My god I searched for a tool like this one without luck, how did I miss it ?? Thanks, this will be useful
@roylapoutre Truck ads are in the ytd/+ytd's for trucks. Such as the Mule.
For the billboards, try this: x64i.rpf/levels/gta5/_citye
One mod on this website gives a more exact location: x64i.rpf/levels/gta5/_citye/downtown_01/dt1_22.rpf
Thanks for the answer ! I already found the truck textures, but for the billboards, it's not the only location, I found others elsewhere unfortunately ^^ I think the solution from ReNNie will be a lot easier to find any texture.
