Hi,

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.

Thanks,

Eric

Try Newton - great for 2d real world physics.

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?

Not sure what you mean but yes you can animate the anchor position. Maybe Eric should post a link or a project file, this way we can all be on the same page. Just a thought.

I solved it by auto-tracing the object, then pasting the path it created into the anchor point motion path of my object. Phew, it worked!
