Ah yes! If you wanna go down the whole floater rabbithole, there's a great thread about it over at technical talk http://polycount.com/discussion/155894/decal-technique-from-star-citizen/p1 gl hf
If you like you can also add unique (aka not tiling) details (like writings etc.) as floaters with their own texture. I think they did something like this in Evolve (remember an post here about how they approach their building).
