So when i move a lightbar to position it right on my car in zmodeler, do i have to check the L1's so that it moves with it? Also do i attach pushbar L1 to Bumper_f L1? Someone told me a long time ago they didn't matter much, but now i'm finding out that they matter more than i thought. I'm just confused on what i need to attach because i attach the L0's but usually dont even bother the L1's

yea attach those as well, on most tutorials on youtube they tell you to do that tho

If I know that i'm going to use more then one light bar, I don't check the L1's for them because when you attach the lights together at the end, you have to make copies of the L0's for L1's. If you don't make copies of your L0's to L1's then when you get far enough from the vehicle, things disappear.
