What I mean is that I have a roll animation , but there is not one currently on the character , so I would not be swapping one roll animation for another , I would be adding it. Hence logic in the state machine and such, unless there is another way to swap a montage in without it. Note : the forum quote function does not seem to work for me , I click on it in a post , it turns orange but does not add anything when I reply , even if I select words first. Unless there is something else I am missing.
