I have a run cycle for my character, but I realized after finishing it that I forgot to add the shadow to that animation. But when I add it to the animation by dragging it in, it disappears after second frame. I tried copying and pasting it over each frame but it starts flickering as if disappearing between frames. Is it not possible to add objects to the character after animating? I saw a tutorial on adding glasses to a character after the fact, but they attached to an exiting bone in the rig, which this wouldn't be able to do.
