I'm trying to animate an irregular shape, ie an egg, so it looks like its rolling along the ground. Is there a way that I can pin the path of the egg shape to a particular spot while I rotate it ? I've already tried motion paths and auto-orient, but with no luck, the motion still looks unnatural.
Not sure what, exactly, you are trying to do but the Anchor position is important for this kind of animation. If an egg, you would probably want the anchor in the center and closer to bottom of the egg. Use the Pan behind tool and change the position of your anchor.
I gotta disagree with that. The anchor point needs to animate-- otherwise, the egg will either overlap the surface, or won't touch the surface, since the shape is uneven. I'm curious about how to solve this too-- perhaps animating the anchor point? That is possible, right?
