Are there some tutorials and tips around, covering characters interactions ? All the tuto's available have always only one character. What about interactions between two, three, or more characters. Interactions like hugging, pushing, fighting, playing, sport activities... etc. All kind of physical interrelationships.
 5 years ago, in a interesting thread, the answer was, clearly said, "nope" (with the notable exception of mocap). And in between ? Can someone point me in the right direction.
Thanks for reading
