Hey i have an issue with my server. As of the last major update (MP Assault I think) my addon cars in our server have stopped working when it comes to tuning. The engine and other items are there but all of the “Tuning” abilities are not. This goes for when you use a menu or LS-Customs. Before the update they worked fine. without issue.
Any ideas or fixes welcome and greatly appreciated.
Thanks in advance!
Further to my post i have now taken all resources out except the addon cars (again which was working) and mellotrainer so i can spawn them and still not tuning. Anyone able to help out there?
Further to this it turns out that window tint also does not work, I have also now downgraded the server version to the 1st July and the issue persists so maybe this is a client side issue as a result of the new update?
Vehicle liveries are also broken so it seems. This means pretty much all vehicle modification is broken at the time being. As i have said I’m running nothing different compared to before the new update.
What mod kit IDs are you using?
One of the addon car packs i made is using ID 1000 up to 1046 the second uses ID 1047 to 1049 and the third uses ID’s ranging in the 2000’s. Yet all of these have stopped working.
The ID’s in the 2000’s are from this pack: https://www.gta5-mods.com/vehicles/ubludock-vehicles-pack-add-on
The other addon car resources i have compiled together my self.
IDs only go up to 1000 since the R* 1290 patch, before they went up to 255 but wrapped around.
Thanks for your reply, however im just telling you what the resource came with and it did work… until recently.
Perhaps more wraparound applied and the R* changes in 1365 broke it again. Try using IDs below 1000 and stick to ones not used by R* DLC.
Hey boron, Thanks for your reply. i have just tried your suggestion and with no luck. Any other ideas?
Okay so i have just taken a look at a different addon car that a friend had and i noticed his had the inclusion of the carcols.meta and the data_file for that. after adding this it is now working, Strange it was never an issue before but hey. Thank you for your help and time elements!
Can you send me the link of the car that your friend had? thank you
It was a resource that he had made using the car from this link: https://www.gta5-mods.com/vehicles/ford-mustang-gt-add-on-tuning
I am afraid I don’t follow what you’ve just said. 
All my cars have carcols and correct resource.lua file.
Same problem, visual tuning applies, same for suspension and turbo upgrade, only engine seems to do nothing to any car.
What have I overlooked?
Hmm not sure, can you share your resource.lua?
resource_manifest_version ‘77731fab-63ca-442c-a67b-abc70f28dfa5’
files {
‘vehicles.meta’,
‘carvariations.meta’,
‘carcols.meta’,
‘handling.meta’,
‘vehiclelayouts.meta’, – Not Required
}
data_file ‘HANDLING_FILE’ ‘handling.meta’
data_file ‘VEHICLE_METADATA_FILE’ ‘vehicles.meta’
data_file ‘CARCOLS_FILE’ ‘carcols.meta’
data_file ‘VEHICLE_VARIATION_FILE’ ‘carvariations.meta’
data_file ‘VEHICLE_LAYOUTS_FILE’ ‘vehiclelayouts.meta’ – Not Required
Edit.: This is my template
hmm, test your meta’s for issues? run them though a validator?
Eeehm, would you recommend some? I’ve never done that… Everything is working (and was before updating ESX!).
Then your issue could be with ESX, please downgrade or take your issue to them.
Ok, thx for the help
