Not sure what I did wrong but I am missing the backroom that's in the screenshots, everything else is there. I put all three files in the custom maps section, any idea what I did wrong?

This doesn't work, the manifest and files are all not working

So for this to work if anyone else wants to use this:
Go into codewalker
open files and open both ymaps (mecanosud and v_int_46)
Under mecanosud calculate all flags and extents
Manifest generator
Generate then save ' manifest_ymf ' (Save it ontop of the old one so it replaces it)
Then it should work.

If it says you are missing a .lua do this:
Create a .txt file and create " stream " folder.
Name the txt file as " fxmanifest.lua "
Inside the .lua put this inside:
" fx_version 'bodacious'
games { 'rdr3', 'gta5' }

this_is_a_map 'yes' "

And save it

Inside the stream file put the _manifest , mecanosud , and v_int_46 all in. Leave the .lua with the stream folder..

Then go to your server.cfg and put " ensure 51c680-Mecano%20Sud "

Then it should work in your FiveM server.
