Character<br />
Finishing the design<br />
Giving the character the Pixar look<br />
My main goal in this image is to work with the skin<br />
09 shader and this is what I dedicate most of my time to.<br />
I’ve discovered from previous projects that there must be wellestablished<br />
lighting before testing the shaders. This is why I build<br />
a rough lighting setup before anything else.<br />
I always thought the lighting of the piece should be subtly<br />
10 contrasted; this way I can get delicate light bouncing in p<strong>art</strong>s<br />
where visual attention is critical. The lighting setup is the basic threepoint<br />
light formula: a light simulating the sun, a Fill light in the left side<br />
and a Back light simulating the reflection off the wall.<br />

After I define the<br />
11 scene’s mood with a<br />
basic lighting setup, I focus on<br />
the skin shader. I use the SSS<br />
Fast Skin shader, which can be<br />
found on Zap Andersson’s<br />
blog (http://mentalraytips.<br />
blogspot.com). This shader<br />
gives you more control over<br />
reflections and also the<br />
material specularity.<br />
When I’m happy with the overall look of the shader, I<br />
12 proceed to texture the most complicated elements of the<br />
scene such as the sweater, the bag and the skirt. This means I can<br />
get a rough idea of how all the elements are working together and<br />
also check if some tweaking is needed in the texture values or the<br />
lighting setup.<br />
Colours and<br />
materials<br />
After I texture the background, I work on the paintbrush in her hand. For this I create a new file so I can<br />
13 control the lighting and rendering parameters properly. The last step is to gather everything in Photoshop in three<br />
layers: the character, the background and the brush. With a few final tweaks, I have the result I want.<br />
The biggest challenge for me in<br />
this image is to achieve the look I<br />
have visualised with the combined<br />
effects of the lighting, skin shader<br />
and the character’s clothes. If we<br />
look at the original concept <strong>art</strong>,<br />
one of the main characteristics of<br />
the little girl is her multicoloured<br />
sweater. As a result, its modelling<br />
turns out to be a significant<br />
element as I don’t want it to look<br />
too rigid or heavy. This is why I<br />
decide to go to town with the<br />
knitting texture. I achieve this with<br />
a good Bump map and some fine<br />
tweaking in the Diffuse channel.<br />
