( THOMAS M. GRIMES - OFFICIAL marketing Specialist of Chaos Czech )

Despite delays due to snow, it finally arrived! It’s amazing how every page is PACKED with information and detail – no space is wasted, and the book is so complete that despite getting right to the point on every topic, it’s still huge! Heck, there’s even 11 pages on the Corona Fractal. and that’s just one of the “for fun” things, so you can imagine the info on the functionalities you use every day.

( ANDER ALENCAR - Founder and CEO at Oficina3D )

I loved this complete Corona guide by Francesco Legrenzi. It has illustrations and text about every detail.  I found it very complete, showing every detail of the software with both text and illustrations, making it much easier to understand the operation of this incredible tool. Congratulations, Francesco, on creating this work. Very helpful 👏👏👏!

( MARCIN MIOTEK - Head of Chaos Czech tech support )

Knowing Francesco personally, I was one of the few lucky ones who actually knew that he was working on a book. I even helped Francesco by sharing my professional knowledge of Corona, but I never knew what exactly the final product would look like.

The end result has definitely exceeded my expectations, and I am sure not only mine! Francesco has put an insane amount of time and effort into creating his “Corona: THE COMPLETE” book. Actually, it is not only the book, but also various 3D content: scenes, materials, models, and more, which combines into the most comprehensive Corona guide ever printed.

I can honestly recommend this guide to any Corona user (be they a beginner or a professional), and to anyone interested in 3D graphics!

( RUSSELL TRAILL - OFFICIAL marketing specialist of Chaos Czech )

The first thing you will notice when receiving this book is how high quality the finish is, from the beautiful glossy cover to the pages themselves.

But the book is not only great to hold! It’s packed full of example scenes and detailed explanations. If you’ve ever wondered how something in Corona works, wonder no more – buy the book!

Francesco Legrenzi’s book is without a doubt the best guide we can find for Corona. It’s curious when you think you know everything and realize you still have a lot to learn. Very interesting reading.

( CLAUDIO "NAXOS" GALLEGO - 3D teacher - 3D maker - 3D anthousiast since Amiga500 )

More than a decade ago, I bought Francesco’s first book: “V-Ray: THE COMPLETE GUIDE”. For years it became sort of a bible, or let’s say… my bedside book, the book used each time I needed any technical information about V-Ray. I’ve been teaching V-Ray for about 10 years, and this book is really precious to me.

Then I fell in love with Corona, when working with friends on a big theme park project. So, I moved my production to Corona, and never went back. I’ve been to Prague to become a “primary instructor” at Render Legion’s (Chaos Czech) headquarters, where we received a big technical book full of information.

However, I was secretively waiting for a miracle, saying to friends that I’d like a “COMPLETE GUIDE” on Corona, like I had for V-Ray, with a scientific-approach and all parameters explained and tested. Francesco has made this dream come true, and this will become Corona’s bedside book / BIBLE. Somewhere you can search for any answer, and to recap all that is important when using Corona.

Thank you Francesco, great job! Don’t forget to write add-ons when new features will be released.

( OZAN CAKINZ - Creative executive Wonderland-Architecture )

I think, in my career, I was very lucky to be surrounded by amazing people who helped me. Sometimes it was a small push that was needed, sometimes it was a bit more. Nevertheless, it was something I really found helpful, and I am incredibly grateful for.

Francesco is one of these people. I had no idea how hungry I was for his book until I opened the first page. Before I knew it, I was caught up in the pages. It’s incredible to see how such a great artist uses his toolset.

I believe that with hard work any one of us can become an amazing artist. Einstein said: “Creativity is intelligence having fun”. With this book, you will have access to many tools so your creativity can blossom, and you can become the best version of yourself. My sincere and grateful appreciation for your amazing work! Your book is an eyeopener and a stepping-stone to the next level! Best purchase for knowledge so far!

Grazie mille, Francesco, you are officially one of my heroes!

( FEDERICO SCHINTU - Student at the Faculty of Architecture )

Finally, a Guide for Corona Renderer with a capital G. Every parameter is fully explained, and every aspect has been thoroughly explored, for total knowledge and mastery of this rendering engine. It’s all accompanied by images and practical exercises to clarify every single tool. You can feel the incredible amount of research behind this manual.

