i'm comfortable working in 3dsmax and, if it's just a question of making a new sail mesh and using pack3d on the sh4 files (as i'm assuming it would be), would be up to taking a crack at it...
does anyone have any schematics for the various guppy sails?
cheers

edit: of course, the bows were altered on the guppy boats as well, so that's something else to consider (though perhaps after a new sail is implemented... one thing at a time!

)
