What is Knee Pop

Hey Wayne,

Its your favorite Wayne again. I kind of did your course backwards but just finished it.  The course was fantastic,   I learned so much material I don't know if this old mind can absorb all of it.  I know I have a long way to go.  Because I would laugh to myself when you would beat up your animations because I am watching and thinking looks great to me,  But I do have question, you kept talking about knee pop and I guess my old eyes cam't see it.  So could you please give brief  description on what knee pop looks like.  Again Thanks  For The Course!

    Hi Wayne.

    Yes you are my favourite Wayne.  Even more favourite than this Wayne <I'm pointing to myself>

    Hey quick question before I answer your question, did you submit your work exercises?

    I beat them all up to make you even better.  Maybe you did and I've marked so many that I can't actually recall. So if you have, ignore me.

    But if you haven't..you really haven't finished the course yet;) 

    I think you will surprise yourself at the improvement you can make when you show your work to others.

    Now, what is a Knee Pop?

    This is an IK issue where the leg goes from straight to bent (or bent to straight) too fast and it causes a pop or jerky movement over 1 or more frames.  

    It's the kind of thing that once you see it, you won't be able to not see it.  And fixing them can be difficult because the cause could be many things or many things combined.  But with practice you can learn to see and learn to solve them.

    Hope that helps.

  • I second the idea that once you see it/identify it you can not help but notice it...

    and also the idea that it is one of the hardest things to track and fix
