Step 2: Correct the reflections in the eyes
The only other things that I found needed to be changed from the scan were the eyes. This is because they reflect all the DSLR cameras used to capture the 3D portrait - which are of course needed to capture all the details, but they don't fit the scene that I want to place my 3D model into. So I instead look for an image of dark brown neutral irises, and lay them over the old ones. You can see the difference here:

Step 3: Skin Shader Image Maps
To make the other face image maps of ‘My Kiwi Friend' in MARI, I recommend reading part 2 of The Fisherman tutorial
for an in-depth guide, as the process is exactly the same for both portraits. Here you can see an overview of the different maps needed for the Skin Shader in MODO:
Each of these image maps will contribute to the end result in its own subtle way
Step 4: Body epidermis map in MARI
Rather than focusing on the head - as we did in The Fisherman tutorial
- let's take a look at the image maps for the body model here, which is separate from the head, as I showed you last week
To keep things organized, I copy the Color Channel in MARI and rename it ‘epidermis'. Now I need to desaturate the base Diffuse Color map. So I add an Adjustment Layer and choose HSL (Hue-Saturation-Light). I lower the Saturation to about 0.650. Next I add a Layer Mask and, with black selected as the color, I paint a mask to recover a bit of Saturation on some fleshier parts of the body. This helps to get some variation and avoids it coming out looking too flat. I like to use the Super soft Brush Preset for this kind of work.
The only thing left to do now is to export this result as a flattened image map for use in MODO. So right-click on the ‘epidermis' channel and choose Export Flattened/Export Current Channel Flattened.

Step 5: Create the body's lower dermis map in MARI
Next, let's make the image map for the Lower Dermal layer. I copy the Color Channel, which holds our base, and rename it ‘lower dermis'. This map has to have some quite increased contrast. This is achieved by first adding a Contrast Layer and increasing the value to about 1.700. The levels of this result are slightly changed with a Levels Adjustment Layer. Then I simply export again.
