Reply To: New Animation Course Coming?

I just did a little experiment with the standard Mixamo walk cycle. I started by making extrusions in the middle of the knees and colouring them yellow so they’re more visible. Then I rendered out the 24 frames from one contact pose with the right foot forward to the next that has the right foot forward.

I pulled these rendered frames into Photoshop and marked where the centre of the knee is for each frame and what I’m seeing is this:

From frame 5 to frame 8, when the body weight is on the right leg, the right knee almost comes to a complete standstill. It occurs to me that this is the critical part of the walk as far as knee pops go. Throughout the rest of the cycle, the knee is obviously moving forward, so that’s not the hard part of doing this. It’s just those four frames (5-8) where the progress of the knee has to be handled delicately.

Does this make sense?