I recommend this guide to all Computer Graphics enthusiasts! Chaos Corona THE COMPLETE GUIDE testimonials

Chaos Corona: THE COMPLETE GUIDE - testimonials 04
( SAMUELE STEMERRA - Architectural Designer )

Since I became interested in Corona in the middle of my university career, I’ve always wondered why no guide was available to give newbie users the possibility to train with this engine. It is difficult not to get lost among the hundreds of tutorials on the net. Yes, often these video tutorials get you the desired result, but they create great confusion and leave you with important learning gaps, as well as being repetitive and not very thorough.

When the announcement of this guide appeared to me on IG, 10 minutes later I had bought it. Unlike many other dedicated guides, video courses, and software for architects on the market, this book can truly be defined as a COMPLETE GUIDE, with great attention to every detail, both conceptual and graphic, and it is a pleasure just to have it in my hands. While Francesco was working on his guide, I became a certified user of Corona.

I would recommend this guide especially to experienced users who want to improve and learn everything about this engine. My only suggestion to fully enjoy this book is a deep knowledge of 3ds Max.

Thank you, Francesco, for your dedication!

Chaos Corona: THE COMPLETE GUIDE - testimonials 05
( ERNESTO DI GREGORIO - Founder & CEO at CAD Service )

Years ago, I decided to switch from Mental Ray to V-Ray. I chose the guide for V-Ray written by Francesco Legrenzi because I needed a more technical approach, and I must say I found the answer to all my questions. Of course, it was a “heavy brick”, and its study was a considerable effort, but I was fully rewarded.

After many years and long debates and discussion on “V-Ray vs Corona”, I gradually decided to leave V-Ray for Corona last year. Even though Corona is a much more intuitive engine, many things were unclear to me. I have read a lot online, even paid for courses, but I’ve never been completely satisfied.

I immediately ordered the book for Corona when Francesco announced it because I was sure it would have all the answers to my questions. When the book arrived, I could have easily skipped many chapters and focused on aspects that were unclear to me. However, I decided to start reading the manual from the first page, and, as I continued reading, I discovered that I had missed many important topics. Compared to V-Ray: THE COMPLETE GUIDE, this book is lighter – it is a guide for everyone, from newbies users to professionals who have been using Corona in production for a long time and want to perfect some highly specialized aspects.

My advice is to purchase Corona: THE COMPLETE GUIDE without a second thought.

( EMILIO SEGHEZZI - Planner and interior designer )

This is the guide I was waiting for to deepen the potential of this amazing rendering engine.

Having purchased Francesco’s V-Ray: THE COMPLETE GUIDE, I was already sure of the accuracy and clarity of the information in this new guide. After reading it, I can confirm this impression. I recommend this book to all users already experienced in 3ds Max, who are interested in gaining greater control in the use of the software, optimizing the workflow, and improving the quality of their projects.

( ANDREA CALZAFERRI - Interior designer )

What to say! Fantastic product!!!

Compared to the usual, repetitive courses (even paid one) that superficially explain how to produce renders with Corona, and that are often of dubious origin, Corona: THE COMPLETE GUIDE is the real, genuine manual for this fantastic rendering engine. All parameters (really, all) are explained in a clear and technical way without leaving anything to chance, allowing the reader to learn how to master Corona. Knowing Francesco and his previous work (V-Ray: THE COMPLETE GUIDE) this was what I expected: you impressed me again!

The quality of the printed book with its countless explanatory images is excellent. Attached to the guide there is also more than 20 GB of digital material (.max files, textures, videos, simulations, etc.) which help the reader to better understand the concepts explained. Carrying out the exercises of the book and following the Francesco’s explanations is a very effective learning method.

What to say more? I never saw such a comprehensive book at a truly affordable price.

Thank you Francesco

( SIMONE PELLEGRINI - CG Artist - Interior designer )

I bought this book even though I’ve been using Corona for four years. I have never taken any courses. I learned everything through the web, although I always hoped for a real guide like this, which could guide me step-by-step and allow me to understand the differences between the various settings and parameters.

Even after the first few pages, I am able to make improvements to my scenes thanks to the lessons learned from this book, and am noticing significant progress! I finally found a real manual with everything useful for my projects.

