You can do it in Zmodeler 3
Choose the light you want to color it and open materials editor
In scene selection you'll see the texture\material assigned to it
Just copy it and apply the new material on the light and then double click the material and change color to whatever you want
Export it and test it in game

Unfortunately, he does not reply but I'll keep contacting him

I have an idea what if i chosen one of those midi's included in mod and replaced every othe midi with so all of them will be the same sound and horn it in game 🤔
If that worked then the game has it's own midi format cause he used GTA IV vanilla midi's
Btw is it possible to the same thing but using .wav sounds? I mean if we forgot about midi and tried to do the same thing but using .wav

@a63nt-5m1th
yes please try if it possible to use .wav instead of .midi it will be better

@a63nt-5m1th
ThanksAlot !!
I'll try me best to find a way to get any edited '.midi' files to play in-game and i'll tell you
thanks !

try this mod after you select MP character from menyoo, it'll allow you to use custom hashs for your MP character and gives u abilities to use phone or buy stuff...
example
i like mp female character i put it using menyoo then i use character swap to replace it with franklin

and this is my addon that i want to make sounds for
https://www.gta5-mods.com/vehicles/2014-hyundai-porterii-add-on-vehfuncsv-sounds

"Whatever vehicle sound you want to create/edit, you'll be able to get the basic process from those tuts, but let me know what you mean by "ambient sound" if you don't mean the engine sound?"

i mean like ice cream truck sounds when you press "E" to horn it starts playing music

How i can make custom ambient sound for an addon car ?
I've downloaded addon car ans opened it's rpf but I didn't understand what is that...
So if anyone can help me to learn how to make ambient sound I'll be thankful
