You can make the freckles more or less visible by adjusting the brightness of Color 2. You can make the freckles more or less numerous by adjusting the Low Clip value of the noise shader. You can make the freckles bigger or smaller using the Global Scale attribute of the noise shader. Take note of the color setup and the Low Clip setting in this example. We are using the Poxo noise shader, which looks like small disconnected patches of color. Click the small preview square next to the Noise shader, and set it up like the illustration you see here. button, and select Noise from the drop down menu. Set the Mix Mode to Multiply, and then click the black preview square to enter the Layer shader properties. In the color channel, click the triangle next to the Texture parameter, and select Layer from the list. We can add these to our base color with the use of a Layer shader, and a couple of noise shaders.

Skin also has a number of imperfections such as freckles, moles, and veins. The rendered result looks a bit corpse-like, which is normal-we have not added the effect of the blood coloration yet. Here is the base color for our skin shader. More on that at the end of this tutorial. If you want to create skin of other races, you'll be modifiying this base color. So, for a first pass at skin, set the color channel of a fresh C4D material shader to a yellowish shade. For reference, look at the thick caluses on your feet-you'll see the color I am talking about. The blood has drained from their face, revealing the true color of the skin. This is why people "turn green" when they are seasick. The pink coloration comes from light scattering in the blood under the skin. It might come as a bit of a shock, but skin isn't peachy pink (if you are caucasian): it's actually a kind of greenish grey color. All of these skin solutions have some basic settings in common surface color, specular settings, bump settings, and sheen. I'll examine Cinema 4D's native SSS solution, and finally, I willl show you a powerful third party shader that overcomes a lot of the limitations of C4D's solution.Īs in the glass tutorial, I am going to take the surface properties of skin and break them down part by part to explain the settings I will be showing you.

I will demonstrate how to quickly fake this effect using some basic shaders built into Cinema 4D. This effect is widely called "Subsurface Scattering", or SSS for short, and is a property of a number of translucent materials wax, plastic, milk, and marble, to name a few. That means that in addition to the light that reflects off the skin's surface, light bounces around the layers of flesh below the skin, illuminating it from the inside.
Skin has a particular quality that sets it apart from ordinary surfaces: it is luminously translucent. In this tutorial I will examine a few different strategies for achieving a realistic skin shader in Cinema 4D.
