I wasn't happy with the way my clever procedural window transparency shader was rendering using Anything Goos and some domain luck. So I eventually modeled the windows manually.
Here is a quick modo render of the Aerotrain shell with some nice holes cut into to. I will be modifying the skirt as well so that its headlights and exhaust vents have enclosures.
Then my next trick is to delete all the domains from this vehicle and UV map and paint it using 3D-Coat 2.10.
