Ground Vehicles

[Buster_Dee]

At some point, I'd like to dust off a few ground vehicle models I started years ago, with the hope of making them driveable. I'm up to my chin with projects at the moment. But, does anyone know any of the requirements for modeling ground vehicles? I see alpha channels and bump mapping. The tires have me stumped, as the alpha'ed sidewall perimeter seems to be joined to the lower poly tread (no gaps or bleed-through).

Excure me if I don't aknowledge a response. I'm off to spend some time with "long-lost" family.

Thanks. I'll nose around when I get caught up.
