Here's the 2D and 3D skip that I animated following a JR tutorial. The reason the two don't run at exactly the same time is because I made a mistake with the original skip animation when compositing but this is really just to show the 3D animation next to what it started as.
First time using this rig too and it's great! Very easy to use. And can you believe it...I didn't even look at the graph editor once whilst working on this. Now that's old schoooool!
