This text will gave you instructions how to add your custom vehicle to traffic, either on popgroups.ymt and vehiclemodelsets.meta.

Reasons:
I will no longer release updates for this mod, because I will be busy when I come back from holiday. But I will still respond to comments & feedbacks in the mod page.

=== POPGROUPS.YMT ===

On this text, we'll be using ranstar74's BMW M5 F10 mod as the sample vehicle, which had its internal name 'm5'.

The line format is written as follows in popgroups.ymt.
		                		<Item><Name>(vehiclename)</Name><Variations type="NULL"/></Item>

As ranstar74's BMW M5 F10 had m5 as its internal name, so it will be written like this.
		                		<Item><Name>m5</Name><Variations type="NULL"/></Item>

As Game68240's Nissan Altima Sedan had nisaltima as its internal name, so it will be written like this.

The data above is the data for the pre-modded red and yellow Banshee that I also made for my archived mod, More pre-modified vehicles. It was also now come by default with this mod. Based on the data, other fitted aftermarket modifications were: Drift Wing, Carbon Hood, Large Exhaust, Street Suspension, Limo Window Tint and light blue Organic Type.0 rims.

Now let's move forward if you want to create your personal pre-modded vehicles.

One of the pre-modded vehicles line should look like this:

* There was also a full black tint in GTA Online which had the WindowTint value '3', but it doesn't work here.

- (Color) stands for the vehicle color value. For all color list, visit this url: http://imgur.com/a/F4Ptk (0 stands for black)
- (Value) stands for the mod type. -1 means no mods, 0 means the first item, 1 means the second item, and so on.
- To know the list of mods that can be applied to vehicles, use OpenIV to browse these directory: x64i.rpf\levels\gta5\vehiclemods (for original vehicles) and (dlcname)\x64\levels\gta5\(dlcname)\vehiclemods (for DLC vehicles and add-on cars).
- Special mod parts in LSC and parts that can be fitted only in Benny's Original Motor Works (with modtype VMT_9, VMT_27, VMT_28, etc.) such as Tornado's fender ornaments, sunstrips/doors on Sultan RS, will not work here.
- You can add up to maximum of 6 pre-modded vehicles. If you add more than 6, the game will glitch out.

That's all...
