When I say "in 2D it's really easy to animate arms", I just mean in terms of technical issues. There's tons of drawing skills and animation principles in animating 2D characters -- but much of those skills apply to 3D as well, while the technical aspects of animating arms in 3D that I describe in the video don't apply to traditional 2D. I've been a 2D animator my whole life so I know how hard it is! I could have phrased it better, but hopefully you can look past it.
Also, FK and IK mean "forward kinematics" and "inverse kinematics." The full names doesn't really matter to animators, but I wanted to mention it here as I should have at least shown the full definitions somewhere in the video. Sorry!
-25k views and almost 6.5k subs so far!!- WELP that's gonna get progressively more and more outdated, so why don't I just say a big THANK YOU. It's difficult to describe what a week I've had -- I've been reading every comment and It's super encouraging to know that I'm helping people not only learn animation but, to non-animators, understand and appreciate it. Part of my motivation from the start was to reach people who love animation but have never animated and wanted to understand it better, and it's mindblowing how many comments I've received that fit exactly that.
The next few videos will explore some different things (I want to bounce between art, animation, rigging, etc.), but I do plan on doing the next in this "body" series eventually, likely seasonally.
Also, the example girl's name is Gimberly! She's inspired by 80's fitness instructors.
EDIT: Giving more visibility to my notes above. Also, did you know that editing a comment unpins it? I sure didn't!!
Great job and I wish you all the best! 🥳
The only thing that bothered me throughout the video is that the girl (Gimberly, heh) has a Red on her Left side and a Blue on the Right side. Although I started to study animation and rigging only recently, I'm already used to the fact that usually these colors are reversed for the limbs (Left = Blue, Right = Red, Main body = Yellow). Even when I shoot live video references with myself for our animators, I use this logic (I also use fitness bracelets in these colors 😅).
I understand that each team has its own color coding, but is there something behind this decision? Did you do it on purpose or just make it “as usual”?
@@Fortirus Thanks! Good point, I actually don't think I ever realized that. I usually build my rigs with blue/green controls actually, since that's the mGear default in Maya. So I don't tend to associate red/blue with specific sides myself, just a sense of keeping them separated. But I think I remember wanting to have them match the most common association, I do see the "left blue, right red" a lot.
If I had to guess how that happened, when I was designing her, I tend to mirror my artwork often and sometimes the mirrored version becomes the "default" to me. So I imagine I probably designed it with the "correct" colors in mind, but eventually ended up with them mirrored. Since I'm still super early in these videos and I'm going to update Gimberly's rigs anyways, I think I might mirror them and her look in this video will end up an anomaly. Thank you for the suggestion!
this video is absolute proof that you don't need a large amount of subscribers to get views, if you put effort into an interesting video idea, you will almost definitely get some recognition
@@doodley3d oh, thanks for the ansver! Yeah, I also saw the blue/green and green/red coding a few times.
It's funny that although I have never done character design or rigging (with the exception of Control Rig in UE5, but this is different story), for some reason the first thing I thought was that at some stage her design/model was just a mirrored - looks like I was right 😆
And about "fixing" her - I don’t think that it would bother anyone else, and even if so, then you can simply say that this is her feature and character quirk 😏
This comment is so wholesome, you deserve every view and a ton more! What you have made is very helpful even for someone like me who's not trying to focus on animations. Quality content, thank you for this!
Wow what an incredibly high quality tutorial and well produced video. As someone who is clearly unbiased, I think everyone should like, comment, and subscribe to boost it into the algorithm
i know right
Could you post the music made for this video somewhere?
it's really relaxing
@@nozumo3964 Doodley and I actually talked about getting a soundtrack album out recently. Stay tuned for that!
are you okay with others using your music in streams.Wether on yt or twitch?
@@sos3365 I'm pretty chill about people using my music in general, as long as I'm credited and linked
I don't even animate, but this video's presentation was so captivating that I couldn't look away for even a second. Absolutely stunning!
Same
Me too
I agree I love the girl character showing the tutorial off for what you can do also I wonder what's her name? 🤔
Me too and I am cute 😍
@@zippy8250 glimbly
What I like about both of your models is that they feel like they have their own character. You could have just made basic figures and call it a day but you took the time to make both of them emote in a way that make them feel like... people instead of dolls.
YES! Thank you! I thought about creating more robotic or mannequin like figures but personality and emotions affect animation so much, it didn't feel quite right.

