Hello, Problem I have is you: In the mod I have 12 cars and each illuminates the headlamps and rear of the first car, which does not light each lamp corresponding to each car individually. Any idea or solution?

If I understand your question correctly, you have 12 cars x 2 headlights x 1 taillight = 36 spotlights, but you're not seeing that many actual lights. That is because we limit each pixel to 8 spotlights, we try to pick the closest and most relevant 8 from the total, but don't always get it perfect.
