Vehicle parts and shaders

[Dzsozi (h03)]

Hello! I was browsing around and I found an MTA server called NFS:SA MTA, which is obviously a Need For Speed themed gamemode for MTA:SA. The developers of this server made a really nice job with this server and it's resources, but I'm interested in one or two things about some of their scripts, I have no idea how they could make it. So first of all, how is this possible to add tuning parts to a non-tunable vehicle? Like the bumper of a tuned elegy or sultan to a nebula or something? I know that some of the tuning parts are objects, so I can create them via createObject and attach them to the vehicle. But how can I count the position of the tuning part? Or do I have to use a table for every tuning part's position on every vehicle I would like to make tunable, and also, do I have to make a custom tuning shop to apply these tuning parts? How can I save and load a vehicle if it has tuning parts?

Example picture:

 

If I see it right, it is the primo. How is this possible to make a bumper, skirts and etc for that vehicle and attach them? If I'm not mistaken, it is possible to put every spoiler on every vehicle in MTA, how can I do that with other tuning parts as well?

 

The second question I have: how can I make a vinyl for a vehicle and then apply it anywhere I would like to on the car? Example picture:

Again, if I'm not mistaken, devGaming also made it possible, they have tons of (around 500-1000) custom vinyls as png images and it is possible to apply it anywhere on the car.

Example of the devGaming tuning/vinyl system:

EDIT: picture one, meant to write cadrona, not primo

As for the first one you create an object, attach it and use setElementAttachedOffsets to change its position.

(Edit: To get its position use getElementAttachedOffsets)

As for the vinyls that is something I'm trying to figure out myself; what I've tried just causes it to wrap around the whole vehicle.

Pretty sure the vehicles need to have modded UV wraps to have no overlapping parts.

So I guess I have to use tables for that with the object, and the positions of the object for the vehicle. So a lots of data should be given.

What does that mean? How is this possible to do that and if I did that how should I do the scripting part?

[Addlibs]

I am by no means a modder and I do not know how to edit cars but I do know that the server from the last screenshot on the initial post, devGaming, did have to mod their vehicles' DFFs to get UVs unwrapped. The scripted part is simply drawing an image on a 2D map as you can see on on the red image on the right of the screenshot.

I was wondering at first if that was the case. And now that I look the vehicles lack dirt; meaning that is indeed what they did.

No they are not.

[Dzsozi (h03)]

Well, actually that could be the case for the bumpers and skirts, since they look so smooth and correctly fitting, but that would involve lots of modelling I guess, since you have to make and add them in, for example 3ds max as a part of the vehicle.

Adding variants requires modifying your DFF by adding a part of the model you wish to be a variant and naming it extra1, extra2, extra3, extra4 or extra5 then setting it's parent to the chassis_dummy this tells GTA it has variant information and after this your variant will work in MTA.

But I think there is an easier way than this. I'm not sure.

[Captain Cody]

Oh sorry I thought you were speaking of the shaders; for the parts yes custom variants may be the case.

 is just use Visible set Component to activate and deactivate parts of vehicles such as bumper and etc.
