Description

Note this is an INTERMEDIATE LEVEL course. 

Blender is an industry-strength 3D-modelling suite, with huge potential for automation using Python. Unfortunately getting setup, and writing Python code to script Blender can be hard.

This course makes it easy to program Blender with Python. By the end you will have a professional working environment that will allow you to rapidly iterate Python code.

If you have never coded before, or you have no Blender experience then this course isn't for you yet. Check-out one of our other beginner courses. If you have some coding experience, and something you want to automate in Blender this course is ideal for you.

Maybe you think it's not worth the time and effort to automate, why not just pay somebody or manually create what you want? Here are three top reasons this is worth your time..

  • Learn how Blender works behind the scenes.
  • Gain confidence in your Python coding.
  • Create realtime automation that can't be done manually.

With over 120,000 happy students here on Udemy, and some of the highest ratings on the platform, we're confident you'll be happy with your investment.

Here are the steps you'll learn how to...

  1. Run and reload Python code in Blender.
  2. Use fast C-libraries such as Pillow.
  3. Duplicate and place 1000s of 3D objects.
  4. Manipulate Blender's data structures.
  5. Change materials including nodes programmatically.

What could you create if you could automate anything in Blender?

Take this course now and find out :-)

Who is the target audience?
  • This course is designed for people with enough prior experience in Python to define functions, write loops, understand dictionaries, use list & handle files. The Python we write will be explained but not from first principles. If you've never coded before this course isn't for you.
  • You will need some familiarity with Blender, particularly its interface and manipulation of basic objects. If you have never used Blender before we suggest you take the first few sections of our Complete Blender Creator course first.
  • If you want to apply your existing Python knowledge to the automation of Blender this course is for you.
  • If you want to automate your workflow in Blender, and are willing or able to code in Python, this course is for you.

Best-selling Instructor, Game Developer, Online Entrepreneur

Hi, I'm Ben. I have a degree in computing from Imperial College London, and a physics diploma from the Open University.

I started working for myself at the age of 15, and never looked back. I explored careers as varied as being a commercial pilot, stunt-man, rock climbing instructor, and more. None of these provided a continued challenge, and stable income in the same way technology does.

After building and selling a home computer support business, I became an angel investor and business mentor here in Cambridge UK. I fell in love with teaching game development through one of my investments, and I now spend all of my time sharing my passion with people like you.

I can't wait to help you experience the fulfilment, and financial freedom, that having a deep understanding of technology brings.

So why not start learning to make games with me and my team now?

See you soon!

Ben

Technology Teacher

I am a self confessed technology geek, and love teaching people new things.

I think it is a real shame that so many people carry around such wonderfully capable devices yet do nothing but the basics on them. Computers, laptops tablets and smart phones can do much more than most people know. I would like to guide, reassure and educate people in using their technology to add to their lives

I have been playing, yes playing, with technology for as long as I can remember and I still do that today! Admittedly these days with other commitments I do have to watch what I spend as technology can burn a very deep hole and quickly!

As my parents will testify, I have always been inquisitive! even if it meant taking something apart to see how it worked. Of course not knowing how to put it back together again! To this day I love learning new things and developing myself as a person.

Despite my techy background I remain firmly grounded and talk to people using every day language, unnecessary techno-babble drives me bonkers. This allows me to chat with people with limited knowledge on a subject and help them understand more.

By day (and sometimes night) I run a successful local technology support company in Nottingham (UK).
