I was trying to create a simple walking animation of a character in NLA. However, due to some unavoidable reason, I have to append walking animation on the same two characters once at a time. The positions of root bones of both the characters are at different locations. The same walking animation was also duplicated in Action Editor and linked in NLA with two characters. However, after doing all of the above some adverse movements on the second character is appeared, although, no problem in animation was found for the first character. A screenshot is attached. Please help.
