That's an irrelevant detail that can be left until the tbling stage. In other words, I'm too lazy.
And the end-of-semester crunch is hitting hard at the moment, so I have to put this off yet again... and besides, Wings3D's UVMapper leaves much to be desired. You'd think it would be simple to select a bunch of polies and map their projections on the x-z plane exactly as they look on the xz plane
, but noooo, they're all separated into piles that make no logical sense whatsoever.
