Adding Other CGI Images
There are two other elements to add to the lemming: the hair and eyes. These passes were
rendered separately for several reasons that are not important here. These elements don't
have passes—they only have a beauty pass. The hair will simply be added to the rest of
the tree. However, the eyes need to be cut so they fit the eye sockets, so you will use the
ID pass for that before adding them to the rest of the tree.
1. Withnothingselected,createanotherDotbypressing.(period)onyourkeyboard.
2. Connect the new Dot's input to the bottom right Dot, the one that ShuffleCopy1
is connected to.
3. Place the new Dot underneath that Dot to create a new branch to start with.
4. Copy Shuffle6 (ShdSelf pass) and paste it after the new Dot.
5. Change Shuffle7's In 1 property's pull-down menu to Hair.
6. Make sure all four channels are shuffled from the left—Hair input. This means
you need to check on the alpha channel box on the left, In1, side ( FIGURE 3.46 ) .
Figure 3.46. Changing the Shuffle node so that the alpha is copied as well.
7. Select Shuffle7 and press M on your keyboard to attach a Merge node to it.
8. Connect Merge6's B input to the output of Premult1 and place Merge6 under
Premult1, and then view it in the Viewer ( FIGURE 3.47 ).
Figure 3.47. The hair elements should be added like this to the tree.
