Dayum, didn't meant to cause such a diversion...
So if I understood right, they spawn by default can be prevented / change behaviour with

<extraIncludes>
<requiredExtras>

And flags like

FLAG_EXTRAS_RARE
FLAG_EXTRAS_REQUIRE

And the disabled extras be default from other vehicles seem to be hardcoded behavior?
Right... ?

Hey, Hey, Hey...
Please don't get me wrong!

I do know that there're hardcoded limitations among vehicle creation.
But I was just wondering, as it works in general with for example sheriff, police3 or similar.

I'm new to vehicle creation, most is assuming till I actually gained experience.
Yet thank the both of you so much.
But it didn't worked afterall... Sadly

Thank you anyways, stay healthy !

@HRH I don't understand, all I want is to have 2 Sirens
EXTRA_1 & EXTRA_2, togglable.
But right now, they display all the time, it's possible with the sheriff so there must be a way.
I tried adding extraIncludes & requiredExtras

Cheers everyone!

I got my hands into ZModeler including "advanced modding", how I call editing the model of a vehicle.
What so ever, I came along several problems...

I used original vehicle sheriff & sabregt and combined them.
So far, in Geometric it works butter smooth.
Yet the siren and the used extras cause problems.

• The sirens flash, without sound.
• Both extras (EXTRA_1; EXTRA_2) display at the same time, breaking what I want to achieve.

vehicles.meta
carvariations.meta

If you need any other information, let me know
Thanks in advance!

Cheers!
In case this hasn't been solved yet.
Here's how I archieved it!

• Get yourself into ZModeler
• (Optional) Isolate the COL of the Window/s
• Change Editmode to Polygon
• Select the parts u wish to be bulletproof.
• Go to Scene nodes browser => Properties
• External States => ID, set it to the desired ID.
  As reference use the Collison IDs posted by ReNNie...
• Tick following flags: Flag 3; Flag 4

If you should be successful, please let me know
Best Wishes Rach.

Welcome you "Newbie"

In order to get GTA V Models in any kind of 3D software (.obj or .fbx), you'll need the following tools:

• OpenIV
• 3ds Max
• GIMS Evo

OpenIV
Exporting the Model and Textures in openFormats

3ds Max 2017 & GIMS Evo
An GTA V Modding Suit only exists for 3ds Max 2017 under the name GIMS Evo.
You can get a student license of the newest 3ds Max. Getting 3ds Max & GIMS Evo on the other hand is a bit tricky to get.

Inside 3ds Max
If you got that far, you can import it and follow the instructions, its very easy.
Or just search up YouTube Tutorials, as they might be more informative.

Once imported, you could export it, which might work (Never tried yet).

To sum-up
There are forum threads, giving you the Modding Suit, but some work some don't or are bugged...
If you got all the stuff, feel free to DM me and I'll help you finding the right GIMS Version.

3ds Max might get tricky also, I'm unsure if there's GIMS for the newest Max version.

Best regards, Rach'
