LearnDay - HOUDINI Python Introduction

LearnDay A webinar series EVERY WEDNESDAY with different topics, you can as ANY question and I'll help you live.

Today we learn the basics of Python and it's uses inside Houdini, it's used all over Houdini to make most of the tools, by the time we are done we'll modify and make a few simple tools using our newly acquired Python knowledge

PLEASE ASK ANY QUESTIONS ANY TIME, this webinar is FOR YOU.

Please subscribe to the channel to never missed a webinar, trix and tutorials.

I remember watching this video 5 months ago, it was all alien to me. But i took the time to learn python on my own. Coming back here, it's as if my eyes became opened. "Knowledge" is indeed "power". Thanks for this video.

Nice tutorial, anyway a little critique :)

The "some reason" about the hou.Color parameter being in parenthesis is because the hou.Color constructor requires a tuple.
I know It looks like basic stuff, and I don't want to be a pain with this, but it's quite important and worth to be precise about stuff like this to spread a solid Python knowledge :)
Thanks for your work anyway, it was really helpful as an introduction!

P.s. an additional tip to 16.5 users.
Apparently when you create a node via scripting, it will always connect it automatically to the last one in selection stack. So if you are getting multiple connections with the merge code, put "hou.clearAllSelected()" to clear the nodes selection before creating the merge one.

Hey, thank you sooo much! I'm totally new to Python (It was worst nightmare in my artist life), and now, i started to understand. Thanks

Cool stuff man! I'm happy that I found this tutorial and I would want see another additional tutorials like that. I like your diction, and manner of speaking, I can undersatnd everything what are you talking.

Your video is very helpful thank you. One improvement I would make is to move the overlay of your webcam away from the python script output window.

[danielhartmann]

Thank You for sharing Your knowledge👍 Really highly appreciated!

I wish someone would publish a book "Python in Houdini for beginners"😊😊😊

[sarasaccone]

Thank you so much!
After this tutorial could you suggest me some other sources from which I could learn Python in Houdini?

[massadian]

Thanks. You don't need to import objecttoolutis or soptoolutils in the cases you show, it might be disturbing for beginners. These libs are meant for user interaction (either to place the element in the 3D Viewport or in the Network view).I would suggest you use .createNode("null") and .createNode("merge")

Please if you have time a webinar about VEX would be really awesome,

[linusrosenqvist]

Maybe add comment about tuples? It's kind of an important feature that you can't write to one.

[javisartdesign]

Awesome tutorial! Hope you will cover some more advanced python features in the future :) By the way, could you explain some assets that are available in QLib do you think are better to use rathen than normal houdini that comes originally with the software?. Thanks . Regards to Roberto.

speaking of Nuke like behaviour - can you capture mouse events, say like - how would you go about replicating the middle click to frame all that works in Nuke, but in Houdini network pane. Middle click drag would still pan, but just middle click would frame your nodes. I've been searching for this but couldn't find anything yet.... Also would you mind detailing a bit how you went about adding to the Houdini interface the project and scene widgets you have there on top ? They seem prety neat ! I'll join your website community in case you talk about those there and I've missed it. Thanks for the videos !

thanks for the lesson. What Linux are you using ?

[nicholaspfeiffer]

Are you running Linux? I'm curious how you customized your UI so much
