Hello there! I am new to houdini and watching tutorials that everyone recommends, I see that they use version 16.5 mostly. Since the apprentice version is limited to using the latest version, how difficult will it be to follow those tutorials for an absolute beginner like me? I have always been afraid to learn this program because of its reputation for being difficult, but lately I have thought that procedural modeling would make my life much easier, and before I buy an indie version, I would like to learn the basics perfectly. What happens is that I am afraid of not being able to follow the tutorials correctly because of this difference in versions. I hope to learn a lot, and that in the future I can be of help to people in my situation right now!

You are in luck, since tutorials below H16 have a weird fixation on using pointsop. It was not fantastic.
Also, I personally have an introductory series that are up to date and well structured (because I care).

Hey! thank you very much for the response! I will be looking forward to watching your videos. The truth is that I have been following a course from udemy and it has taken away (most of) my fear of houdini. That said, I'll get right on it with your videos. Thanks a lot!

I think the tutorial creators owe to the community to update their tutos, especially if they are commercial, but sometimes it can take quite a lot of time depending on the magnitude of the changes

I've had the same issue. I've ended up just looking up the differences between the old nodes they're using, and the new ones, and that's helped me a bunch. However it'd be GREAT if they updated their videos, especially ESPECIALLY if they're selling them.

I believe Rohan Dalvi is doing just that with his pay tutorials
