In-Depth Information
A typical rendered image can be broken down into four main components: diffuse, reflection, specular, and
transparency. You may recognize these as elements of materials that have been created throughout the course
of this topic. Just as these elements are combined to make a finished texture, they also make up the finished
render. The Final Color output is commonly known as a beauty pass , because it features all of the compon-
ents of a fully lit and textured scene. In many cases, this will probably be enough for editing purposes. You
may be wondering why the individual components are necessary if the Final Color output contains all three
of them. The reasons are flexibility and speed. By having the diffuse, reflective, specular, and transparent
elements separate, they can be adjusted without affecting the other elements. To further explore these ele-
ments, you will add a preset car into the scene. Figure 12-25 shows a final render of the alley scene with an
Alpha Romeo from the modo stock content inserted into the scene.
Gamma Output
Many people render with outputs and then get discouraged when they open the layers in Photoshop and
are unable to get the look of the final render. When rendering a final output, the Gamma defaults to 1.6.
Render outputs are set to 1.0 by default. You can adjust this setting in the properties for each output, in
the render window for each layer after the render is complete, or in Photoshop after opening the layered
file. It is usually best to adjust the gamma in the properties for each output before rendering so that it is
correct from the start.
Figure 12-25: Final Color (beauty pass) shows all of the inputs combined as a complete render.
