Hello, I isolated the headlights of the cars and turned them into mesh lights in order to achieve night-driving effects. But my mesh lights are flickering when I rendered them. I uploaded the frame 509 and 510 to show the difference of intensity of light. Settings are the same but the intensity of light is changing. Can you please help me to fix this?

I think I just found the problem. The number of cars always changing in the project. So area of mesh light is also changing. Thats why I am having flickering
Disable normalize on the mesh light, it will not change the intensity when new cars are added
For ease of use, I would use area lights in this situation. You could probably need fewer light samples too. I like the style btw!
