A maker of DAZ based content named "JoeQuick", when he was still sculpting just for fun, made a likeness for me of the John Friedlander mask as worn by Michael Wisher.. I applied it to the intended base figure (Michael 3) and it distort the head to closely resemble the injured and withered Kaled scientist. Then I wondered, "How might it look if I only dialed it to partial strength, say, around 50 percent?" So that's what I did. I applied a more conventional skin texture (which had heavily mapped eyebrows) and I placed a simple brushed back hairstyle. This was years before Capaldi episodes, so I used black (aged to a dark grey) rather than the dirty blonde "kid" Davros had. It was just dumb luck that I gave him piercing blue eyes.
Anyway, this was the result.
Yeah, I went a bit heavy with the "bump maps" and this was rendered with an "engine" that could not calculate things like "subsurface" light scattering upon skin, so it's quite primitive compared to what can be done with more robust tools available today. But it does give us a "glimpse" of how he
might have looked before he aged into the twisted caricature we saw in "Genesis of the Daleks".
