Hello,
So later on I tried installing siren packs to FiveM, but it didn’t work.
I watched a lot of videos, all of those people are installing them in main GTA:V files,
but when I did it it didn’t work. That’s when I understood you need to install stuff to FiveM.app
I searched for tutorials and I didn’t find any. I tried installing it myself, but that’s how I just fucked
my FiveM.
If you know how to install it to FiveM in FiveM.app not GTA:V files, it would be grateful if you could write it here or write a tutorial link if there is one.
Unfortunately Siren Packs cannot be done Server side (unless FiveM has made it possible recently). You will have to have your clients and yourself do such modifications client side.
The short version is install whatever sounds you need (sirens in this case) into your resident.rpf. Then use archivefix to re-encrypt so it will work w/ fivem.
