This is a great series of training videos. Easy to follow along and clear cut instruction. Highly recommend!

Just purchased your tutorials. Really love your teaching style, the methodical nature of how you go about breaking things down in depth and your general warm tone for all videos. Well done good sir.

A must for anyone using/new to octane - you’ve done a great job on this @epicjcreations  i like the short video format and organization of content is easy follow and refer back to when needed, easy scrub and skip to relevant bits. Many tutorial series are not as well organised. (This is not a paid promotion!)

best available course for octane in the whole net. waited years to find a course also made for advanced users... epic work! 

For me as a 3D artist doing his passion for his living, the course from John is a kind of fundamental knowledge base. Every button and every single function is explained in wonderful way and perfect structure. A MUST HAVE course for beginners and pros!

I’ve managed to find time to get through about half of the first ‘chapter’ of the course.  So far I give the course a five-star rating.  You are a great teacher.  I’m new to Octane, and it feels like you are giving just enough information in each segment for me to learn new ideas, but not so much that I would feel overwhelmed

This is by far the best tutorial I've ever watched. So clear and understandable.

This is the epitome of a perfect tutorial. Explained everything, no unnecessary information, great tempo! Can't wait to check out your other stuff sir.

Dude, I loved every second of your video. Finally someone who understands how to convey knowledge and what problems can arise in understanding. I have to tell you that you really have talent for teaching.

Wow, amazing tutorial. You speak like a radio announcer, without mistake or pause. My native language is not English, but I understood everything you said in this best tutorial I've ever seen about Octane. Cool! Unfortunately, I only can give one thumbs up. Awesome presentation, I will see all your videos, thanks!

John, just wanna say that this video, among the many others you have made, has been very informative and helpful in teaching me a new skill and also furthering my understanding of basic core concepts of textures/materials inside of Cinema 4D and Octane. 

Seriously, thank you so much for committing the time which you do to these tutorial videos. I've been doing 3D related stuff for about a year, totally self taught, so when I'm able to find someone who puts out quality orientated content, it really means a lot and makes such a world of difference in my own personal learning.
