Linus Rosenqvist shows how to have a vector stay relative to its transforms in Houdini.

You can likely find a few solutions to how to make a vector rotate in your Houdini scene. Some of the answers will break apart when you choose a new direction, depending on what the object’s animation does. This new tutorial from Linus Rosenqvist shows how you can have a vector stay relative to its transforms in Houdini.

 Rosenqvist attacked this problem once before, but this new method described in this tutorial is a much more elegant solution.
