself already in the lights patch settings B. something the track maker would have to do or C. something that would have to be implemented by x4fab in which case I would post over there to see if it has crossed his mind to add flickering lights.
