To say that this is a retexture isn't entirely true. It uses the textures that are already included in the base download (made by SinglesCat). However, those were never really destined for the SAM body shape, so there were several inconsistencies when you used it. I originally did some edits and uploaded them to the Hall of Torque, but they no longer host mods; I was in the process of doing some edits for myself so I decided to upload a newer package here. Generally the edits are subtle, but hopefully noticeable, mostly fixing seams and so on. Bear in mind I'm not a texture artist, so the work isn't going to be 100% perfect, but I hope it's acceptable.
I included facial textures, but I didn't edit them. I included them only because they are no longer available on SC - Khajiit Improvement, and the body textures simply won't match with anything otherwise.
I tweaked the smooth and striped diffuse textures to remove some seams along the inner leg. There's some lighter color sections that didn't match up, I did some cloning to close that seam a bit. This was more noticeable on the smooth texture, so that's where I focused the work. I also added shading for a belly button and nipples. SAM's body mesh has them modeled in, so I figured I would add them. The belly button is just simple shading I did, but the nipples are from the Lykaios Race by KrittaKitty. I also added toe nails that were used from the hand mesh, personally I use a set of toe claws I modified so I don't even notice it anyways. I copied over the pink toned flesh that ShinglesCat put on the palms and soles in her newer version of her textures, and put them in here. Vector's original genital texture was meant to match up with Bethesda's, creating a seam, now it should be mitigated.
With certain ENBs the specular lighting on the hands and feet were too high, and as a result created a seam. I reduced the specular lighting here to reduce some seams. The same is true sides of the body, and the hip/groin region.
I heavily edited the normal maps so that now when your character's weight is at 0, or you have high values of samuel, there's less muscle definition. This is most noticeable in the chest region but I smoothed out everywhere else as well. For higher weights I added abdominal definition, and more definition in the pecs, they should appear a bit more smooth now than before. The abs aren't quite as defined as some of the mods I have seen here, but I was going more for a look that was in line with the Vector's textures. Finally, I swapped some of the channels for the normal maps on the tail. This was present even in the vanilla game. Basically light hitting the tail from above would be treated as if it was being cast from the front, and vice versa. This was most noticeable in front of something like a fire, or outside, where your back would be bright and the tail would be dark, or vice versa. The tail should match the body now. I included a before and after picture if this doesn't make sense.
