In iclone foot/hand contact works great. Great tools are also available in Unreal but you have to add to the blueprint. It would be SUPER helpful is as part of the iclone export, you could choose whether or not to include foot and hand contact on the avatar. If you choose "yes" then the imported CC avatar would have additional blueprints added for foot and hand contact. The work around is exporting the ground from Unreal into iclone. Livelink already taxes iclone/Unreal and drops the frame rate. Unreal terrains can be huge! Plus you have to make them line up perfectly at 0,0,0 in iclone as the 0,0,0 in Unreal which isn't that easy for larger environments. This would be a huge timesaver.
