Sorry to say but iClone 8 reverted all fixes back and added new issues.
Particularly with Path projected over to the custom made Terrain.
When we have "Follow Terrain" is set to OFF in Character Path properties and have Foot Contact ON, the character (specially in High Heels) walk is crippled (Foot Contact behavior is generally bad in iClone 8 compare to iClone 7). It is even worse if we enable "Follow Terrain" in Character Path properties. Same goes for Props on the Path over Terrain.
See video to compare nearly perfect iClone 7 behavior, to the crippled one in iClone 8: https://vimeo.com/928211252
