The thousand credits asking price is really a token gesture. No one would miss it. You get more than that for logging on. Lol. Besides your storefront doesn't tell you who has bought what. I would message the guys if possible.
Yes the editor is really good mate. Very versatile and powerful. I read had a peek at your liveries and there very good for what you are limited by.
For comparison Forza allows 1000 vinyls per side and roof = 3000. Plus 500 each on bumper and boot. 4000 total.
My Jagermeister livery whilst might not look like much actually cost a lot of vinyls. 125 to make 12 letters. 250 if you want an outline.
The side of the BMW has 1 outlined one 250. 2 normal ones. That's 500 out of your allocation already. Then the Dear heads at around 120 odd each and that's your lot.
A seemingly bare design using nearly all the layers. I've created a far busier looking design with around 300 layers. It's all down to the intricacy of the shape.
The roof on the car I've just finished is at the 1000 limit. With 8 logos. Argh.
