That's that. Both views are now ready.
Creating stereo-view proxies efficiently
You need to bring one more element and perform the same processes on it. It will be a lot

Read node and use a variable to tell Nuke that there are both a Left and a Right view. A
variable issimplyaplaceholderthattellsNuketolookforsomethingelse.Inthiscase,the
variable will be %V, and it tells Nuke that it needs to replace this variable with whatever
is in the Views list. In this case it looks for Left and Right.
1. Create a new Read node and navigate the File Browser to the chapter08/Bul-
letCG/full/ directory.
Here you can see there are two sequences. One is called bulletCG_left.####.exr,
and the other bulletCG_right.####.exr. Replacing Left or Right with %V will en-
able you to use only one Read node.
2. Click the first sequence in the list, the one indicating the left eye.
3. In the path bar at the bottom, replace the word “left” with %V and press Enter/
Return ( FIGURE 8.31 ).
