Clarification: in the above, you'll be using a SINGLE texture, applying it to both head and body. You'll need to merge the head and body seam guides. Re-size the seam guide images to identical sizes (such as 2000x2000), so that you can combine them. White out all, except near the seams. Load result on to head & body - seam guides should line up. If doesn't, then you need to use UVMapper to make new head & body templates that are both 2000x2000 (or whatever). That is, START with a pair of templates that match; UVMapper is great way to make such. (Hide all but head, save out template for head; Hide all but body, save out template for body) Re-size and re-position the pieces of the seam guide that you need, on to those UVMapper-made templates. Now white out other areas, and overlay the two templates, being careful not to move either by even a single pixel! NOTE: I see that M3 has fine enough detail in its mesh, that determining direction isn't too bad (shouldn't get significant "veer" as cross seam -- just follow one of the mesh edges).
