Back Hey ATR,
I did that, it's the rotation of the feet that's creating penetrations to the ground. Currently I'm manually fixing it, it'd be much faster to automate the process.
Kim,
Reposition in the Animation Mixer wouldn't work. Setting the offsets will just offset the animation but not the actual rotations of the feet penetration.
