first time posting a question here, so if its in the wrong format etc. then please let me know! Building an animation for a client and they're looking for this kind of effect on a curve shape.
I've tried geometry nodes and weight painting which almost worked but unfortunately seems to take away from the volume rather than displace it (the client was clear that the volume has to be consistent). attempted using the displacement and wave modifiers but there were issues with both of those approaches as well, if anyone has any advice then I would greatly appreciate it.
