To my awesome mom and dad, for giving me the advantage and opportunity to succeed. To my two
best mentors, MJ Demarco and Jim Rohn, who opened my eyes, guided me, and are still guiding me
throughout my entrepreneurial journey.

Foreword
In 2019, I found a course called Learn to Create Photorealistic Exterior Environments, by Abdelilah
Hamdani. That was one of the courses that changed my life. Back then, I didn’t know much about
Blender and from that course, I learned what was needed to create a good-looking photorealistic scene.
With 3D Environment Design with Blender, you will have a better experience than I had in 2019
because this book will take your learning process even further, showing step by step what you need
to do to make your scene realistic – for example, matching a Blender scene to a real-world scale and
how to make a photorealistic material. Those subjects are easily overlooked by beginners and even
more advanced 3D artists, making it difficult to realize why your scene doesn’t look good.
You will also take a dive into how to create UV mapping and nature assets (plants, flowers, and rocks)
and how to scatter them; landscapes, realistic rivers, procedural good-looking materials and how to
apply them; photorealistic lighting and rendering; and finally, compositing. In summary, everything
you need to create a complete and beautiful realistic scene.
Everything is explained in detail and whenever possible, examples from daily life are given to make
it even easier to understand some concepts.
Reading 3D Environment Design with Blender, you will have a complete journey from start to finish, very
well explained. You won’t get confused because the chapters have a connection, meaning everything
makes sense. You will just need to follow it through to the end and you will come out a better artist.
I can say that my first contact with Abdelilah Hamdani’s course back in 2019 changed my life because
today I make a living with Blender products – something I didn’t think would be possible. This book
could be your first step too, to help you start making a living with Blender.
