Using Render Outputs
In many cases, after clicking Render, your image is completed and ready to present. However, much can
be accomplished after the render is completed. To do this, a fair amount of preparation needs to be done to
get the most out of post-processing. Unlike post-processing, post-processing 3D rendered images can offer
many options and tools for making the job easier and affording you possibilities that are not available when
working on photographs. In modo, render outputs can be added either by duplicating an existing output and
then right-clicking to change the actual output or by selecting Render Output from the Special section of the
Add Layer drop-down menu at the top of the Shader Tree.
Render outputs tell the rendering engine what kinds of images need to be produced. Some options are
used directly, others are used for image diagnosis, and still more are used indirectly to enhance the final out-
put in post-processing. Here you will consider some of the most useful render outputs and then look at how
they can be utilized in post-processing. The outputs covered here are Final Color, Diffuse Shading (Total),
Transparent Shading, Reflection Shading, Specular Shading, Alpha, Surface ID, Depth, and Ambient Occlu-
sion. The first five of these are essentially components of a final render and the other four are used to derive
some additional effects for the editing of final images. To continue, you will look at each of these groups in
more depth.
