I think I found the problem, i overlayed the russel texture with both the David and M3 texture in photoshop and turned down the opacity so i could see all three, and i noticed the russel nipples are slightly larger then M3/David, also the center of the Russel nipple isnt centered with the David/M3 nipple. This would explain why its stretching beyond where it should, i tried correcting it in photoshop but im not the best with that program. I tried sending a message to the artist hopefully they will respond. :)
