As you can see, this is a close-up shot of a bloke driving an Ariel Atom. Gotham programmer Chris told me: "The driver is completely lit and shadowed in real-time - there are no pre-baked shadows in any of the textures used." In other words, those creases in the suit aren't drawn on by an artist. They are actually there, in the game, generated by virtual light sources like the sun or city street lamps. Chris continues: "The driver casts shadows onto the car interior and receives shadows from the car itself for maximum realism. There is also a high resolution bump-map that adds a fine cloth-like weave to the driver's suit." Although I personally think it looks great already, Chris is also keen to point out that "this is all work in progress, and needs plenty more tweaking..." Apparently it'll look even better in the final game!
