FK and IK Explained - Which One to Use and When?

[@freelance3dartist979]

You were a big help, I finally had the light bulb moment from your explanation! Thank you for taking the time to help everyone.

[@varudulc]

7 mins ago i had no effin clue what FK and IK meant, uve just made all my tears meaningless now thank yOU

[@loop5720]

noiceu!

[@J_A_C023]

🤣

i love that you make us realize the greatness of cat

[@mazenezou]

While Autodesk doing the opposite

[@Madlion]

your videos are amazing, I'm an Unreal developer but is now learning rigging and animation to understand the whole pipeline better and your videos are great for me who only knows 3dsmax

[@haticeleylaa]

I was taking classes about six months on Maya, but never understood what exactly IK/FK is. After watching your video, finally I got it. Thank you so much, it was so helpful and illustrative!

[@randomguy4738]

"i guess you're not here because of the math." YES I AM -_-

[@dishakhurana6739]

me too 😂😂😂😂i love maths too

[@gabrieldomingues6322]

one of the best tutorial focused youtube channels i ever found, well done, great and simple presentation and examples, you won a sub on patreon, totally deserved

[@krisluz5510]

Searched up for IK vs FK. This is by far the most concise video, insta subbed

[@KITATUS]

Fantastic video - Great style, simply taught and entertaining! Really nice stuff. Can't wait to see what you come up with in the future!

[@melissaobrien8139]

Omg THANK YOU. Finding anything related to this in 3ds Max is unusually hard but this was very helpful!

[@RenzoFlame]

This was very helpful, thank you. I was worried that there was a "correct answer" about using one or the other; or that once you start animating, you were just stuck with the one you started it with. It was good to see in action that you can easily change between them at will. Just a matter of find out how to do it with each program

[@cristianjuarez1086]

the correct answer is whichever one you need

[@DreamSyndromee]

I just got here from my animation class in uni and I understood better in these 7 minutes than in those other 40 lmao. Thanks a bunch!!

[@Dangermouse3435]

Never seen a better explanation. Thank you very much

[@rahuldeshpande9997]

IK is super awesome, Thanks for providing the above explanation and demonstration

[@To-mos]

A 2 bone IK solver most of the time uses the law of cosines to complete the triangle, however anything more than that has to utilize a jacobian matrix inverse to get closer and closer to the target position. The latter is what most robots use as a closed loop control system for feedback adjustments. The more you know :D

[@joshthebrawler]

Sorry to reply, but that's really cool! This helps me understand how the arms try to move so I can adjust and work accordingly, so thank you!

[@nijatIbrahimli]

Thank your amazing tutorial :)

[@candyrobot]

This was very helpful. Thank you!

[@diomiziofattorelli6609]

You are the best teacher in animation. Very talented and very clear explanations. Wish you the best!

[@mustafashamsi6426]

this animation taught me more than my Kinematics of Machines class

[@junimeme5626]

You can't get a better tutorial than this. Amazing

[@ninny65]

Fantastic video mate, understood everything with that accent of yours

[@jakubkotwica4034]

Milos I just love your narration :)

[@Jiry_XD]

Thanks a lot 😁, you deserve a lot more subscribers

[@Gregasaurus]

killer video yet again.

[@andreshernandezperez8762]

This video is the answer that i have been looking for, thank you

[@radenzito]

I can't believe this high quality content exist, it's hard to find nice CAT tutorials like this, well I they are unique, nothing comparable with that!!!! keep going, i'm going to support you on patreon, you deserve it

[@rahuldeshpande9997]

Some definitions: Effector: which is the part of the skeleton that interacts with the environment, such as a hand or a foot

[@Chechuuu2oo4]

Excellent all the tutorials, very useful, greetings.

[@theanimatedflame]

Really informative video! Thanks for this.

[@polygraphliedetector]

Thank you for sharing, this information was very useful when making decisions about animating.

[@AbbasKhan-dk5sb]

Amazing explaination !! You rock man 🤘🏻

[@matyasiszlay5532]

perfect explanation!

[@soundfxlab2837]

Thanks a lot, i agree with Paulo. If you create a full CAT Animation with all the principles that you know, you will create THE BIBLE OF CAT RIGGING in youtube, because there isn't many good tutorials or info about rigging, skinning and animating in Max.

[@sandeepadikkumbura]

Very well explained. Thanks for the tutorial

[@ajeet1994]

this video cleared my confusions and also taught me very useful things.

[@alaahesham250]

Very helpful and clear tutorial

[@AlexUdilov]

briliant tutorial man!!!

[@supersangwoo3342]

Very nice tutorial for 3DS MAX CAT !!!. Thank you~

[@ZeeshanAcademy]

Wonderfull explanation and great presentation video.. very usefull .. thanks

[@nounonarabara5702]

07 mnits = 7 months or years good tutorial and thank for the subtitles

[@MultiBRETTER]

still great explanation. I forgot about FK&IK within 3 years ;D

[@dremovremen1764]

Thanks for the clarification. Btw, what's the music is playing in the video?

[@prof_werneck]

Excellent demonstration! Thank you!

[@QuyenNguyen-xm3xr]

so good video tutorial, thanks so much

[@Seuthra]

Great explanation!

