i’ve got 1 mesh.
it has 2 uv sets (one for the body [0,1 uv space], one for the head [0,2 uv space]). ***this means the head roughly takes up as much texture space as the body.
i can’t hide the seam where they meet w/ anything, and i need to make the seam disappear.
any suggestions?

First, is this happening with displacement map or texture? Knowing where you’re having the trouble will help with giving a solution. 
absolutely, aurick. it’s a texture map.

Ok. With a texture map my recommendation would be to use ZAppLink.
First off, I assume you’re using polypaint? If not, you should be!
Then it’s simply a matter of selecting the subtool that you are wanting to paint and using ZAppLink to send it to Photoshop. You will now be able to use things like the Clone tool to copy from the other subtool (which will still be visible) to the new one. Photoshop’s other features will be available as well. In short, you’ll be able to get a perfect transition between the two subtools. When you return to ZBrush that will get added to the model’s polypaint, which you can later convert to texture.
If you still get problems after that, then they would almost certainly be due to UV issues. In which case no amount of texture-side effort will resolve the problem.
i wasn’t using polypaint, but i had been using zapplink.
however, after splitting the mesh into 2 subtools by selecting polygroups>uv groups and then subtools>grpsplit, assigning textures to polys (txr>col), and using zapplink to fix the seams, the edits fail to take.
i activate zapplink
do my seam cleanup in photoshop cs3 and return to zbrush to accept the edits
after i press “pickup now” the edits disappear and i’m left w/ the exact same seam as before i went into photoshop.

after searching for hours i found atleast 4 threads like these…that never are resolved…a little help please
If you’re using 3.1, this is an easy answer: there is no support for any UVs outside of the 0,1 space. If you’re on a mac w/ 3.12, then I have no idea, because they added multiple UV support in 3.12
okay, forgettin the problem with uvs outside 0,1 space…i isolated my head which has the uvs in 0,1 space…i keep getting a seam where the uvs are split…i painted over the model in projection master…dropped it…and when i pick it up i have a seam where the uvs are split…
so i use the z app link to fix the seam…but when i pick it up again…boom seam is back in the exact spot…what gives?
Hey, there Sandman79x. There is no way to get rid of the seams in Zbrush. You can make it look less visible by trying to crank up the FS Border number under Tool>Texture before you hit the Col>Txr button. Normally Zbrush tries to make the seams less visible automatically when you hit the Col>Txr if I do recall aurick the supermoderator mentioning it on some other post. Zbrush does a pretty good job of making the seams less visible. Try experimenting with a couple of tries and see what the end result is after you apply your colors to texture.
If you are still not happy with the seams showing up I suggest Photoshoping it. Though doing it Photoshop can be tedious trying to paint over every single seam but it gets the job done. Another app you might be interested in is Bodypaint 3D which I hear is a good texturing app for getting rid of seams.
Sandman79x - You’re going to kick yourself when I tell you how easy this is to fix.
change the material to ANYTHING BUT flat color.
For some reason Zapplink doesn’t work with a flat shader on.
It’s not really a big deal though because you can turn off all the lighting information right inside PS…so you get the same effect when you work.
Anyway, enjoy.
