If
you went and unhooked the Reflection Shading (the red one), you??™d see the change in the
surface sample and no reflection at all, even though the Alpha is still connected.
Working with the Node Editor can be confusing at first, but stick with it and read on to
learn more.What??™s important to keep in mind is that there are many different types of
nodes, all of which can be connected to build a surface, just as you??™ve done in this exercise.
Although you??™ve added only two nodes, you??™ve created a node-based surface just the same.
The next section explores the outputs and inputs of nodes, and explains how the colored
dots represent the variations.
Outputs and Inputs
Having worked with the Node Editor briefly, you might be annoyed by all the values, settings,
and colored dots on the nodes. But don??™t worry; you??™ll soon see how it all comes together.
Keep in mind that almost all nodes, except for the final destination node, have both inputs
and outputs. Inputs are on the left of the node, while outputs are on the right. Therefore,
a good way to work is a ???left-to-right???workflow. Although this isn??™t necessary, it??™s a good
practice as you string together nodes to build your ???network.
