If the class is too advanced, no need to worry! I have several other and more beginner friendly classes for Cinema 4D on my profile, one of which is a complete masterclass aimed at absolute beginners and people who have never opened the software before.
Remember to share a screen with your question which will make it easier to understand the question! If you get suck on any part of the class, you can ask your question under the class and I will answer your question as soon as possible. The class is probably more suitable for intermediate to advanced users buts its also detailed enough that beginners should be able to follow along without too many problems either.
In addition to learning the full step by step process of creating this scene in particular you will also learn several general techniques, tips & tricks to working with Cinema 4D & Redshift Render. In this class, you will learn how to create a floating astronaut scene in Cinema 4D and render it with Redshift Render, the GPU based Render Engine for Cinema 4D.
