Hello, excuse my noobness, but i am looking for a way to translate a bulge along a curve path to deform a tube. I have a tube and my curve, i add a metaball, to which i add a "follow path" constraint. The metaball moves along the path as i advance the timeline. then comes the time i select the tube , then bulge using the metaball as magnet. i now have control on the bulge, but now the bulge stays static and does not follow the metaball's path anymore. How can i achieve this? For my needs, it would be even better if i could just translate the bulge on one of the curve's axis, instead of having it animated over time. Thanks for any help ! Pierre D
