Don't know if possible or how difficult but would there be a way to have multiple dirt textures in vehshare that load under different circumstances?
I saw https://www.gta5-mods.com/paintjobs/raindrop-texture-beta and refrained from downloading because it replaces the normal Dirt texture.
A script that made it so that texture loaded when it rained or something would, I think, be great.
Anyway if anyone would look into it that would be great. 
@ITribute Either replace the car the mod was supposed to or edit the sentinel carcols etc. I'm not very familiar with all the files that need to be edited for tuning parts but i recommend just replacing the specified vehicle.
@enjoythekilling If you want an easy to install mod that improves some features of the game check out https://www.gta5-mods.com/misc/fine-tuned-felony-response . it comes with a OIV package for easy install. all mods included:
Crime & Police Rebalance and Enhancement by BobJaneTMart
Euphoria Ragdoll Overall by MiGGoust
Realism Dispatch Enhanced by Dilapitated and mkeezay30
Refined Weapons and Gunplay by State_of_Mind
Streets of Rage Brawling by RS Beats
World of Variety by Cass
If you want a handling mod I also recommend https://www.gta5-mods.com/vehicles/vehicle-handling-v which also has OIV package install.
Don't assume it is an easy job. Its not a case of transferring files. If you have a legitimate copy of the game the files are already there. Its a long matter of unlocking them for use in SP and creating brand new scripts. (I assume)
Are you sure you are using the correct model name to spawn them. For example the aventador spawn name is polaventa
Since i've never actually done any modding for GTA yet I have little to no experience. Dont expect this soon. Maybe within the next month if I dont get bored and give up
If any experienced modders want to have a go converting this model its here : http://gamemodels.ru/files/file/928-2003-nissan-skyline-350gt-mkxi-v35/
So after downloading the mod quickly i noticed the author only made edits to the model. Because the coquette usually has alot of tuning parts some of them haven't been replaced so they are still the default. However I don't imagine you are seeing many customised coquettes in singleplayer and i recommend not using the mod in multiplayer as it can result in you getting banned or put in the cheater pool.
These are "Coronas"
I recommend https://www.gta5-mods.com/paintjobs/corona-begone
This will remove the corona on all vehicles.
@Calligan If you have done everything including editing dlclists and extratitleblahblahblah then you can spawn it by its model name. Usually this will be the name of the dlc folder but if that does not work go on open IV. go into the dlc folder and find the .ytf and .ytd files in there. The name of those is what you will need to spawn it. I use this trainer : https://www.gta5-mods.com/scripts/enhanced-native-trainer and in the car spawn menu there is a "SPAWN BY NAME" section where you can input it. I don't know what its like for other trainers.
@adamjensen2030 You will need zmodeler2 if converting other mods from gta 4 or gta SA
Top speed and acceleration can be altered by the handling.meta file. If you don't want to edit it yourself as some of the data can be confusing. you can copy the handling data from another vehicle.
There are many mods that have aimed to improve the acceleration and top speed of all the vehicles in the game.
Check out https://www.gta5-mods.com/vehicles/realistic-topspeed-mod for better acceleration and top speed or https://www.gta5-mods.com/vehicles/vehicle-handling-v for a more realistic driving experience. (includes revised top speed and acceleration)
Some cars can be installed as an ADD-ON and this will prevent the car from spawning in traffic (unless you alter popgroups) but requires a trainer to spawn it by name.
I found you an M3 GTR that can be installed as an addon. https://www.gta5-mods.com/vehicles/bmw-m3-e46-gtr-addon
Make sure you install properly by reading the Readme and if you still dont understand check out this tutorial here
Also make sure you download and install an up-to-date gameconfig.xml file if you plan on installing multiple add-ons
I guess its just common to see modders go for classics or modern but none of the inbetween
The guy in the house across my street owns a CLK 500 AMG (Or at least one with an AMG exhaust conversion) and sounds like a beast like any other AMG.
Anyway since after a quick search I found a CLK55 AMG model from forza 4 i thought someone could have a go at converting it. (If its not too much trouble)
I would try myself but all my efforts trying to do anything to gta so far have come to a complete dead end.

Thanks, Joe
The whole dummy thing is complete mind-fuck to me. Thanks for your response. I'll be looking out for your guide and in the mean time I think i'll stick to just playing.
So I want to start by saying I have no previous experience modding GTA V or any GTA for that matter. However recently i've really craved some certain vehicles to mess around with and thought i'd have a go at trying myself.
I downloaded a model from Forza 4 from gamemodels.ru and converted various parts to .obj files with Forza studio.
My first problem arose when I started to gander in Zmodeler3. From my limited understanding (which could be completely wrong) i believe each part needs to be named a certain way and have a specified ID. After looking around I found a bunch of tutorials about converting to GTA IV or GTA SA but none are English and are super hard to follow. From just watching the video I thought I should start by seperating the doors from the body. When I started trying I realised I cant seem to find out how to select anything in Zmodeler (I may just be absolutely brain-dead) and furthermore I have no knowledge of how to use and apply textures in Zmodeler and I keep getting errors.
Anyway, at this point i'm pretty much on the edge of quitting this little project because I have little determination.
I would greatly appreciate some guidance and if anyone could link to a full English written tutorial I would be thankful.
Thank you, Joe
