Compositing the Occlusion Pass
You will now add one more Blend & Comp tool to composite the occlusion
pass over all of our other nodes. Use the quick copy and paste method you
learned earlier, along with the Alt key, to fit the new node in the flow.
To compositing the Occlusion Pass:
1 Hold the C key down and click and drag the last Blend & Comp to create
a copy of it.
2 Then, with the new Blend & Comp selected, hold the Alt key and drag
the new copied Blend & Comp tool on to the connection line before the
output node. It is added to the flow.
3 Connect the occlusion pass image import nodes output to the front
input of the new Blend & Comp node.
