Poser Cycles shader for tattoo overlay onto figure by ibr-remote Poser Cycles shader for tattoo overlay onto figure by ibr-remote
Software: Poser Pro 11

Here , I show how I assembled the Cycles surface shader tree for a layer above the base texturing for the Paul 2 Figure.  This is for his Arms Material Zone.  I added a layer, then created the shader tree as shown.  I used my painted image as tattoo source as well as transparency (see my nodes for how I did that).

Progress of My Tattoo Shader Development:

My preferred single-layer tattoo shader solution at the moment:
fav.me/dcxavm4
(classic solution known to all Poser software users)

My less preferred 2-layer tattoo shader solution:
fav.me/dcxaxkk
(I will work some more on this one)

LATEST - I keep getting a horrid and just barely visible defect in the rendered image where the arms and the torso material zones meet.  I have no choice but manually convert the tatoo textures into transparency maps using Clip Studio Paint, and apply them in conventional Cycles shader tree.

I have received suggestions for improvements to shaders for hi-fi rendering, courtesy of Ghostship from Official Poser Forum by Smith Micro. 

The solution works without adding layers to the material zone (ie, works on the Base Layer as a modification to the existing shader tree).

If using SSS for base layer skin shader tree, filter out the red colour from the tattoo image map using the appropriate node.  This avoids the tattoo image from affecting the base skin colour.  This also works for makeup.

Also, to avoid the appearance of the tattoo as a decal, UPDATE: apply the transmap directly to the Cycles Root node Displacement.  I will do a screencapture later to show the updated shader tree setup.
