@Kiddabob When in ZModeler you have to select all of the broken lights individually in vertex mode. Once you have selected all of the vertices of the light you need to go into the properties tab next to the structure tab. In there, there should be a row that says ID 0.

You need to set the ID to match the following for each light individually:
left headlight (headlight_l) = 1
right headlight (headlight_r) = 2
left taillight (taillight_l) = 3
right taillight (taillight_l) = 4
front left indicator (indicator_lf) = 5
front right indicator (indicator_lr) = 6
rear left indicator (indicator_lr) = 7
rear right indicator (indicator_rr) = 8
left brakelight (brakelight_l) = 9
right brakelight (brakelight_r) = 10
middle brakelight (brakelight_m) = 11
left reverse light (reversinglight_l) = 12
right reverse light (reversinglight_r) = 13
extra light 1 (extralight_1) = 14
extra light 2 (extralight_2) = 15

@Faysal Is it possible for you to put up a tutorial as to how to fix the lights, I can't find what you are saying in ZModeler. The polygons for the lights are lit up at all times but the light sources work correctly and only come on when it is night or they are turned on.

If you create a misc object inside of the [wheel_lf] and each of the others then you can apply whatever material you wish and have it emissive. They do not pop so if you are going to use this technique then the wheels will need to be bulletproof. Also the each of the miscs will have to be aligned to each wheel individually.

Is It possible to add an emissive texture to a wheel in ZModeler3?

I found a temporary solution that uses the vehicle_badges material type, for just the windscreen and that way it doesn't get tinted. I do need to fix an issue with the window having a blocky shine, but I assume it is just a texture that I need to choose.

@Viccracenvy It is already set to that and it still isn't working

Can anybody let me know how to stop the windscreen from tinting? I have looked at how a standard GTA V model has its materials set up that are linked to the windows. From what I can tell I am doing it correctly but the windows are tinted when choosing the window tint options in LSC.

It no longer matters as I have figured out how to use the Deluxo's flight for my vehicle and that works very well and there are no sounds to deal with. That begin said if anyone else needs this information feel free to use this post as the discussion about it

@InfiniteQuestion I am adding a custom vehicle into the game as a mod-DLC and it uses a helicopter as its vehicle type, but it uses thrust like a hydra so it needs to fly like that but without the sound.

I am also in search of an answer to this. If anyone knows that would be very helpful, Thanks
