Quick question: Facegen Artist Pro doesn't generate bump/displacement maps -- only diffuse -- and I'm no texture expert, so...what' he way to get bump/displacement mapsb from the diffuse map? if that makes sense. lol

Subscribing, good question

Sound like time to dive into photoshop or Gimp and learn how to edit/create textures, LOL.
For personal use you could always try using the normals and bumps from other texture sets, but results may vary, especially around etailed areas such as nipples, hands or face.
Does facegen even make decent torso maps? I remember checking it out ages ago and I think it at least tried to make skin maps but they had terrible seams. A textured head isn't very useful by itself.
I think the idea, or at least this is the way I perceive the texture setup instructions is, you continue to use the default normals and bumps from the base figure and just change the textures you are directed to to allow for the newly generated maps. That seems to have worked pretty well for me. One has to accept the fact that FaceGen is focused on personal usage and not product creation.
You have the option of OR-ing the textures that FaceGen makes with the default Genesis <VERSION> texture set or any texture material set for a Genesion <VERSION> character like Michael 8 or Stephanie 8 and so on. It only ORs with the diffuse parts of those material sets not the normals, bumps, cutouts, displacements and so on.
It's not horrible, the results can look quite nice, but if you want the results to look more like the person FaceGen is copying then creating normals, bumps and such using the link Wendy gave to create those maps using plain FaceGen diffuse textures is probably a better ideal for accuracy. You could then use those as a basis to learn texturing yourself by iterating multiple times in improving them.
