Maybe he used Search, as everyone here keeps yelling for people to do.
But this is a great thread to bump. As ParkourVeyron says, vote for it in the Feedback tab at the top of the page if you like it. I did.
As I said previously, a Livery Editor is almost essential for those of us who want to have our own racing identity, as every real life race car driver has. Or an online identity. Or to form a club or league, to allow everyone to identify themselves to each other and the world at large. As I feared, right now if you don't use the handful of Race Mod cars with their one livery template, you have to pick colors. Meh.
The marvelous Livery Editor, combined with the extensive real world body mods you can use to build race cars, are the two things which kept me coming back to Forza through four games. I'm hoping that Kazunori is well aware of all these factors, and does intend to include them in Gran Turismo by GT6.
Well, I definitely wouldn't say the things added to Spec II were pointless, or the DLC either.
Keep in mind that Polyphony just went through a terrible disaster which affected most of the country. At the very least, electricity rationing had to hit them pretty hard, they don't have their own power plant after all. And then, Kaz moved the studios hundreds of miles too.
Even if they hadn't had to deal with all that, building a proper, bug free Livery Editor has to be a serious job that can't be done in a weekend, or every game would have something like Forza's system. We have to be patient. I want every car to have some kind of Race Mod for it, even the 800 Standards, and that's surely a tall order.
