[Closed] How to check if there is animation on an object?

it sounds like you already know what nodes need to be cleaned from animation. In this case it’s easier to replace transform controller with a new default instance of PRS controller:

-- let's do it for one selected node
animate off, redraw off, at time 0 
(
	tm = $.transform
	$.transform.controller = createinstance prs
	$.transform = tm
)

don’t specify the time if you want to clear the animation at the current time.