[@riky070483]

I'm Brazilian and I learned with you

[@jomoswagos]

thx, nice and short!

[@rkgamesstudio6977]

This helped me a lot

[@VlogrBlogr]

oh WOW. Thank you for this.

[@jakubszubka]

Great set of tutorials! Although I have to say, the music you chose to put in the background literally put me to sleep yesterday evening, soooo maybe next time go for something more energetic?

[@Samuraicbl]

Fantastic! You should do a full CAT animation tutorial from scratch!!!

[@ZackMathissa]

I eat cats

[@jabbarnendra563]

thank you for the explanation!

[@haryigit]

How can I stretch bones using CAT? I want my character's arms and torso to get longer when needed.

[@inkastoyanova7826]

very well explained

[@OnixSnipz]

In Maya, when you switch FK to IK, the controllers are at the same place, you don't have to click the Move IK Target

[@anonymoussloth6687]

What software do u use to do the animation at 1:50?

[@faktorial2]

Great video!

[@digital_ferret7263]

You created animation to make a video to teach future animators to make videos

[@montasserfaidi1966]

Good job 😍

hi Milos, is it a way to create a ik target for the head bone? i need to make a dinosaur bite something and his teeth atacched to the surface, for now i havent come with a good solution, i have tried of doing an ik target or a link constraint to the head but it doesnt work, i can only do link constraints for the leg plataforms so far

i found the solution, just using link constraint, the problem was that when aplied the bone would fly to some part of the scene, all i have to do is bring it back

[@LouiseChib]

is the feature to swithc from FK to IK, vice versa available in Maya and Motionbuilder?

[@citrusblast4372]

That was a realllly good video

[@nirwanaoryginal5956]

You try to give the video more brightness it will be great if you do

[@user-bi3xn8dj7y]

So could you do a mix of both ik for the shoulder and elbow and fk for the fingers...fully asking questions before a video finishes explaining things but this has all got me excited haha !

[@jayjaygolden5123]

how do i add an IK controller to a manual cat bone chain? (not a premade leg/arm/whatever)

[@maiax3i]

nice you saved my ass, pretty well done explained

[@MohamedNopy]

I can't say anything but thank you so much for these 7 minutes that have a comprehensive course.awesome

[@lifesymbiont5769]

What is the music used in the background?

[@johnleo1756]

One thing that was not clear to me, is the relationship between IK/FK and animation layers. I thought you could set one layer to FK only and another to IK only, but it seems not so...

[@buyinggf50gp10]

This information will come in handy when I play koikatsu.

[@MrJonh95]

nice video! subbed!

[@g-tech3113]

great video, thanks so much!

[@p-o2100]

Excellent! Thank you!

[@felipemaximo5021]

Gracias excelente video !

[@gerritschwalbe9079]

May i use some short parts from the video for a presentation in my university?

[@Ponlets]

can you teach how to do this in blender

[@i_am_a_real_cat1443]

Amazing channel!!!

[@chunld]

Thank you for those great tutorials,It's very useful! I have a question about Foot Ik platform, I hope it's flatten but IK/Fk switch will change it's pose especilly digit (toe).Thank you~

[@armeniouz3D]

Subscribed!

[@youchannel8454]

Good way to explain

[@MultiBRETTER]

nice! just created my first IK platform yesterday and I was wondering what FK/IK means. Got no matches in Max docs somehow. Very helpful tut! THX

[@gamedevmode]

Thank you so much!

[@manukureaboagye7405]

Lol! we are not here for the maths! Love your approach

[@FarmingWithAsifBashir]

Useful and informative. Thanks 👍😍😘💝❤️🔥😎

[@deepelements]

Great tutorials! Any chance you can make a tutorial on how to use cat in Unreal 4 or cryengine. CAT looks amazing but i'm worried about using it for my game animations because of the issues with rootmotion.

Thank You. I will get to that eventually. What issues are you referring to by the way?

[@jaxsykeses2059]

You making cool videos fam

[@SorbeX555]

Well explained, but the whole video feels like This War of Mine cutscene

[@tobiaswinter5495]

1:24 Yes, that's why I'm here, haha

[@armanchahal1]

thanks buddy

[@jasoncatlyn7331]

Thanks!

[@g-dev7336]

thank you ❤

[@unreal-forms]

and how to set limits for those bones stretching?

[@samchaos1588]

Ibrahim Bitam by using set driven key

[@theodorathanasiadis6629]

Excuse I want to say there are no muscles or articulations or path of motion with parameters

[@lukasw.7614]

1:27 lol I’m actually here for math

[@davav2688]

Amazing

[@kingmasterlord]

why can't each servo just know how far from zero it is? you don't even need inverse kinematics just tell it the numbers. shoulder 5, elbow 7, wrist 3: biceps flex pose.

[@unreal-forms]

is there an easy way to set the bones zero? if "freeze transformation" doesnt work! then what's the solution? it's the only thing i hate about CAT

[@crispincardoz8934]

thanks man

[@tuhinzahid7142]

Thanks a lot...

[@zubankesari7464]

Your accent sounds like Indian,Arabic and Mediterranean at the same time

[@srinandanasastry3001]
