Advanced 3ds max user need help creating cars

[Eclips]

Hello as u read from my title I am an advanced 3ds max user needing help creating cars. I have already gotten the script needed for importing and exporting dff files. I have played around with it a little and imported some premade cars, I know how to use GTA IMG tool both versions, the only problem is I dont know what is needed to create the car poly counts dummies etc and I also have experience creating halo maps, vehicles, and guns so if technical terms are needed feel free. Thanks in Advance. -Eclips P.S. I also have Aim:roketboyd MSN: [email protected]
