HUMAN: Realistic Portrait Creation | More Info
DISLCAIMER: This post is a long one. A) because 2 years is a long time to dwell on a course and what it means to me. I hope you don't mind the personal transparency along with the important info! And B) this thread is becoming a catch-all of FAQ's that are spread across various places.
First I want to thank you, the CG Cookie community, for your patience with me and the extremely lengthy production of the HUMAN course. This project has been my primary passion for two years. It’s been a very different endeavor than our modus operandi, and I’m deeply honored by the sentiments from many of you that the wait will be worth it 🧡
I’ve put everything I have into ensuring you’re right! I’ve never spent more than 4 months on a course. So you can imagine what 2 years can do for scope and depth. I promise two years was NOT me being lazy. I’ve never dug so deep into a topic before, never R&D’d so much, and never rehearsed techniques so thoroughly as I have with HUMAN.
I know there’s a lot of aspiring character artists in this community like me: Obsessed with crossing the uncanny value into compelling, photorealistic, entirely believable 3D characters. This course is my magnum opus on the subject. I truly cannot wait to share it with you and see what you all create out of this curriculum!
“OK but...what is HUMAN again?”
I’ve been openly discussing this course in livestreams and comments around this website since 2019, along with a blog article blurb, but I can only assume there’s some (maybe many) of you that don’t know about it.Please allow me to give some background:
My first tutorial course back in 2011 was also about portraits. As my first course, its quality isn’t great...OK it makes me cringe. It’s long overdue for a re-record. Coming back to the topic after all these years is a return-to-form for me; even sentimental in a way. Almost like a rebirth as an educator.
That is one reason I wanted to go BIG on HUMAN. Another reason for going BIG is that our usual course production time of 1-4 months is very limited in terms of depth that can be taught. Over my 8 years with CG Cookie there’s a lot of advanced course ideas that have built up with no way of being made in 1-4 months.
Then I witnessed Gleb and Aidy’s Space VFX course followed by their Hard Surface modeling course. I was utterly inspired by their quality and depth, wondering “how can they do this?!” Then I realized how much time they spent in production between course releases.
Time is the true economy after all. Depth and quality require significant time. So I pitched the idea to Wes for spending 1 year making a “mega” course. 2 years later HUMAN is here! 😅
Things to know about course availability
CGCOOKIE.COM is THE place to access our entire course library including HUMAN. We are also offering it as standalone purchases on the Blender Market. We’ve been doing this for years as it’s commonly requested by those not interested in subscribing. You may have noticed that the course is available for Pre-sale on the market from now till release. So what does this mean for Citizens?
All active Citizen members will have access to HUMAN on November 23rd. The Blender Market pre-sale is irrelevant as long as your subscription is active. BM customers get anAtomic and the 3 final portrait .blend files as a little something for pre-ordering. Likewise we’ve made those assets available to members on the Resources page. Get ‘em while they’re hot!
There’s also a bundle option for pre-sale on the BM that includes 6 pre-requisite courses to prepare students for HUMAN. All of these courses are available now to active members as well 👇
I want to first say that I maintained a firm goal through the course's production to be inclusive of all experience levels. Even though it’s a very advanced subject, I still think beginners can and should be able to engage with it effectively. Many portrait courses (my first one included) assume the viewer knows a lot. Really to the point that only advanced artists know how to apply the information. I’m proud to say I was resolute to assume as little as possible. Hence the 25+ hours of video 😅
That said, I still think it’s wise to offer prerequisite courses to best prepare for HUMAN. Especially if you’re brand new to Blender or switching from another 3D app, these courses will familiarize you with foundational concepts and skills that portrait creation builds upon:
- Blender Basics: CGC’s singular starting point for all Blender beginners.
- Fundamentals of Digital Sculpting: Essential concepts for forming 3D organic shapes artistically, comparable to traditional clay methods. A fundamental understanding of sculpting with Blender is important for beginning chapter 1 strong.