Gimberly is so expressive in this animation! What a cutie. Well done on this animation though, it's really helped me out.
i'm a 2d animator, but this video helps a lot with understanding arm movement, even for 2d animators! this video is incredible and high quality, easy to understand! you've earned yourself a new sub :D
Hi KD!
This has an insane amount of effort and its also just... SO NATURAL. Its like youre teaching a class youve taught s thousand times and still love. Unbiased, unfettered, and yet to be topped. This is awesome
What an excellent tutorial my man!! I love how dense it was, all killer no filler and a good enough length to not gloss over important aspects. Looks like this took a ton of work but this is easily one of my favorite videos for studying 3D animation, and I know I’ll be coming back again for references before too long.
i think this is probably the simplest and most intuitive guide ive seen on anything 3d, like, ever. as someone starting out with 3d software (currently using blender) this has made posing and animating a HELL of a lot scarier and easier to wrap my head around
more intuitive and beginner friendly guides like yours are definitely the one thing 3d tools need the most as of now!
I know everyone is saying Blender, but this is incredibly useful for any 3D software in general. You usually only see videos that are specifically catered to one software only, and it makes learning hard if you're using something that isn't popular (like how there are so many Blender videos but so little Maya). So a broad explanation like this on how a 3D mechanic works is a pretty rare to find. I really hope you'll continue to make videos like this, you explained it better than my university professors did!
That's the idea! I use Maya myself and there's definitely a lack of Maya tutorials, but there's tons of core concepts that aren't program specific, so that's exactly what this channel intends to cover. Thank you!
@@doodley3d I’m using maya in school, and one day I forgot how to color and render and I couldn’t find much help that wasn’t cryptic, so everything I made was unfinished

Excellent tutorial on the concepts. Easy to understand and yet goes into a fair bit of depth into how FK and IK differ. As it's far too easy to discard FK in rigs once people know what IK is. Also blended with high quality 3D animation which is both smooth and pleasing to the eye, assisting in visualizing the concepts.
Good work. Approved.

🚨Banger Alert!🚨 It's always a pleasure when youtube finally recommends a high quality video that absolutely deserve more attention. I always wanted to experiment and learn more about 3d for my own stuff so I'm 100% onboard for the rest of the series!
You really be out here animating the part of Gimberly’s body for the tutorial but also going the extra mile and animating every other facet of her being with not just making it all natural and make sense for the action you’re focusing on but with so much extra flair and personality.
I can’t wait for the episode(s) on faces or whatnot so we can hear what kind of voice you manage to get for her! Lip sync is something that always sticks out to me with animation, as the act of talking is one of the most essential yet one of the most potentially boring things to look at, and seeing animators make talking NOT boring is just… *chef’s kiss*
So I can’t wait for that, but even without that she’s so… good! And just a flex of your own skill, as well as how powerful the things you’re explaining can be.
Your own avatar is also cute as all heck, I LOVE characters that talk THROUGH their facial hair like that.

