So I tried to make the back lights flash red and yellow and blue and yellow instead of red and blue but nothing happend. Does someone know how to do it?
This is not always possible. Some lightbars or lightsticks are modeled so you can’t have more than 2 colors. Most of the time its red and blue and to make them all blue just remove all the red. I’m not sure about having a yellow light pattern on the car you want to use. It really depends on what the light template looks like and if it gives you the opportunity to do something like that as it might just give you options for red and blue or all blue. I have tried this before but this doesn’t work on most of the vehicles. You could play around with it tho.