- Fundamentals of Mesh Modeling: Essential concepts for polygonal mesh modeling. This relates to retopology, mesh structure concepts, and modeling for the portrait’s glasses in chapter 2.
- Fundamentals of Texturing: Essential concepts like UV-unwrapping, image textures, and procedural textures. This is especially relevant to chapter 3.
- Fundamentals of Materials & Shading: Essential concepts for material creation and rendering. This is especially relevant to chapter 3.
- Fundamentals of Digital Lighting: Essential concepts for lighting and rendering. This is especially relevant to Chapter 5.
If you're a member and interested in learning from HUMAN, go ahead and start watching these courses if you haven't already!
Recommendation for learning from HUMAN
There’s no sugar-coating it: Achieving realistic portrait results is extremely difficult. Even after 17 years of experience I’m not perfect at it. And I’d argue that no one actually is - not even the best of the best. But every portrait project teaches us new things and refines our process significantly. This challenge and perpetual education is what makes it such a rewarding pursuit!
There’s one key recommendation I want to offer you to ensure best educational results: Please do so patiently! Take your time watching and applying the same way I took my time teaching it. That’s right: If you’re not still watching this course 24 months later you’re doing it wrong.
No no, of course not! All I mean is please don’t expect to watch it through once as a long list of step-by-step instructions that will produce the exact same result from the videos. As with any complex art form and craft, patience in learning and practice is the key to success. And I desperately want to witness the fruits of your success!
Specifically I recommend watching through the whole course once casually; no Blender open and maybe not even at a desk. Do it on your couch with popcorn at 1.5-2x speed. The reason for this casual watch is for you to get a bird’s-eye-view of the complete workflow before attempting to follow along. Seeing the big picture first will give much-needed context to the plethora of small tasks and techniques.
After your initial viewing, I recommend practicing each chapter by itself at least twice before going to the next. So for chapter 1 you should sculpt at least 2 heads from scratch. For chapter 2 retopo and detail two separate times, etc. The unfortunate (or fortunate?) rule of practice is that the second attempt is always better than the first, third is better than the second, etc. Trust me I struggle with this rule. BUT I only have experience that proves it to be true. The more you practice each chapter the better your final result and the longer-lasting your education will be.
For more info please check the Blender Market FAQ page.
Are the techniques taught in this course applicable for rigging and animation?
To be clear, the end goal of this course is static portraits. BUT the techniques are definitely conducive to rigging and animation. The second chapter covers retopology (for optimizing our sculpture and preparing it for high-poly detail sculpting) where the mesh structure is deformation-friendly.
Most of my professional experience leans toward animation so I rarely teach something that can't work that way. The only major components not taught in the course are teeth and a tongue.
What kind of head should I create?
This question is a fun one. If you’re interested in HUMAN you’re probably already imagining the endless possibilities of characters you could create with these skills! So which one do you do first?
It’s a fun question but one without a perfect answer. I’ll answer in two ways: First, of course you can consider matching the kind of head I create in the course. For some it’s more effective for learning to try and match exactly what’s happening in a tutorial course. This is totally fine and valid, especially for first-timers. Personally I would love to see portraits of all ethnicities, genders, facial structures, and hair styles be created out of this course!
Which brings me to my second answer: For those undeterred by one more layer of challenge, I recommend creating a portrait that looks similar to yourself. Not necessarily a self-portrait, because I’d rather avoid the pressure (and potential frustration) of likeness from the beginning. Just someone with similar skin color, complexion, hair type, eye color, etc. The reason being that you can serve as your own reference. Whether you decide to take high res photos of yourself or keep a mirror at your desk, frankly you’re an unlimited resource of ideal nature.
This is why the portrait in the course, whom I’ve named “Colin, looks similar to me: Caucasion man with glasses and short hair. Once we’ve successfully created a portrait that looks similar to ourselves, then we’re better prepared to branch out and achieve portraits of various ethnicities, genders, body types, etc.