This is the most helpful, well produced, and visually stimulating tutorial I have seen on the internet. I have trouble watching art tutorials because they usually have a static screen or few examples so I get bored but this kept my attention the whole time. You truly are an amazing creator. Also your model is stunning!
David!! This video is so freaking good! I can only imagine how meticulous it’d be to do all of that graphic design animation in tandem with the 3D animation. So freaking good 🙌
ahhh this video is so good, i've been anticipating for a while! 💯 editing, and 💯 music choice (so props to jayfoo!!)
Gimberly trying to free her IK-constrained hand at 1:14 has some horrifying implications
😨
8:13 i love how she reacts
I think you meant 9:13
Amazing video! Her little coordinate frame hair clip is chef’s kiss.
Clear, concise info with very deliberate and well thought out editing. Wish there was more content like this out there. Looking forward to more.
there are some artists and animators who want to do an epic 3D animation that the movies come out and believed that everyone already found a better tutorial and I think many are already learning very good video
3:44 YOU WOT MAYTE
This is a great tutorial! How do you only have 1k views on this? I'm definitely sticking around to see more
it's funny cause I'm a self taught 3d animator, and it took me years to figure these things out in my own work. Had I seen this video, I would have learned all of it in 11 minutes. Using an FK Arm in world space is something I've never tried before, but now I'm gonna be doing that all the time. Thank you for this!
Thanks! It's a brand new video and I didn't post a lot before this one, so these things take time. It's cool to hear your story, I'm also self taught and part of my motivation is to try to think back to when I was first learning and make the tutorials I wanted back then. Thank you again, I hope you enjoy what I have coming next!
Oh fancy seeing you here
hi anomi
As someone who went to school for this stuff in the past, its super refreshing to be able to return and re-learn concepts I missed or might not have gotten a full grasp of before. The content was easy to follow along with and contains really really valuable information for people out there looking to get a start on learning the basic concepts of 3d animations with characters. Thank you, I will be sure to follow and try to keep up!
This is an excellent tutorial that I could recommend to everyone who wants to learn 3D animation.
I started switching to 3D animation recently (by knowing the basics and having animation experience for years)
And I think the FK/IK types were something I was missing, since almost all models I animated yet were on a FK basis, it’s more easier to know that I can switch between the two modes.
Thank You 😊
HOLY CRAP! I never even done 3d rigging of any kind outside of maybe animating 2d puppets on a 3d plane in after effects, but the amount of detail in this tutorial without all the fluff and the flow of the information is so incredibly high quality, I had to give you a sub. Thanks for making such great content!
Excellent demonstrations. Instead of only pointing out examples in professional productions, you had a model to animate your points. She was very well animated, and an adorable character, to boot.
Bro this is incredibly impressive! I’m always saying it’s important to learn both 2D and 3D but with how people are making the tutorial videos. It’s not always easy to understand the rules to follow. This made me have a relaxing learning experience to want to approach character animation in 3D. Thank you! The spark has ignited again 🔥.
I love this video and am also blown away by how cute your explainer character is, i love how much attention to detail you put in and even make the glasses blink! This is so wholesome and i love it!
I'm planning on learning animation, and I feel very happy I discovered this channel. I really love the simplicity, presentation and style in which which you teach, like I'm watching a kids show teaching to animate. It helps nail down the 80/20 rule of this.
Thanks for making this. I'll be subbed to see more if you make any.
As someone who use to play around with MMD and is interested in getting more into 3D animation, I never understood the meaning of IK or FK but this video was such a huge help. Really hope you do more of these in the future!
0:53 Gimberly is way too happy about being able to punch the air

Good news - the algorithm is working! This was SUCH a great video, I've watched it probably three times already just for the animation alone, there's so much passion poured into every movement. I can't wait for your next videos!
The quality you achieved in this video is incredible. Its adorable to see the 3d character reacting to the 2d narrator. Your voice is entertaining and soothing. The music is pleasant. Your script has a nice balance of humor and serious.
The fact that I don’t even animate and I wanted to watch this entire video from start to finish it’s truly a feat. Well done man. I hope you felt like all the work making this video was worth it because I really learned a lot today thanks to you :) makes me appreciate the art so much more.
My guy! Your content’s not only educational and good for learning animation but it feels nice just to watch! Lovin’ these vids!
I wish more tutorials were this good and detailed. This was so incredibly easy to watch, and genuinely enjoyable. Everything felt straight to the point and easy to follow. I also love how bouncy your style looks.
I was struggle with translating emotion into an animation especially when it comes to emotions I don’t react with personally, and knowing how and where the bones should move is such a huge step forward. it was such an awesome video I’m going to watch the rest of your stuff.
Amazing video! Super excited for the rest of the series
I'm a 3D animation student and this video is extremely helpful! I like how it explains the topic in a concise way with simple and easy to understand visuals. I look forward to more of your videos on animation in the future!
Now THIS is how you do a tutorial. Fun and engaging to watch, for both animators and non-animators wanting to watch something new for information or just interested in the topic. Well done, comrade.
The way you show and present everything in such a simple but clear way is amazing, keep making awesome stuff
Loved everything about this video! Immediate subscribe, also loved the way you referenced everything, even the music
Just one bullet
I just realized gimberly is more a "stretchy rig" than a kind of stiff rig and I like it bc it fits a because she was based off those ninteen exercise setions so good job making gimberly
Man! I had never heard of any of the terms mentioned in this video beforehand but you were able to explain them so well without overexplaining them!
so excited to see more videos from you man! they're always so high quality and well done, and even if you arent watching the video to learn how to animate, it's still super entertaining to watch and learn about.
I'm not an animator, and don't particularly plan on ever being one - but your video is absolutely phenomenal even without that drive. You've made something informative, unique, and entertaining and it feels so special, the effort you put in really shines through.
I'm looking forward to the rest of the series!
Nicely visualized and easy to follow along. Great examples too! Thank you for this gem of a class :D
Fantastic video! Your clear and careful definition of terms + constant visualization is perfect for educational content. I'm not an animator but feel much more capable of getting started thanks to just this one vid (the first of yours I've encountered). Thank you!
I normally don't comment on videos, but this was incredibly informative and entertaining! Excited for the future of the series!
I love the sync at 3:53! not sure if it was intentional but little things like these makes videos fun :)
great video!
Totally not intentional but I did notice that in editing too, and it always makes me smile. Glad you noticed too! Thank you!
This channel just came outta nowhere with a banger and I’m all for it. I’d love to start animating in 2D and 3D, and these videos are peaking my interest into getting started. I can’t wait to see more!
I'm blown away by the quality and simplicity of this video. Everything was explained so well and the vibe of the whole video is just so nice and comforting. I love this style and I'm looking forward to your future content!

