EDIT::
this issue is related to an issue with vehicle layouts meta file loader native
has to run in a separate _resource.lua
seems like if a _resource uses a Native data_file that has a location, the same _resource can not also send a data_file to a different location.
see below for more details
what the fuck?
this has nothing to do with ‘natives’ or directories or ‘files being put places’, you need to load the vehiclelayouts file in the right order, if you load it in the wrong order it of course won’t work since it doesn’t exist when the game asks for it.
So what you’re trying to say is that, instead of taking the file out of the AI folder, I should drag the entire folder?
I am only specifically talking about using this in a _resource.lua on an fxserver
in said lua, the file is most certainly in the right order.
I believe the issue may be this:
A) the RHD layout file being used for most RHD is the same file copy pasted among everyone, and its written for a 4 door 4 seat vehicle. (makes problems with cars like the rx7)
C) the file has to be loaded after all the vehicles load
so my next test was going to be:
on a Subaru wrx sti that was an add-on and RHD from 5mods
remove the vehiclelayouts.meta and references to it from the cars _resource.lua
add it to a new _resource.lua using the 777 manifest version
edit out that line 4
start the new resource after all vehicles
ok finally got to test it and yeh figured it out.
good news! the NATIVE WORKS! Kinda not as expected
AGAIN, THIS IS ONLY RELEVANT TO RUNNING ON FXSERVER:
primary requirement: all vehiclelayouts.meta for all vehicles must be run in a separate resource
and that resource MUST be loaded AFTER all vehicles are loaded in the server start order.
example of that resource:
resource_manifest_version ‘44febabe-d386-4d18-afbe-5e627f4af937’
files {
'vehiclelayouts.meta',
'evo6/vehiclelayouts.meta',
'jzx100/vehiclelayouts.meta'
}
data_file 'VEHICLE_LAYOUTS_FILE' 'vehiclelayouts.meta'
data_file 'VEHICLE_LAYOUTS_FILE' 'evo6/vehiclelayouts.meta'
data_file 'VEHICLE_LAYOUTS_FILE' 'jzx100/vehiclelayouts.meta'
I can confirm its working on my server with 4 different vehicles that are all RHD addon vehicles, 2 of them are sharing the same layouts.meta, and the other 2 have their own layouts meta (you can tell if they are unique if you check the name of the layout in the vehicles.meta file or in the layouts.meta itself)
those working vehicles are:
as for the RX7 FD pandem, it appears to be trying to share the same layout as the wrx and the civic, but it may be a modified version of the original that the rx7 creator didnt change the name when he modified it. ill have to do more testing on that car specifically to figure out whats wrong for sure, but it still crashes.
also, im not sure if it will make a difference with other vehicles, but with all these vehicles I am using the newest resource manifest version number 44febabe-d386-4d18-afbe-5e627f4af937
anyway hope this helps somebody
drive fast and take chances 
ok final update, got it all working with vehicles installed in a single resource, layouts and vehicle_names.lua in a second resource.
EVEN THE RX7 WORKS NOW with the shared LAYOUT_LOW_RHD
vehicles resource example:
resource_manifest_version '44febabe-d386-4d18-afbe-5e627f4af937'
files {
--jzx100
'cars/jzx100/vehicles.meta',

data_file 'VEHICLE_METADATA_FILE' 'cars/FD/vehicles.meta'
data_file 'CARCOLS_FILE' 'cars/FD/carcols.meta'
data_file 'VEHICLE_VARIATION_FILE' 'cars/FD/carvariations.meta'
and then the vehicle layouts resource example:
resource_manifest_version '44febabe-d386-4d18-afbe-5e627f4af937'
files {
'vehiclelayouts.meta',
'evo6/vehiclelayouts.meta',
'jzx100/vehiclelayouts.meta'
}
data_file 'VEHICLE_LAYOUTS_FILE' 'vehiclelayouts.meta'
data_file 'VEHICLE_LAYOUTS_FILE' 'evo6/vehiclelayouts.meta'
data_file 'VEHICLE_LAYOUTS_FILE' 'jzx100/vehiclelayouts.meta'
client_script {
'vehicle_names.lua' -- Not Required, but you might as well add the cars to it (USE GAMENAME not ModelName)
}
that should do it. just make sure the layouts resource starts directly after the vehicles resource. 
@N3ON1: also now have got both of those vehicles working with same method / same asset. (the Fairlady z and brians r34 working great)
I dare say any vehicle should work now.
Awesome work. Will have to test them out later as it is late at night.
So i have had RHD drive cars work no issue. Im trying the chaser, trying to do a separate layouts file for the jzx100 but the car spawns, doesn’t put me in it, and if i try to get it it crashed me.
yeah its RHD issues . but i dont get what @Radbug said . my brain stop working or please make a video how to fixed it TIA
I found a new issue (maybe I am just a tardo at doing this)
I can get the vehicle to spawn in and everything, I have moved the vehiclelayouts.txt file into its own .lua file. But when I “F” to get into the vehicle, my game crashes and gives me the “moon-island-uniform” crash.
If someone were to make a video on how to fix this, please link it here >.<
Just make sure your vehicles load with the resource formats I posted above and it should work. 2 separate resources. One is the vehicles, the other is the layouts. make sure the layouts resource loads after the vehicles resource
so one folder two resource ?
how do you put 2 resource files in one folder?
it’s easy if he make video for us ;(
you cant. must be in separate folders.
You can you just need to follow the tutorial that are out there on how to combine resources.
Hey Rad, Im having a rough time figuring this stuff out, and im curious if its possible for you to share the files as you have them working for the cars? I’m trying to get the Rx7 working specifically but I’m quite lost
those are the only files. they are just a __resource.lua
the vehicles addon should be in a folder (lets call it VehiclePack)
so inside VehiclePack folder should be:
put all the vehicles model/texture files (.ymt etc ) in the ‘stream’ folder
put all the .meta files (vehicle.meta handling.meta carcols.meta etc) EXCEPT the vehicleslayouts.meta in the main folder (VehiclesPack) not in the stream folder
thein for the second addon you make a new folder outside of the vehiclespack folder (completely separate) lets call it ‘VehicleLayouts’
in that folder should be :
finally in your server cfg add:
start VehiclePack
start VehicleLayouts
in that order, preferably earlier in the cfg rather than later
This is what i was looking for, I had the former finished up but the vehicle layouts and its resource was confusing me on where to go, Thanks for your time i appreciate it!
no prob
