I use stuckon 3d's solution.
Sometimes, if nothing else works (and sometimes nothing does), I'llcut to another camera angle, to a close-up,or go to a shot of another character and then, when I come back to my main character I simply adjust their starting location to fit the animation.
It's usually just a few clicks left or right or forward or backward, not enough to be visible once the visual 'string' is broken. It can save alot of time and effort, especially if you're on a tight time schedule.
Just an idea from a rookie who can't always make Iclone conform tohis vision.
Indeed, that is a quick fix solution sometimes.
Just using different camera angles can sometimes fix that problem, as long as it does not mess with the consistency of your shot.
I have found that it is not too difficult to simply alter the transform states of the character when they decide to shift during an animation.
For example, in a recent shot I did, I have Imperial Stormtroopers and an Imperial Officer preparing to march off the set of a flight deck I'd built. The stormtroopers have to left face, and the officer has to right face. That was no problem. The problem came when I inserted a custom march animation for the troopers and the officer. When the animation starts, they would face a different (default?) direction. The quick fix for that was to place a new transform key at the start of the animation (just before they start to face off in the unwanted direction), then, as they complete their unwanted facing, I simply rotate the character in the direction I want him/her to go. This creates a new finalized keyframe for that purpose. It works pretty well, although on rare occasions I have to go in between the two keyframes to make adjustments if the character is looking like he/she still wants to turn back to the default direction during the transform phase. Again, it's all a quick fix, but it seems to work.
And Stuckon3D makes some awesome tuts in these problem areas!
I was once asked what I thought of human civilization.
I replied: "I think it's a wonderful idea!"
