Hi R.,

This is a general question that may address your individual needs. I would love to know more about your targets. What do you want to do?
Given the gap between version 17 and 2026, I presume it is a good idea to get an overview first, with "What's New" videos for now. Which I think is a great start to forming a good idea about the options given now and where to go next. I'm happy to help.

We also have a lot of YouTube content, often sorted into playlists.

To get the latest updates, you might share a lot of things that don't match your interests, as the variety of tools and functions is vast. What is your main field? What level do you need the "update" content, and what is typically your learning style? Fast, quick information chunks, and then start exploring on your own, or detailed courses, guiding you from A-Z?

Here is the Training team's YouTube channel, with a search set up for Redshift:

OR the Maxon One YouTube channel set up with a search of "new in Cinema 4D

Rocket Lasso is a great source with lots of creative examples for new features:

Which is perhaps also an intense way to catch up.

I suppose that will give you a good idea about the new items from the past few years.

Perhaps School of Motion is a good fit.

Please let me know if you have any specific areas you'd like to explore in more depth.

Let me know how some of these worked for you, and I'm happy to take a deeper look

Enjoy the new features, and please let me know more about waht you like to do with the new features! 🙂
