Hi all

I'm trying to create the scene of an asteroid hitting earth, with a shot from space. As the asteroid hits earth, I want a ripple effect to come from the point of impact, like a tidal wave for example.

I am able to create a ripple on a flat ocean surface, but can't figure out how to add a ripple to anything else, like a sphere in this case.

Would anyone know how to do this? Any help would be appreciated.

Thanks
Rich
