Background: Originally I was making a water animation using displacement and needed a way to convert them to shape keys and fortunately Chipmasque provided a solution (exporting to .mdd). The problem now is that I need the animation to loop (and the water must appear to only be moving in 1 direction). Blender does not seem to be able to interpolate the vertex information well enough to maintain the illusion of movement (it will just change Z height back to the original position). I’ve tried changing the animation on the Null Object used to influence the vertex, haven’t found anything that looks good.
-Does anyone know a good way to loop this type of vertex animation?
