This topic is intended as a primer on how to apply expressions (programmatic commands) to Nuke parameters. Expressions in Nuke are really powerful and should be part of every compositor's skillset, but they can be intimidating for beginners. = temp_expr2. I created this small guide because during my period of work at Trixter, I've learnt how powerful could be the Expression Node.
