Nope. I guess we'd have to include it in every ship.
But then again, what's really canonical in VS?
I look at the llama in-game, for example, and the texture is a mixture of:
- recessed areas with a shiny gray metal and darker stripes
- non-recessed areas are a dirty-brown material
- random grooves everywhere, where the bottoms are shiny metal
All of which seems to suggest that it is a metal hull that is covered with something
like tree-bark, but some of the tiles fell off. I don't think there's any chance of stumbling
on a rationale for the texturing. I've seen ships covered in what looked like a circuit board,
like a matte background and copper lines all over it. I've seen ships looking like cement,
or varnished wood or blue plastic or ... anything except wicker. I don't think people would
look at metablack patches and ask "what's that?", because if they did they'd have to ask
the same question 7 million times.
