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.
