modelling a car is done in 3dmax, zmodeler etc ..start off with those programs ....
I like 3d max alot more , but zmodeler also can have it's advantages ...maybe try that one out , it comes with a decent amount of tutorials and it's for free aswell to start with. http://www.zmodeler2.com/
when you are well on your way to model a car , you can think about getting it into a game.
The models can be made and put in any game you want ..but aslong as that goes , you'd probably be busy for months getting to tunes with these programs before even thinking about getting it into a game ;-)
Im similar with Zmodeler . In past times, im creating some models to GTA San Andreas. I want to create a Ferrari season 2009 model by little modifiying existing model of F1 2010.
Help for Modeling a car (or any parts) for F1 2010.
Also I have the same question. I'm new of this forum. I'm an Italian F1 2010 player. Sorry for myEnglish. So I Think i will use Zmodeler, if this is the best choice. Thanks..
