@youngseasoon I had the same big idea as you before and after modding gta v since summer 2016 here is what I've learned.

1. Model choice
   Whether a model has LOD's or not can reduce textuere loss. For adding a few models in the game, its not a big deal but, as you heavily modify your game, you need to start using more optimized models as replacements. Also don't be afraid to choose a few low poly models with good LOD's if you don't use it that much.

2. Discipline
   When installing car mods, make sure you install 1 at a time and make backups of all .Meta files you modify. Personally, I export them in openIV and use notepad+ to edit the Meta lines before saving a copy and re-importing back into the game using OpenIV. This helps out a ton especially when there's a problem so you can go back and troubleshoot gta acting up.

3. Optimize
   Some cars in the wrong slot can create tuning issues (or amusing glitches) You'll also run into a few models that do not have custom tuning for them (the banshee is a great example) . However, with a little thinking outside the box, you can manipulate this to your advantage by modifying the carvariations.meta tuning kits to your liking (something a lot more complex but you'll understand how to do it eventually) .

I also noticed that lower traffic gamconfigs can increase stability slightly.

4. Organization
   Also i highly recommend making a table with all the car slots and what works and what does not for organization sake. Personally I have a spreadsheet document with all the cars and, what i've placed in those slots that worked (or failed).

Edit: one last thing use a mods folder in openIV. It will make your life so much easier.

For modifying every car no its impossible but you can modify most before stability is reduced to the point where the game is unplayable. (depends on luck and your system configuration)

And using a modified gameconfig would definitely help especially one that reduces traffic would help mitigate texture loss and increase stability.

I have a few other tips that I could share with you for increasing stability when you highly modify your game with custom models if you want too?

Glad you managed to fix it.

I know its possible and I've seen it done once by a user called Dekurwinator in his custom map Project North Yankton. One of the versions (wish I had more specifics but my external hard drive crashed)had a train that would go around north yankton through a connection in the LS Port terminal.

He's currently trying to release a new version and the old one has been taken down but, this proves that what you want to achieve is possible.

To my understanding, train routes in both the traintracks.xml and trains(x).dat can be modified as long as they start and end at the same value. Thus any deviation can be made to the route as long as it goes back to its normal route at some point otherwise the game will crash.

Here's his discord if you want to ask him about his Project North Yankton map https://discord.gg/JfVDcDb

Hope this info helps

@colby3920 Does this occur around just normal gameplay or while doing something like LSPDFR?

My bad forgot there were different variants and assumed that was the one you wanted. We don't have that one yet as of right now unfortunately

There's one that has been out for awhile. Its pretty good aside from leaving tire tracks of a bike I believe.

Star Wars Barc-Speeder

Hope this helps

@locotomb my bad yeah now I get the joke😂

@Willy41007 said in Saleen S281 and Mitsubishi Starion!:

@Kazzie77 @TRDOffroad97 Even the second gen is already made it to the V https://www.gta5-mods.com/vehicles/2006-saleen-s281-extreme-addon-24-tuning-parts

Wow thanks guess that model slipped under my radar.

@locotomb lol that was your mod. Anyways, you did a great job with it.
