I followed the online tutorial for it's a pitch. I tried it with the skeleton as well as the knight and I have the same response (twice with both character's). When I set the frame 18 pose and use the slider to see the animation, both feet end up in the air between frame one and thirteen. It looks like the charter is hurdling. Its appears that it didn't regester the foot placement in frame ten. I can go back an replace the foot but I have to do it on a number of frames establish foot contaqct on the ground.
I am using v12q. I don't have the inverted knee problem others have discussed. I did set the balance and balance riged to 0 per the tutorial.
Any ideas??