This is absolutely brilliant. I can't believe you only have 6k subs, this is amazing. Even though I have never 3d animated in my life, I could understand the explanations and the video was interesting the whole way through!! I love the model girl you decided to use to explain the examples, I can see the amount of time and care put into this whole thing. Wonderful job :)

I am learning to model and animate in 3d and this is by far one of the best videos I have stubbled upon to help me understand how to animate a specific body part. I hope to see more from you Doodley, wonderful job!

THANK YOU! Your video format is really nice and you explain everything very clearly, visual examples are such a good addition
Holy shit this is outta nowhere! After the video I went to go check out your backlog and there isn't any!
I can't wait to see what you do next this was great :D
I'm not an animator and probably will never be one, but your videos are so incredibly satisfying. The animation and its pure emotion/expressiveness, the tone of your voice, the art styles.. it's all perfect. To me, you might as well be a master of your craft.
Also, I feel like you could've mentioned what FK and IK means. FK is "forward kinematics" and IK is "Inverse kinematics", two very common mathematic principles in robotics that make it easy to determine what position(and at what velocity) a joint is at
Thank you for the amazing tutorial! I have been wanting to do 3d animation for a while but didn't know where to start. Personally, I think your channel right here is the best option! Keep up the good work! I can't wait for more of your videos!
This is one of the most incredibly well produced videos on any animation related topic that I've ever found. I plan to share it with my college professor, as I think my whole class could benefit from this breakdown. I love it. Thank you!
This video alone has so much effort and passion put into it. I hope you'll have a strength to pull another ones!
All the support in the past week has filled me with IMMENSE STRENGTH, so I'm very motivated!! Thank you for the kind words!
I FREAKING LOVE THIS VIDEO AAAAA
Seriously though, you, Jayfoo and Melanie (+ kamone) really nailed it with this well explained video. I really enjoyed how simple and effective this tutorial on arms. It goes into detail while also giving that detail a reason to be there. This helped learn a bit more about animating arms. I’m looking forward to your next video on the series.
Also, your character (OC I guess?) Gimberly is awesome. She’s cool.
This is probably a new TH-cam channel that I'm gonna have to watch avidly! Your tutorials made trying to understand the basics of 3-D animation intuitive and smooth. I hope you continue this for a while as I can see you getting very popular very quickly and there's gonna be many more like me wanting to see all of your videos.
The sheer amount of quality of the work put into this is insane and it does wonders for people like me who utterly dread having to sit down and watch a tutorial (it's also fantastic for actually keeping it in my memory,) in fact it actually makes it kind of fun as you add a lot of charm to it. Thanks a bunch!
This is so lovely and clear!!! Thank you for this 🙏
Not even an animator, but this is some high quality content coming from such an underrated channel.
Watched this two minutes before I needed to run to class thinking "it'll be fine I'll pause it in time". I in fact, did not pause it in time, and realized this video was way more engaging to me than I thought it would be especially since I found out it was about 3D animation which I don't do. Finishing this video now like way after class, Its pretty neat seeing how some of the things I'm seeing or hearing help with my idea of 2D animation as well. This is amazing, everything is so smooth, bouncy and so pleasing to watch and see, subscribed.
This is one of the best tutorials I've seen for anything. The presentation, information, length and charming character sets this video leagues above the rest.
THE FRAME.

As someone who uses a node-based 2D animation app, this tutorial was surprisingly helpful, especially with that reactions part! Also, I love the character you use to make these examples animated! It incorporates the cardinal directions’ colors in a 3D program, the gray and… darker gray missing textures, I love it a lot!
