I've seen a lot of motion graphics animations from Cinema4D - expanding balloons compressed into a shape. The most recent one is the animation from Mi Fans 2021

enter image description here

Here's what I've tried:

  1. First thing I tried is using a Cloth simulation instead of Softbody, thinking it will expand by using the pressure settings.

  2. I tried Softbody, but because the object cant expand on its own, I added a Force Field inside, and here's what happened.

enter image description here

It works for some, but as you can see, as the "balloon" expands it leaves the force field so now the force field is pushing the object to a corner.

Right now I'm still finding the best way to do it in Blender, I've researched some c4D tutorials to get the idea of how to do it.

Cloth Simulation > Presure seems to be working in some way ... just a quick test. You already noticed presure is not expand sphere shapes and Cloth object Scale transformation is not taken into account during simulation. So what I did here instead of expanding bubbles I scaled down collision object (Cube).

@RichSedman answer should work ... seems to be more stable and is using "expanding" ballons ... that is what you asked for.

  • $\begingroup$ That looks pretty good. I've been refining my original solution and think I've improved it somewhat... it might take me a while to write it up as an answer though. I'll add it when I can. $\endgroup$ May 4 at 22:10
  • $\begingroup$ instagram.com/p/CNctrJfHwQ5/?utm_source=ig_web_copy_link in the link I attached, the baloon is the one that expands, not the cube that shrinks, but i guess i'll try to play more with the cloth simulation $\endgroup$ May 6 at 5:37

    $\begingroup$ I know .. and for that I mentioned that ... and that is why I mentioned also Rich's answer that does what you asked expanding SoftBody bubbles. So use that one :) $\endgroup$
