the problem is that texture variations from the face room (shading and such) doesnt append any info onto the body. its just the face, so what you endup with is a textured head with a very definate line of demarcation between it and the body texture. what i have done is to first use the figure texture.. !not the default face texture in the face room! at least i have a fighting chance since the default on figures face matches its body texture. then when changing any of the texture variations i just keep an eye it. when im done i go to the material room and in my diffuse, i tint it to match. good luck.
