Texturing tequnique question

[SinnopS]

I am trying to figure out what the best way is for texturing a variety of models that I have for an upcomming videogame. Mu problem is that the game has a huge range of scale, from small fightercraft of a few meters to space staions up to 100km. I am unsure of how to go about texturing all of these so that the textures do not become insainly blury on the larger of the objects and how to add small details for such huge objects. I figure for the really big stuff i would have to use multipul textures but how would I go about making sure everything lines up properly and maintain the same level of detail between textures so that one does not become more distorted than the other? any ideas?

thanks
