This is part 2 of my Nuke Expressions Basics series. If you haven’t watched part 1 you can see it here.
In this video I will look at referencing data from different frames in your script, and using time to create complex procedural animation. Then I explain if statements and using the $gui variable to speed up your scripts while you work. And finally we look at using expressions in text nodes and labels, to help us keep track of what is happening in our script.
I mention Attila Gasparetz’s blog in the video. You can find his TCL snippets here: https://www.gatimedia.co.uk/tcl-functions
