@IDarthVaderX1 It works and will keep working forever. It uses the same structure as official DLC folders and those haven't changed.

@Reyser really ok that's ok thanks. :)

Does this work with any type of gun or only assault rifles? (I mean could I install a handgun or pistol mod for this?)

What does vehiclemods folder do? What should I do if each car has their own .meta?

@Reyser

i am using Base folder to combine multiple vehicles into one dlc.rpf

i have created a new folder named as "AddonCars1" (as my previous folder "AddonCars" crossed 1GB) and put 3 cars into into it already (all 3 working) boss302, evo9, evo10.
Problem started when in tried to add combined dlc from vans123 (https://www.gta5-mods.com/vehicles/2017-ford-raptor-hq-rigged-suspension-multi-dirt-animated-engine-tuning) into this setup.

This vehicles dlc has 3-4 vehicles clubbed into it (laferrari, mustangbkit, raptor2017, aventadors)
i extracted all required vehicle files .yft and .ytd and vehicle_mods.rpf files along with vehicles.meta, handling.meta, carvariation.meta

put all things into place like vehicle file into vehicle folder, vehicle mods to vehicle mods folder. then copied required lines from 3 text files to base folder respective files.

after that game starts normally, but when i try to spawn cars (newly added) it says "invalid model" but surprisingly some of my previously installed cars also stopped spawning (invalid Model) after this (boss302, evo9) but evo10 worked.

mods i am using.

Gta v redux (latest) (for better vehicles handling)
on that natural vision remastered.

NO ENB!!

asi plugins..
heap and packfile limit,
custom gameconfig
Script
Turn indicator

Thanks in Advance.

@psteharia Probably your problem is that there's a typo in any of the meta files. If some of the dlc cars spawn but any of the latest ones doesn't then it's definitely an error in any of the meta files.
To know where can be the problem, make sure to spawn all the vehicles in the same order as you put them in the meta files and if any of them doesn't spawn then you'd know from which meta lines you have to start looking at to find the error.

@Reyser
Thanks mate, surely i will do check them in order. But i am confused that cars which were installed previously started showing invalid model but not all of them. As previously i had boss302, evo9, evo10. After merging more cars only evo10 was working, boss302 & evo9 didn't worked(invalid model). No file altered in between. But still try to spawn them in order today.

Thanks again.

@psteharia I'm not sure if it will be your problem but still is the most probable. Also, it's possible that some minor add-on vehicle mods are not compatible to be used in dlc packs. I've had that problem with a DyC (author) Porsche car a while ago (which I don't use anymore) which strangely was only working if put in a dlc folder alone but not in any of my packs.

how to use this mod for replace mod vehicle ? just drag and drop the yft and ytd mod to base folder ?

@Reyser For some vehicles we have to add lines in extratitleupdatedata. Then how we are gonna combine those dlc vehicles with another one

@Labibmods No. You'll never need to use "extratitleupdatedata" because this file is used by Rockstar Games when they update existing files from x64/dlcpacks to update.rpf/dlc_patch. Vehicle mods never get updated using the Rockstar Games way so you don't have to use such file.

@Reyser OK thanks nice mod btw

thank you i'm able to create an working add on vehicle

but do you have a video on how to make the add on vehicle we created into a replace vehicle ? i tried but i couldn't understand the steps

lol i wish i had found this much sooner ffs =P

@Reyser Upon following your tutorial on the forums, I can't use the tuning parts for the Ford GT (or any other car I've added). They show up on the menu in LSC (so it shouldn't be an ID issue), but the actual part isn't visible on the car (like the replaced part turns invisible as if the file is incorrectly referenced or named). Did I mess something up or is that just how things are?

@DOC281 If you renamed the tuning files, you also have to rename them in the **carcols.meta** file info.
In the carcols.meta file you'll have to find "<modelName>" & "<modShopLabel>" tags and rename them with the respective tuning files names.
For example, if you renamed a tuning part from "fgt_bump1" (invented name) to "fgt_bumper1" then you'll have to go to the carcols.meta file and do the same:

Find:
<modelName>fgt_bump1</modelName>
<modShopLabel>fgt_bump1</modShopLabel>

we would rename them to:

<modelName>fgt_bumper1</modelName>
<modShopLabel>fgt_bumper1</modShopLabel>

@badmanvegeta Sorry I don't have a video showing how to convert and Add-On into a replace.

Thanks I figured it out. Solid mod though.

( unable to open archive: archive is corrupted. RPF_INVALID_ENTRY_3: invalid archive entry size )
I added some outfit for SP and being tired for this message. any solution for that.. ?

Following the base folder for Add-On Ranged Weapons, I happened to notice that launching up the game, and trying to spawn in my Add-On via trainer does nothing. Is there something i am missing?

Thank you very much for this beautiful package! <3
