With The Cycles render engine you have more than 77 material nodes at your disposal. Who could possibly remember them all? Well, you can, with the help of this book.
The Cycles Encyclopedia is an in-depth book covering all nodes and settings of the Cycles render engine. It is a professional documentation project by the Blender experts Frederik Steinmetz & Gottfried Hofmann, both Blender Foundation Certified Trainers.
- New, version 1.4! English, German and French versions
- Detailed explanation of every(!) node and setting in Cycles
- Graphics and drawings explaining how the nodes work internally
- Pre-rendered comparisons of node settings
- Bonus chapters on render performance, camera settings and Python snippets to use with Cycles
- Find out how a path tracer works internally and how use that knowledge to your advantage
- eBook in PDF and ePub format (283 pages A4 for the PDF) – compatible with all e-reader devices, smartphones and tablets.
To get a an overview of how changing a setting in Cycles will alter the look of a shader the book includes several comparison sheets, at least one per shader. Here is an example for the glass shader:
To help you understand how Cycles shaders work internally The Cycles Encyclopedia has drawings included to visualize what is going on behind the scenes, here an example for the ambient occlusion shader:
The Cycles Encyclopedia also includes many hints and tips on how to use shaders and other Cycles features. The ambient occlusion distance for example should be about half of the ceiling height for interiors for perfect results:
Ambient Occlusion (AO) is great for clay renderings. Using the material override option for render layers, an entire scene can be rendered just with AO. For interiors, using a value of half the ceiling height results in perfectly smooth gradients along the walls and all objects (left). When the AO distance is set too low, large parts of the image will be bleached out with no depth (right).
But also the more technical aspects of Cycles are explained using drawings, like the feature sample all direct in branched path tracing:
Author Frederik Steinmetz about The Cycles Enyclopedia: I had no idea Cycles really was this powerful!
Every once in a while I needed to look up something. I had to go online, search for it and if it was something fairly special, it took me forever to find it.
So I was longing for an ultimate guide that has ALL the information I need in ONE place.
That is when I started to do my own research, and I found out so much more than I was looking for! So I decided to write down my findings. Pretty soon the collection started to grow, and it became the book you can see here.
While the work was progressing, my partner and now co-author – Gottfried Hofmann – mentioned: Why only include all the material nodes, why not include EVERYTHING? Which was when we teamed up on this project and it now includes camera settings, render settings, the node wrangler addon and much more.
My work greatly benefited from all the knowledge in this book and so can yours! Not convinced? Try it out, if you are not completely satisfied, let us know and get your money back, no questions asked.
Co-Author Gottfried Hofmann about The Cycles Encyclopedia: I use this book regularly in production.
When Frederik showed me the first preview version it was immediately clear to me: This book is über-useful. I am doing a lot of training und consulting and having all the information about Cycles available at one place really helps when troubleshooting or optimizing shaders. Since then I am keeping the book with me all the time. I also joined forces to add all my theoretic knowledge about Cycles and path tracing.
So the book now works on three levels:
- A place to look up all about every node and setting in Cycles.
- A reference sheet for the look of shaders and textures.
- A guide to path tracers in general.
We hope you will find the book useful and will enjoy reading it!
