This week I got the feedback on my walk cycle spline animation and had to make some changes to make the walk look better, like making the the heel bend a little more and avoiding knee pop.
Working on my spline animation I noticed a few problems like the feet were going inside the ground plane and there was some knee pop and my walker. I tried to fix everything in the graph editor and tried creating curves in the feet and body movement using the animation curve tool. After a short while I was able to fix most of the issues in my spline animation.
