Blender to FiveM converting vehicles

I was wondering if anyone would be able to point me in the right direction of taking a vehicle from blender (In any state) and import it into a FiveM server as a custom vehicle. I’m quite new to FiveM development as you can tell.

Most of these vehicles that I have are quite high poly. They are already rigged but not for Gta V.

Can anyone help?


If anyone is wondering. These vehicles are from a payed Blender Addon.
