What is IK and FK?
Вставка
- Опубліковано 15 жов 2024
- IK and FK are both rig systems. In this video I demonstrate the difference and when to use each. I go over switching from IK to FK. This applies to all major 3D packages like Maya, Blender, Cinema 4D and others. Getting comfortable with the two systems will help you improve your animation.

Thank you sooooo much for this explanation!!
I'm a 2D frame by frame animator trying to get into rigging for cut out animation with Moho and it's been a nightmare trying to wrap my head around these terms!
I finally think I have a MUCH better understanding of these terms with this ONE video!
Thank you so much!
I plan to learn Blender animation as well and I will be back to see your animation videos when I do!
I'm happy to hear this video helped you!!
Good luck with gaining your new skills. I know you can do it!
Thanks for the note!

That Jump was Awesome dude...😂😂
haha thanks :)
Percise and humorsitic!
Thank you so much!!!!
Glad you enjoyed it! Thanks for your note!
Thank you for this
For sure, it was fun to do! Thanks for the msg!
awesome video, i understand that if the environment is influencing the character, Ik would be more beneficial, if the character is influencing the environment, FK would be more fluid
Thanks!
I think that's a good way to look at it. Know that you can change that up depending on the action and your preference.
Useful and direct! Thanks!
Thanks, glad it was helpful!
The greatest jump in history.
haha :D
Thank you buddy, was very clear and express! Hugs
Glad to hear that, thanks for your note!
I watched 30+ tutorials about ik & fk but i can’t understand Or i feel it’s to hard to understand but today i watched your tutorial End my all concept is clear about ik end fk
Thanks you so much ❤️
Please upload more animation tutorials i want to learn animation from you or if you have any paid
course please let me know
Thank you so muchhh ❤️❤️
Happy to hear the video helped and your understanding the concept. Thanks for your note!
I have no paid courses at this time. I'll keep uploading more videos :)
Thanks again!
Thank you so much, sir
you are the best ❤
waiting for the more exciting animation tutorials@@alexonstory
Thank you so much!
Happy to:)
Thanks for your note!
This guy's video is so good
Appreciate that, thanks!
NICE! great tutorial
Glad to hear that, thanks for your note!
Great explanation, but how do you actually set up the switch?
Thanks! The switch is an attribute on the armature or in the rig options.
I would search rigging tutorials IK/FK switch to get a more clear explanation on that.
Hi! Would you be able to make a tutorial on making a cg double?
I could animate a CG double, but not build one. That's not easy and requires a good modeler and surfacing artist. Or a 3D scanner. I would look in those place to help you find what your looking for.
That would be great! I have seen like 3D scan tutorials but not sure what would give me the best result at an indie level.@@alexonstory
@@Anand_Bhatt Cool adding realistic animation to my list.
I would look at Meta Human by Unreal. I have not played with it but it looks great. I think you can export into Blender. And even add motion clips.
www.unrealengine.com/en-US/metahuman
@@alexonstory so actually I already did make the Metahuman. The face is fine, not exact but it’s the body and clothing. Not sure how to make that match.
That's cool! I'm not sure either. But your on the hunt, good luck!
thanks mate!
My pleasure!
Very helpful video ^^
Can you please upload a full rigging and weight painting tutorial
Отличный урок! Спасибо.
Прыжок внутрь блендера выглядит жутковато, но смысл понятен)))
Thanks! Learning any software is tough at first. Stick with it and you'll slowly get it.
Thank you.
Happy to share!
Question about switching I haven't found an explanation to yet. If you switch from FK to IK at the point of contact with something, how do you avoid it screwing up the pose, since switching to IK makes the geometry jump back to the IK position.
Great question! Some new rigs do have IK/FK matching. But you don't need that.
I do switch over 1 frame. Then eyeball the position of the hand back to were it was before.
If you make the switch on action and over 1 frame no one is going to tell.
Hope that helps!
@@alexonstory oh I see. Thanks for replying! Great videos!
Did you 3D scan yourself or that was 2D just wanna know 😂
😁 I filmed myself on green screen then picked a frame to freeze frame. Cutout my shape and rigged myself in Blender.
best teatcher
Thank you!
Thank you so much 😭😩
Awesome I have to learn blender please refer any courses for complete process of animation start to end ( I don't know how to start and learn)
That's awesome!
I did create a video introducing Blender to beginners. ua-cam.com/video/R2RtKzrhubM/v-deo.html Walks you through the interface, hotkeys and basic tools. After that follow this beginner friendly course. ua-cam.com/video/dzX8DhN7zwQ/v-deo.html
Hope that helps you!
@@alexonstory thank you
For sure :)
Thank you
Happy to share :)
thanks sir i was finding video like this and ya i noticed you have very good jawline how you achieve it 😅
Thanks haha I think it's all that Vector cereal :)
Master ❤
Thanks Jearbear :)
Ur model is scanned yes? From different program
haha yes from life:) It's just me on a green screen.
@@alexonstory amazing bro but how u export as model?
I took a screen grab of me when I came to a rest and stopped the video.
I took that screen grab and created an alpha around me. Saved that and in Blender created a plane with my image texture. I added more definition to the plane and added some control bones to affect the different parts of my body. So essentially I made a paper cut out of myself.
@@alexonstory u good my friend
@@kaproductions777 Thanks!
Ik for legs and FK for everything else. So what about fixing fingers for retargeted animation?
Yeah pretty much Ik for legs Fk for feet, yup!
I don't work with mo-cap so I don't know. But I think mocap is retargeted to all FK bones, then a rig is placed on top of that, that can then have either IK or Fk.
@@alexonstory What about in general not mocap should fingers have ik or fk bones?
They can, but most times FK is all you need for fingers.
great
Thanks :)
Do more rigging tutorials
Will work on more for sure!
What would you use for a long tail?
FK is easier to set up for a long tail.
Animating in FK is also easier to build in offset/overlapping action. Depending on the action, however it is nice to have a tail in IK. As posing becomes much faster.
I would say if it's a pony tail or a cats tail I would animate it in FK. If it's a creatures attack tail that needs more performance I might go for IK with the Tail Rig system following the body COG.
Hope that helps!
thankyou
My pleasure :)
Blender 421, ik for me is why harder even for basic anim, ue4 tool mr mannequin and i want to create a basic draw both weapons from the back at the same time
How to switch between IK and FK automaticly?
Thank youuuuuuuuu
Sound , please ?
:)
dude you lool like a realistic 3D model. Like apple vision
haha thanks 😁
Hahashdsa I liked the video for the jump part hahahah
and subbed for quality content 👍😉
haha yeah that paper cut out jump is pretty funny! Thanks for your notes!!
Lol did not expect you to literally jump in. I liked the terrible animation too xD
:D haha nice, thanks!
i dont expect u really jump to blender😂
:D haha
wow that's what we call "clearly explained"
You look like the punisher from Netflix lol
haha you just gave me this years Halloween costume idea! :)

My teacher at college is so fucking bad that he didnt even explain what fk and ik mean. He just said there is fk and ik. And thats it. No explanation. I hate him.
That sucks! Unfortunately there are a lot of bad teachers in this space. Good for you for searching around.

Have you been in any fights in the last year?
haha why do you ask? I used to be a fighter?
thanks bro!!
Sound , please ?
Is the audio off? Too hot?
@@alexonstory no , I mean the name or type of music in the video and thank you
@@abdullahabdozied208 I'll have a look and see if I can find it :)
@@abdullahabdozied208 So I used Shazam to find it, love that app!
