Thanks for your reply, gster123. I used fast_skin directly on the head mesh plus the Brownian 3D displacement map but I understand what you mean about using UV and doing it outside because there's no way to do random spots unless its done that way. I might export the Brownian texture to Photoshop and then add random spots later as in Dr Julian Mortimer's tutorial.

But UV mapping the lips and eyebrows with an external texture file and leaving Maya's misss_fast_skin on the face would be quite difficult I think but I'll give it a try.

As you noticed, I don't have ZBrush (or MudBox) which is why I haven't textured directly to the face in a 2.5D kind of way :-) but hey, you just gave me an idea - why don't I try downloading the trial 3.1 30-day version and see how much better I can make the head with it...
