| May 8, 2023 at 23:07 | comment | converted from answer | Confused_User | Moonboot's solution was correct, although I had to convert the curve to a mesh first and add a few subdivisions (while duplicating the original curve for the empty to follow). | |
| May 8, 2023 at 23:05 | comment | added | Confused_User | @moonboots I got it to work! I saw another thread about a similar problem where someone first converted it to a mesh. | |

| May 8, 2023 at 13:39 | comment | added | Gordon Brinkmann | Here are stills from your gif, on the left you can see how the proximity of the empty instead of simply making the tube wider in certain parts squeezes it down to make it spherical, on the right is what I would expect if I wanted to make the tube wider: squeezed tube. And this is just your example. If the curve would bend more and the OP maybe wanted even wider bulging, the tube would get much more deformed: deformed tube | |

| May 8, 2023 at 13:03 | comment | added | Gordon Brinkmann | The only problem with this solution is when it comes to narrower bends, for example in your animation where the tube ahead of the bulge is squeezed, because of how the modifier works. | |
