Oleg M wrote a great tutorial for creating scratch made cars in ZModeler. You can get this tutorial on our nfs4/nfs6 tutorials section or directly here.
It REALLY is!!!!Helps VERY much.Thanx guys.But some sample .z3d files seem to have a problem (ex:files from step 5,6,7 and more)(I'm not sure if it only happens to me).When i open them Z-mod crashes.I'm running XP Pro.
