  4. Select all the codes and press Ctrl + Enter for Win/Linux or Cmd + Return for Mac.
  5. ???
  6. Profit!


Expected Result

What Should I Do Next?

You can use the result to help identify the read nodes in your script so you can safely move or delete any unused renders from your storage.

Basically there are endless opportunity like discovering the wonder of Python scripting for Nuke, bragging rights to your fellow colleagues or classmates that you have succeeded in running a custom Python script in Nuke and so on!

Nuke Tips – Clamp Node

Clamping the Clamp Node

Update 1st July 2018: Here’s the link to the cabin depth render for your exploration. Credits to for the original model.

Nuke Tips – Bookmarking Nodes

Bookmarking Nodes for Quality of Life Improvement

This will be a short Nuke Tips as the other articles I’m drafting are longer than the usual length.

If you ever wonder if there is a way to quickly jump to a node in a large script, the Bookmark feature comes in handy.

Just check the Bookmark checkbox at the appropriate nodes (the Backdrop nodes are enabled by default). Also remember to label the node with a nice name. Preferably something that doesn’t replace the original name (e.g. Write1 as Write_LowResPreview).

There are two ways to quickly jump to a bookmark.

  1. Go to Edit > Bookmark > Jump to Bookmarked Node OR…
  2. Press J to pull up a dropdown list of the bookmarked nodes ala Tab Menu

So… Is It Useful or Not?


If you have less than 30 nodes…  bookmarking nodes does feel like a chore but it is nice to have that flexibility in case we need it!

Plus the Backdrop nodes are already bookmarked automatically upon creation so it is a nice way to quickly jump to a particular backdrop section.
