    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

    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!

    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

    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

    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

      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!

    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.

    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

    @johnleo1756 3 года назад

    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...

    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

    •  4 года назад +1

      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

    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.

    IK is more realistic than FK...That's why I like it! Would be useful in realistic games or animation so it won't look a bit faulty by the human eyes.
