Is it possible that, if you are adding cars with no visual mods, just stat mods (so basically the default mods in Los Santos)... do you need to add a modkit for every car you add in? Or, can you define one modkit with no visual mods, and have all of your added-in cars use that? Why or why not?

I know it sounds like a stupid question but I don't know why the game wouldn't let you assign a modkit to multiple vehicles, if there are no actual parts (no .ytds or .ytfs)...

I ask because I'm adding in about 60 realistic cars, and want to give them all close to real world stats, f/r/awd, weight, brake bias and fuel tank capacity... this is a job enough. So I won't have any tuneable parts for now. But I do want each car to be able to go to Los Santos and get the standard upgrades to engine, brake, suspension, etc. So in this case would the above idea work? Do you get what I'm asking?

I should add that I'm editing the popgroups.ymt to only spawn my cars, in different areas such as poor, mid, and rich. So theoretically all the vanilla cars would be replaced with mine, with a few exceptions...

Greetings,

I tried searching around here but haven't seen this exact idea. I know a bit of C++ and C#, but I have no experience coding for GTAV.

I have an idea for a tool/mod and I would like to know if someone can create this.

Every time the game updates, we have to update ScriptHook/DotNet and possibly RAGE, etc. But then we also have to delete our mods/update/update.rpf and replace it with the new one. Of course, our 'original' (modded) update.rpf may have countless modifications done to it, affecting one or more files (materials.dat, for example).

My question/request/suggestion is, can we make a tool that will backup the modifications done to your update.rpf automatically? This way, you can run the tool, it will extract the files you've modified (complete with their directory structure) and you can store them for a minute. Then you copy over the newest update.rpf, and you can either drop your 'old' modded files into it, or you can compare the two files in question and compare the changes.

Example: I have a mod that affects the puddle size that edits materials.dat and also get a grip mod that affects materials.dat. I had to manually combine the two, so it would be great if we could have a tool that would extract the modified file/folder structure /common/data/materials/materials.dat and then we could replace it in after an update.

I don't know anything about OpenIV or how it reads .rpf files, but I know that when we modify a file or replace a file in the .rpf, it loses it's "encrypted" flag/status. So maybe a simple approach could be, have the program loop through the rpf's directories, and when it encounters a file that isn't encrypted, write out the directory and extract the file, then continue looping.

Is this a good idea or a bad idea for managing this situation where multiple mods affect one or more files? Does this sound like it would make it easier for managing re-applying your mods after an update? Is this possible?

Thanks for reading.

Ok I'll try to change the id to something like 913 and see if that works. The number I type in is the number it assigns, correct? As in, it's not hashed or converted to an 8-bit value or anything weird, correct? And just to be certain, the value that is in the carcols.meta <kitname><idvalue="913" />...is the value I am changing, correct? If the spawn addon cars trainer/mod reports a different id, is that normal? Sorry for so many questions I just really can't understand why this particular part isn't working when everything seems to be linked up and set up properly. I am using a vanilla gameconfig.xml, do you think that would have an impact? I thought it shouldn't if I'm only adding one or two addon cars to begin with...

So what I understand from your reply is, don't bother adding in mods like Get a Grip, etc. to my /abc1/ dlc because the files in mods/update.rpf will take precedence no matter what. This is true even with the "<order value="9" />" tag in the setup2.xml? Like even if I put my dlc as the highest value?

Thank you again for clarifying!!

@Reyser
Roger that, I will try and keep it the way it is, since it is working now, why break a good thing?
I tried several different methods to make the tuning parts work for the Lambo Reventon, but I've had zero luck with getting the names for the side skirts and spoilers to show up. I've tried rehashing, I've tried changing the modkit id (it shows up as 113 in the trainer I use, but was set to 175 in the meta files), I've tried using generic MNU_SKIRT as the <identifier> in the cols.meta... I'm at my wits' end as far as that goes.

I do have another question though. Using your mod, can I add other mods into it, and when do I need to add to content.xml?

For example, there is a mod that is called Get A Grip that improves traction and handling. It does so by editing the materials.dat file. If I copy the layout/structure from this mod, (update/update.rpf/common/data/materials/materials.dat) into my mod (mods\update\x64\dlcpacks\abc1\dlc.rpf\common\data\materials\materials.dat) will it work? Do I need to 'declare' it in the content.xml? If so, what 'type' would it be? Sorry to be general, but I think you get what I'm saying? I'm at work I can be more specific when I get home...

@Reyser
I'll stick with your guide as I'd rather keep it as simple as possible. That being said, I did add another Add-on vehicle last night, the Porsche GT3 it is gorgeous. Everything works like a charm except I had to go into vehicles.meta and rename it (was being called the pfister something or other). I then had to hash the make and model, and add them to the global. Once I did that, it's perfect. I've one last thing to try with the tuning parts for the Lambo Reventon and that's to try and use the generic tuning parts names in the "identifier" section in one of the metas.

