    Okay, so I'm obviously not understanding what to do... The larger area represents a single seamless swatch that is tiled. The smaller region render represents a composite map with noise map masks. Both the material and noise maps masks are offset from one another. Yet it renders the same. Bumps and Displacement are off as well. Any further help would be deeply appreciated

      What are the offsets for the textures you are using? Should not be whole numbers like 1.0, 2.0 because then it would end up at the same place.

        Since it doesn't go above 1, I tried increments of .1 and also .2 for each. That made no difference.

        Currently:
        Top of stack .8
        Bottom of stack 0 (decrease by .2 each time

              I think I did it! The burlapy feel gets a bit lost, but at least there's no visible tiles. Turns out I was trying to change the positioning in the bitmap parameters and not the actual coordinates... Also, it seems like a smaller (1-2) noise parameter works well. Larger parameters made it look really soft.

              Thanks, everyone!

                A good thing to try doing is use your render elements to check out your masking. Put in an extratex element with each of the noise maps you're using (so 4 of them in your case) and see roughly what size each of them appears at in the final render - if they're really small they won't give you a huge amount of benefit and are just making things fussy, you probably want each blotch of noise to be about the size of a tile roughly so you're getting plenty out of each layer. Also get rid of the mask on the very bottom layer, you don't want to accidentally see through to the bottom layer and have that masked out in areas too or you'll have holes visible!
