Hi,
I have probably what's a total newbie question but in this particular case google isn't giving me what I need so maybe it's more unique than I think.  Please look at the attached picture.  The character is supposed to be clutching the arm rest but the character has some slight movement via mo cap data.  I need the hand to be solidly attached to that arm rest while the rest of the body is able to performer that slight movement.  How would I go about this?
Any help is greatly appreciated!!!   Thank you!
