i too think it is the texture filtering.

P7 has texture filtering assigned to the material by default when you bring something in, however, it sets the texture filtering to "Quality" (as opposed to "none" or "fast")

P6 only has the one texture filtering option (on or off). also note that when you used texture filtering in p6 with a DAZ figure and typical DAZ skin texture you get white lines along the seams because the texture is shifted/sampled beyond they typical area. So i would think that it is P6 that has the shifted texture, and P7 has corrected this.
