Welcome to GTA5-Mods.com

Anyone having issues understanding the install instructions or getting a crash loading the game once installed, have a read of this post:
https://forums.gta5-mods.com/topic/40376/overhauled-trains-installation-help/2

Basically, for crashing, install the 'trains.xml', 'traintracks.xml' and 'trains1.dat' files into the 'gta5' folder in 'update.rpf' instead:

Install those '.xml/.dat' files to here:
...\Grand Theft Auto V\mods\update\update.rpf\common\data\levels\gta5\

@megaz0id
Nice. Cheers.

@megaz0id
Any chance of having a way to save the number plate as well when you save a custom vehicle?
So it would automatically load VStancer settings when entering the vehicle etc. Thanks

If anyone has trouble getting any of these to work after following the instructions of people above, refer to this post:

You can find info in this thread:

Here is the 'dlcsmuggler_sounds.dat54.rel.xml' from the last post in that thread, but converted from '.rel.xml' back to '.rel' (drag & drop in OpenIV & use it to replace the original. Make backup first, just in case):

301 vehicles total. That would only take ~25mins work (at 5 secs per rename) to rename at most (or use TextPad etc & do an incremental rename (rename to gtaiv1, gtaiv2...etc) using wildcards to do it in seconds). Either way will stop the sounds being applied to vanilla vehicles.
Next, do like I said & track from the vehicle name to the '<Engine>' line hash to '<ExhaustHigh>' hash etc (any EngineLow/EngineHigh/ExhaustLow/ExhaustHigh hash will do) & then into 'ivvehsfx_sounds.dat54.rel.xml' to find what audio file is used ('ep1_pickup_1', 'ep2_muscle_car' etc) & then track back & rename them that way.
Alternatively, & even quicker, just start in the 'ivvehsfx_sounds.dat54.rel.xml' file & use a hash from the '<Name>' line in a '<Item type="SimpleSound">' section (141 total) of each different vehicle sound ('ep2_599_supercar', 'ep2_gt_supercar' etc) (19 total) to track back into the 'ivvehsfx_game.dat151.rel.xml' & find & rename (incrementally/differently etc) all vehicles that use it.

@MrFinger
Awesome work. Nice approach removing the '<EngineGranular' parts. I never noticed/thought about investigating engine sounds in that way. Good job :)

@mrwallace888
You can do that dead easily yourself. Just export the 'ivvehsfx_game.dat151.rel' to XML using CodeWalker & then edit the '<Name>' line in each '<Item type="Vehicle"' section to anything else. Name them 'gtaiv1', 'gtaiv2', 'gtaiv3'... etc if you want (easiest way). Any non-vanilla vehicle names will do (they all need to be different obvs).
Alternatively, track using the '<Engine>' line hash to '<ExhaustHigh>' hash etc & then to 'ivvehsfx_sounds.dat54.rel' to find what audio is used & name them ordered that way instead etc. Whatever you name them, you can then use those names in any vehicle's 'vehicles.meta' '<audioNameHash>' line.

@RisingHornet
If it's the blue horizontal flare (animorphic flare) you are talking about, make the 'flare_animorphic' texture in 'graphics.ytd' completely black to remove them.

@LightningJet357
Looking for the same rear lights as on the Challenger in pic#3 (dark one, on right).
Is that a different car? (rear lights don't look exactly like that on this one etc). Thanks