A problem with this approach is that not everyone taking the course looks like me. For those that do not, you’ll have to face the potential challenge of translating caucasion-specific techniques to match your own traits. This means there will be some gaps to fill in along the way. It’s very doable for the initiated but it could also slow one’s progress.
Do I need a drawing tablet to follow this course?
Technically you could use a mouse but it would be a challenge. I actually prefer a mouse for brushes like Grab and Snake hook most of the time (for more precise movements). Still a drawing tablet is highly recommended.
I can't say it's 100% required, but the pressure sensitivity and more artistically-inclined mechanics of a tablet make for far more enjoyable experience when sculpting and painting textures.
I wrote an article about tablets on our blog if you want more information.
Do I need a supercomputer to achieve detail like this?
You don’t need a supercomputer but PC specs will make a difference with any high fidelity projects like this. I'm not a hardware expert (even if I was there's way to much hardware variety to say definitively) but in general I recommend a mid-to-high end desktop or high-end laptop for effectively creating portraits of this caliber. In every way we're pushing Blender to its limit from sculpting in the 10's-of-millions of polygons, hi-res texture painting, complex material networks, hundreds of thousands of hair particles, and large 2K Cycles renders. My wife's 2017 MacBook Pro does not do well here.
For reference: My PC used to record this course has the following:
- GeForce RTX 2080
- AMD Ryzen Threadripper 2950X 16-Core Processor (3.50 GHz)
- 32 GB of RAM
Why not just use Metahuman?
Metahuman is a great tool! But it’s for people that want believable digital humans fast and easy. CG portraiture, the art form, is not terribly interested in fast and easy solutions. This course is much more a deep dive into the art form than it is about fast and easy.
Another way to look at it: Metahuman doesn’t produce character artists any more than Guitar Hero produces guitarists. The drum machine has yet to eliminate the drummer. Ikea has not eliminated hand-made furniture. On and on the examples an go. Likewise I don’t expect Metahuman or AI will ever eliminate the art of hand-crafted CG portraiture.
Does the course feature any addons or other software besides Blender?
HUMAN is based 100% on stock Blender. The only addons I used are included with Blender that simply need to be enabled. No Zbrush, no substance, no 3rd party addons. I use Krita briefly as an exercise example and DJV View to playback an image sequence example but neither are required.
Which version of Blender is featured in the course?
6 versions of Blender are featured in this course, from 2.82-2.93. Blender updates rapidly and 2 years is an eternity in Blender dev time. Ideally the whole course would be recorded with a single, most up-to-date version but it's impossible. Even spending a few months recording a course is risky. More than once I've published a course only to have a new Blender version released the week after; sometimes the day after. This is simply the nature of working with and teaching Blender.
I wrote an article about this and recommend 2 ways of dealing with it:
- If software inconsistency seriously hinders your learning process, I recommend using each version of Blender according to the video. Thankfully blender.org maintains download links for all official releases. This hoop to jump through may be a bit annoying but it will essentially make software inconsistency a non-issue.
- So long as you have intermediate familiarity with Blender, you shouldn't have much problem navigating the whole course with the latest version of Blender. Some interface things have changed, some buttons added here and there, but it's nothing a quick google search won't clarify. Every concept taught in this course is not only relevant to all featured Blender versions - they're also relevant to other 3D apps. There's no reason a Maya user couldn't follow this course and learn applicable techniques for their software of choice. 3D apps are just tools and they change often. The concepts transcend tools and time.
Should I understand facial anatomy before watching HUMAN?
Any preparation like this will only help your learning experience. BUT I designed the course to NOT require prerequisite anatomy knowledge. Throughout the course anatomy is highlighted and explained with images and the anAtomic reference model that’s included with the source files.
How do I unzip these source files?
I used 7zip to compress the "HUMAN_source-files" folder and automatically split the archives into 1 GB chunks. We recommend installing 7zip to also unzip them correctly as demonstrated by this GIFs:
