This just started off in an experiment in importing a couple of Poser 5.0 heads into ZBrush along with their textures and setting up a good skin material and things just kept going from there. Heads came from Poser 5.0. The eyes were done in ZBrush, however. I've always modelled my own heads before, but I just liked the way this little experiment turned out. For the lighting I had an overhead white shadowed sunlight coming from above and a brown glow light coming from below. I also enabled soft-shadowing and raised the left side of the diffuse graph in the skin material which helped give it that slightly translucent look. For the holes in the head I used a spherinder with ZCut on in some parts and the eraser tool in others. On another layer I placed the wires and metal spheres that were inside the head. The rest are various gear and cylinder tools using deformations in the deform pallette. The coloring in the background was done with the spray stroke. The cables coming connecting the heads are unskinned ZSpheres. Eyelashes were done with the fiberbrush with ZAdd off.
