I was trying to make a pipe with rounded cap or ends. Something like in the image. (where i just added to spheres as "ends".

enter image description here

I've already surfed the internet a little and it looks like an uncovered issue, as simple as it seems...

I need to do this bc i want to animate it later, like some type of growing body of water.

So, the method im trying out now is using a bezier curve and applying some bevel, beacuse of the "start bevel factor" and "end bevel factor" parameters wich can modify the length of the pipe from its start or its end. Very handy.

What i've tried later, was to select a sphere for the bevel object, so it would return a pipe with rounded caps...but it was impossible.

So i'm totally open to new approaches, if you have any ideas!

Thank you!

You can do this with an array modifier and a curve modifier (see this post):

  1. Add a slightly extruded circle/cylinder with no caps:

  2. Add an array modifier:

    enter image description here

  3. Add a curve modifier:

    enter image description here

    For the array to deform as expected the object origins must be in the same place.

  4. Add two half spheres as start and end caps:

    enter image description here

  5. the length can be animated with the Count value of the array modifier.
