What's up, everyone! Wanted to make this tutorial that will prepare for the next videos about the viewerstates and making of menus and stuff like that, and not to explain too much of HDA structure figured just to make a separate video. Also, I created a playlist for all the HDA related stuff. th-cam.com/play/PLUBK6gGjWEeqHVowxZYrKkmEcEhyS-dMT.html
Have an excellent weekend, see ya!

Amazing overview! Incredible helpful. I'd love to see you creating a setup using the extra files.
Found this video while trying to fetch all embedded textures, formatting them to opdef and using them as file inputs on an HDA.

at 3:36, for some reason, when I enter pwd() the field does not changes its color to green color and basically nothing happens. Any idea why it happens in my case?

[@viktors_anfimovs]

right click on the field, and go to edit expression under expression submenu. write there and make sure to select a python expression under the text field and press apply.

@@viktors_anfimovs thank you for the fast response.
I've changed the expression language from Hscript to Python. Then right click on the field - Expression -> Edit String. Then I get the small window where I type pwd() and I get the same result. However, after if I type pdw() directly in the fielt I get the pop-up window with the help information about the function which indicates that houdini recognizes the function, but it still not working
