raincole 2 Posted January 15 I'm talking about the Python scripts in an HDA: When I press "Edit text in an external editor", it opens my editor of choice (VScode in my case): But it's a *temp* file. When I make changes there and save it, the script in Houdini doesn't change at all! It's definitely not how I expected "edit in an external editor" works. I googled and found this: http://cgtoolbox.com/houdini-expression-editor However, it only works for parameter expressions, not for scripts in HDAs. Share this post Link to post Share on other sites