You guys did a wonderful job. So – really – congratulations!
Chaos Corona THE COMPLETE GUIDE testimonials

( FRANCESCO SCARPELLI - Building-Architecture Engineer )

I reserved the guide as soon as I heard it was being printed. I think I was one of the first to receive it, and I have to be honest: I was amazed! It deals with all the necessary topics and it clearly states how the program works, even to the most inexperienced.

Before, I used to play with the various parameters, if I may say so, “by feeling”. After reading your guide, now I know exactly what I’m doing, and above all, why!
This is a tip to new Corona users or more experienced professionals: the guide is really well done and is a unique piece of art!

Thank you very much, Francesco, for your work.

As a Mac and Cinema 4D user, Corona is the best solution for working subtly and efficiently on larger projects. I got on with Corona very quickly.

Now with Francesco’s book, I have a reference book that answers all my questions. The book is very informative and full of details. Even though the book was written for 3ds Max, as a Cinema 4D user you will quickly find your way around.

My compliments – all manuals should be like this!

( ALEXANDER FROLOV - Photographer for business, 3D artist for passion )
I’m 36 and I come from Russia. Recently I got your book, and the truth is I’m still amazed at how good and well-structured it is. Firstly, I wanted to deepen my knowledge on several specific topics, but then I realized that almost every page contains something new for me, and that these bits of information are really crucial. Even now, after one week of reading, I see my work skills improving. What will happen after I finish the whole book? =) I feel so proud and happy to have a book written by somebody who took the responsibility of creating a manual for 3D artists from all over the world. I hope that you won’t stop at this and will update the book as the new versions of the apps are released. This is a ton of work. Thank you!

The Holy Bible of Corona Render. High-quality images, examples, and ready files to use and practice. You will improve your knowledge and skill. “Corona: THE COMPLETE GUIDE” will lead you into the next skill step. You will find detailed and precise knowledge on every parameter. It’s not a simple book – it’s a manual to use with every project you have.

Thanks, Francesco!

I am a Peruvian architect based in Germany. I have been in the world of 3d modeling and visualization for more than 10 years. A few months ago I started to be interested in Corona due to the potential of the program, but I encountered many difficulties in trying to understand one hundred percent of this tool.

Discovering this book by Legrenzi Studio has marked a before and after in my training as a 3d artist. All my questions and doubts were answered in a masterful way by this unmissable book.

I received the book today. Thank you, Francesco. There is no limit to my happiness 🙂.  The book gives me a lot of inspiration, and I am sure that, after reading it, the level of my work will increase significantly. So much useful information! Wow:)

Chaos Corona: THE COMPLETE GUIDE - Testimonial - Dusan
( DUSAN VUKCEVIC - Freelancer, 3D artist and musician )

I learned a lot from V-Ray: THE COMPLETE GUIDE, so buying this book was a no-brainer. Corona is easy to learn and to use, however I found a lot of useful things in this book that will help me with my projects. I love it when I learn something new, no matter how small. Those small things often turn out to be big in the long run.

Francesco explains everything in such detail. It’s rare to see this level of effort and dedication these days. Superb book quality. It’s really nice to skim through the pages and look for the hidden gems of this amazing renderer.

Do yourself a favor and buy this book.

Chaos Corona: THE COMPLETE GUIDE - Testimonial - Francesca
( FRANCESCA IMPERIALI - Designer and 3D artist )

I met Francesco fifteen years ago. We were colleagues in a design studio for a long time, and I approached the world of rendering thanks to him. I immediately thought he was “as crazy as a horse” 😉 but also a little genius (at the time he explained V-Ray to me), and immediately I became passionate about 3D graphics.

The guide is like him: very precise in every aspect. The book leaves nothing to chance – it is very clear and comprehensive.  I would define this as his best render.

For people like me who want to switch from V-Ray to Corona, this book is the turning point. I recommend it to everyone.

( GorkStudio )

Today we’ve received our copy of “Corona: THE COMPLETE GUIDE” – a unique edition which includes analysis of everything that is in this render engine.⠀
Actually, Corona is a relatively simple tool, but even after just flipping through this book you can immediately find a couple of unclosed gestalts on some topic which you haven’t already worked with.

It is also very convenient in training new people. It seems to be nostalgic when flipping through it, as with a student textbook of the early noughties.