Anyway one question I did run in to with the Porsche - it included a file /data/ai/vehiclelayouts.meta. I included this file in the content.xml and made a place for it in my base folder (I copied the structure from the download so it's /abc1/dlc.rpf/data/ai/vehiclelayouts.meta). Is this file necessary to duplicate, and what exactly does it do? Will the game crash or malfunction if I were to leave it out?

Thanks again for all your help!

@Reyser
Thanks!

I did try to redo the hashes using OpenIV's hash generator. The make "Lamborghini" was the same, as was the model "Reventon", but the hex codes for the parts did change. Unfortunately, they still didn't show up in Los Santos menus. I tried the Case Sensitive option and all the hex codes changed and none of them showed up.

So I kept reading some of your questions and eventually I used the
"tuningpartfilename = Part Name In Shop"
formula, and everything shows up now except the side skirts and the spoilers. I'm not sure why. I got the list of vanilla tuner parts names and maybe I'll try and sub a generic one in place of those missing ones. In any case, I do have a question:

Following your guide, I then stumbled upon I'm not Mental's guide: https://www.imnotmental.com/guide/add-on-vehicles-tutorial/ he has some extra steps, using the content unlocks.meta and shop_vehicle.meta files... is there a reason he tells us to edit these but your guide doesn't? Which is more better/preferred/more stable?

@Reyser
I'm not worried about uninstalling and having remainders in there at the moment - I'm planning to keep it small and do a 'proof of concept' so I can really get an idea of how it works. That being said, the parts are renamed according to car (i.e. reventon_boot_1.yft) so removing them later if I ditch the car shouldn't be a hassle I don't think.

I opened up the gxt2 file and I see:

0x05D2A215 = Painted splitter
0x2DCA9CE0 = Painted spoiler
0x3B6A381F = Carbon fiber spoiler
0x9FEE6E13 = Carbon fiber bonnet
0x782AA152 = Carbon fiber skirts
0x6439658D = Sport carbon fiber boot
0xABC889D5 = Painted skirts
0xAC6B8829 = Lamborghini
0xC7D5F5FB = Reventon
0xFC3C8EE9 = Carbon fiber splitter

Hash of the car is correct since it shows in the add-on spawn menu and in Los Santos. The titles for Painted splitter and Carbon fiber splitter also show, so their hashes must be correct also. So I guess I just have to assume the rest are incorrect and correct them. Does that sound like I'm on the right track? I will look to see where that was mentioned. If I get everything all working together I'll post back and also 5 star this mod. Thank you for your hard work and also your support!

@Reyser
Thank you very much for such a speedy reply. Regarding the tuning parts, using your method, I can continue to add all tuning parts from all replace cars I find into that one tuning_mods.rpf file, as long as they have different names, correct?

As far as the missing parts names, I wonder if anyone else has added this particular Lambo Reventon and can vouch that their tuning parts names pop up. I will check the comments page on that download.

I am not at home right now I'm at work, but I do not believe he forgot to include the hashes for the missing parts. Perhaps they are incorrect, though? I saw in one of these tutorials how to calculate, it was based off of the Car ID, right? Is that in one of your tutorials?

Thanks again, and this is definitely a 5-star rating once I get it going.

For "<filesToEnable>" section:

I think I followed all instructions very well. I used the Vehicles DLC Folder #2, which has the "tuning_mods.rpf" since I know some of the cars I want to add in have tuning parts. For users like me, shouldn't the above instructions reference "vehiclemods/tuning_mods.rpf" since that's what's in Vehicle DLC Folder #2?

I ask because I was able to add in Scrat's Lambo Reventon but at first, when I went to spawn it through a mod, it was listed under NULL, and none of the proper titles came up for it (for instance, when I entered the car, it just said ", Super", and none of the parts in Los Santos Customs had names, they just had blank spaces and the price - although they do preview on the car).

So I added the /x64/data/lang/americandlc/global.gxt2 from the Reventon's rpf to my base folder's dlc.rpf (my base folder is named abc1, so I added the file as "mods\update\x64\dlcpacks\abc1\dlc.rpf\x64\data\lang\americandlc.rpf\global.gxt2").

Now, it has the proper make and model info in the spawner mod, and when I enter the car, the make and model come up. Yay! But when I go to Los Santos Customs, only some of the parts names come up. For example, now the Bumper names come up, but not the spoliers or skirts.

Any idea what may be going wrong? This is the first and only car I've added in.

Pics: https://pasteboard.co/I56Wec1.jpg after adding the global file, the name comes up, as well as now the bumper names: https://pasteboard.co/I574A25.jpg but for some reason, missing names for skirts: https://pasteboard.co/I575im6.jpg and other parts.
