I don`t know what size you`re using, but usualy the texture don`t need to be bigger then 2x the size of rendered image(if object is on full image).
But I don`t know what are the NL limitations for M~R texture size. I hope they tell us.
Try to ask some guys who are doing the Breaking Barriers pics, maybe they will now..