Chaos Corona: THE COMPLETE GUIDE - Testimonial - Ivan
( IVAN DE CARO - Architect )

Invaluable tool for an accurate knowledge of Corona . This book will allow you to deepen your knowledge of all the necessary topics, to manage the scenes created with Corona and to produce quality renders. I recommend “Corona: THE COMPLETE GUIDE” to anyone who already has experience with Corona : you will surely find something new to learn and explore. Also, newbies will finally have an excellent starting point for their studies.

Compliments for the print quality and for the concreteness of the contents.

Since I started my involvement with Corona 2 years ago, I was looking for a guide. Finally, I found this one: Corona: THE COMPLETE GUIDE.

( JOAO PEREIRA - 3D artist at PressRender )

“Corona: THE COMPLETE GUIDE” is, without a doubt, the best book. It’s incredibly detailed and well-produced. The quality of the content and details are some of the best I’ve seen to-date, if not the best. All, absolutely all of the features of Corona are available in this book. No matter how many questions you have, just look a little in the book to find a solution for what you’re looking for. I recommend it to all artists, whether they are starting now or already have a stable career.

May THE COMPLETE GUIDE be with you! Corona THE COMPLETE GUIDE testimonials

Chaos Corona: THE COMPLETE GUIDE - Testimonial - John
( JOHN RANKIN - retired from Aerospace )

This is an amazing book! High-quality printing, well-designed chapters, and colorful examples. Corona Volume Grid is covered extensively in 21 pages with detailed explanations. So much better than web tutorials. I am a 3DS and MAX user since the 1991 initial release and have used a succession of renderers: MR, V-Ray, Redshift, and now Corona Renderer. This is by far the most intuitive, and with this book, a real time saver.

Thank you, Francesco. Congratulations!

P.S. I purchased the guide in March and waited for it to arrive, only to eventually find that the postal service, USPS, had lost it in NY. Francesco graciously sent a replacement. He is the best!

( SALVO MACCARRONE - Visual & Models Designer at Eyecad VR )

Page after page, the immediacy and expertise of this book will overwhelm you. Excellent – couldn’t recommend it more highly.

Scrolling through the pages, you can immediately feel the energy and years of work spent on this guide. Thanks to its simple and immediate language, even an average user will be able to make the most of the Corona tools. The numerous files inside the DVDs allow you to better understand the chapters of the guide, involving the user in a comprehensive and rewarding learning experience.

Even the most experienced professionals will be able, thanks to this guide, to refine their techniques, speeding up many processes long taken for granted.

The collaboration between Legrenzi and Chaos Czech has created a very high-quality product. I absolutely recommend it!

Corona: THE COMPLETE GUIDE is the Bible for us in pics.com.ar. The book is very well detailed in its explanations of each problem. All 3D artists that work with Corona should have one copy of this book.

The book is very well produced and explained in high detail. Here in the studio, everyone is using the book to clarify things they didn’t understand.

Thanks a lot, Francesco, and congratulations!

Wonderful job, Francesco!

Chaos Corona: THE COMPLETE GUIDE - Testimonial - Ragu
( RAGHU MEENA - Rag3DViz.com founder )

I’d read “V-Ray: THE COMPLETE GUIDE” thoroughly in the past, which was an amazing reference and certainly helped in clarifying things. I hoped this book would be of the same caliber of information. Certainly, it did deliver.

I wholeheartedly recommend this book to whom so ever wants to clarify their Corona concepts and build a solid foundation with the software. Mastering basic and fundamental knowledge is the best way to move forward, rather than copyng and following some tutorial over the internet.

Thanks, Francesco, for your wonderful work. The whole 3D community should be grateful to you.

Chaos Corona: THE COMPLETE GUIDE - Testimonial - Raffaella
( RAFFAELLA RICTER - 3D artist and interior designer )

The book is fantastic. It explains in detail all the parameters, materials, and everything you need to achieve professional renders. It consists of numerous illustrations (more than three thousand) showing the Corona parameters set with incremental values. Legrenzi’s method helps a lot to understand in advance what happens when you change the Corona settings. Finally, you can also combine theory and practice by following the countless tutorials in the book.

I recommend this guide wholeheartedly!
