I am using finalIk to rig my avatar in my project. Looks okay. I also have a few animations downloaded from mixamo that I am using with it. However, there is a particular animation (clapping) that when used on my avatar, the two hands do not meet with each other. for some avatars, the hands go into each other, the clapping are not proper like it is shown in mixamo.
Edit: I have noticed that I can solve this with the Character Arm-Space variable (see attached image) in mixamo's animation options. How can I control this variable at run time.
