Errm...   okay, I got a little bit sidetracked as you can probably understand from the image above ;) I was going through some brushes in Photoshop to make a good tattoo when I came across Ron's Suds brushes.  So I loaded some suds into the tattoo map and plugged into the displacement channel as well and I'm pretty happy with the results.

I managed to adjust VSS so it applies the suds over any texture although my setup only works for V4 and M4 characters.  This could of course still be used for tattoos :)  I´m making a minitut that I will post shortly but my internet connection is very bad at the moment and I´m not sure I can post at all.  But if you're reading this, it means I probably can...
