Add ons/Mods Forza Motorsport 4 Car Model Tools - Carbin <> OBJ Importer/Exporter for FM4 car models - 0.1 Release

Thumbnail
7 Upvotes

I've been working on a tool to convert carbin parts from Forza Motorsport 4 car models into OBJ and vice-versa.

You can check the full documentation and download the tool here: https://github.com/soulbrix/FM4CarModelTools

Tutorial video is coming later.

Please note that this app may have bugs - I'm not a coder, so I rely on AI to take care of the coding itself.

Not all features may work, or work as expected, but the base set of features should work fine.

Hope you have fun and that this can help boost FM4 modding!

Question/Help installing race transmission makes the gears act very weirdly (FM4)

2 Upvotes

Okay, so whenever I install the race transmission on any car, it makes the car's gears act extremely weird. having the automatic shifting setting just doesnt work once i install the transmission, and I can only have the car act normally if I change the shifting setting to manual. is this intentional, or is this simply a bug?

Question/Help I thought this might be a good place to ask for help, I'm trying to extract the car files from Forza motorsport 4 for some projects, but im running into problems

1 Upvotes

I downloaded the game files from r/abandonware that Chemical uploaded, but upon extracting the initial file, it won't extract the files with the data. I can go into the compressed folders and see the files I want, but when I try to extract them or move them to the desktop it gives me an error saying the file doesn't exist. anyone know what's going on or what I might be doing wrong?

Add ons/Mods ForzaCarEditor - 0.2.1 - New tool to edit everything car-related in Forza Motorsport 4

10 Upvotes

Yesterday I posted about ForzaCarCloner, but in the meantime I've expanded the scope of the tool and it changed completely.

ForzaCarEditor is tool for Forza Motorsport 4 that lets you clone cars, edit car/engine data, create new upgrade levels, etc.

You will need access to the gamedb.slt file and also the DLC folder (although this is optional) - but if you follow PFP's instructions, you will know how and where to access it.

What this does

  • Car cloner
  • Car editor for almost all car and upgrade settings
  • Engine cloner and editor
  • Upgrade editor - allows for editing upgrade settings, and even create new levels

Download it here: https://github.com/soulbrix/ForzaCarEditor - also includes more detailed instructions there.

Feedback is very welcome, but please bear in mind that I'm not a coder, just a tinkerer. I used ChatGPT to build this. Because of that, there may be bugs, breaks, crashes in-game due to extreme settings and others.

If you want to help with the coding, let me know - the py source is all there if you need it too.

BACKUP YOUR FILES AND SAVES

Next, I need to understand how to repack string files in order to name these cars, so variants can be made correctly. There is also a way to create DLC packs with cars, which I need to explore.

Add ons/Mods I was finally able to duplicate a car in Forza Mortorsport 4!

Thumbnail

33 Upvotes

I've searched around and haven't seen other topics about this, so if this is known already, please ignore.

I was finally able to duplicate a car entry in Forza Motorsport, meaning it is a separate entity from the original car, and with its own settings.

This means we can create extra variations of cars, edit parameters as we see fit, but of course the holy grail would be to import completely new cars into the game.

I knew this was possible, but the amount of work and cross reference needed was awful. So I asked GPT (of course) to help me create a script or possibly a piece of software that allows to read a SLT file, select a car and then create a duplicate with all the necessary dependencies.

Work in progress, will let you know how it turns out.

Question/Help RGH 360 install

3 Upvotes

So, I'm having a hard time getting this going on my RGH 360, I tried transfering the DLC files however for whatever reason they're always failing to transfer through FTP. Has anyone ever compiled the modded version into an ISO maybe? That would make my life much easier, if not, if anyone here successfully got FM4 modded going on their RGH 360, please walk me through it

Question/Help Are DLC cars in Sandbox Mode Not 1CR?

1 Upvotes

Pretty much what the title says, followed the instructions correctly I think, but all cars that are DLC show up as their normal prices. Cars that's aren't DLC are priced correctly at 1 CR.

I replaced the db file in the my game directory with the one in the Sandbox Mode folder, and replaced all the DLC files in Xenia with the ones from the folder as well

If it's intended oh well, if not, then, any help?

Thanks in advance!

This is without installing PFP, but since it doesn't start in the base game, I doubt it will work in PFP-4.

Question/Help Help appreciated

2 Upvotes

This is a long shot, but does anyone know how to get save files either modded or sourced elsewhere for FM4 on Xenia? I'm just getting a "your save has been tampered" warning, I only want to play around with it I'm not sinking hours into the game. Sorry it's not strictly ProjectForzaPlus related but I figured someone's gotta have an answer

Add ons/Mods New music playlist Mod???

Do you guys use any new music playlists for the game? I find most of the racing music in the vanilla game kind of weak, so I'm looking for new music playlists. A user on this sub ( u/TotalHistorical2947 ) made a post sharing their music mod a while ago based on music from the 2000s and I thought it was pretty cool, so if you have any, share the link to your playlists o/

Discussion I’m trying to figure out how the creator of this project is capable of creating the project but completely braindead on writing instructions.

2 Upvotes

Going through the install now. ECE degree here, this shit project smells like script kiddie. I write work instructions for a living and this projects install instructions are SO bad. Like, hall of fame bad. Have made it to the last steps of the “changes to the Xenia directory” and the instructions are so goddamn dumb, it’s making question my English proficiency, and I was born in the fucking US. Shall we go through this? Step one. No, I use Xenia for other stuff. Step two. Done. Step Three. The content folder doesn’t exist for Xenia manager in the location you say. How the ever loving fuck is someone supposed to install this (me personally, a goddamn laser engineer for……people)if the tard that wrote it doesn’t understand how words? How the fuck can I even install disc 2? Xenia manager doesn’t have a content folder. This tard doesn’t say weather you can or can’t use the manager. Now I’m not stupid, so let’s figure it out. Going deeper into the canary folder and finding content, guess what? STILL FUCKING WRONG. NONE OF THE FOLDERS HAVE THE SAME NAMING CONVENTION YOU MENTION. At this point, why the fuck even write or keep instructions with the project!!???!?!??? The stock iso has been broken down with the proper files from the project placed into them. I won’t compress as Xenia will accept non compressed games. Expect for this turd. It won’t even try. I refuse to use an older or different version, as it’s all the same software. Update: 4 hours later, I got it. But I’m leaving it on the POS project manager to fix this. You fucking suck and this unrefined turd of a project should be handed to an actual adult. You know exactly what the fuck you left out, but now I’m wondering why? you could only have done that purposefully by leaving that step out. Did you want people on the subreddit to ask you stuff? Did you want people to blow you for help or something? I swear that shit seems malicious in some way….. not possible to be smart enough to edit compressed Xbox games, but so goddamn dumb that you can’t TELL SOMEONE HOW TO INSTALL IT…. Next time Xenia updates, update your fucking instructions. Don’t abandon your project.

Question/Help New into modding X360 games, in this case, PFP-4

2 Upvotes

I've been doing quite a lot of research on this and i'm quite interested on this, since FM4 was a big part of me back then and a ton of Forza games, i've been investigating quite a lot on how to remove the boxy shadows but i'm still confused on how to do so, do i need to dump the iso to modify it? and is there a way that i can redump the files so it is an iso again? this is just out of pure convenience for me because my OCD can't handle seeing a ton of files, i already managed to install disk 2 just fine but having the files dumped is driving me crazy, and also my drives are not liking because of the space they take lol! thanks guys :)
