I want to create something similar to this ad at around 4 seconds in: https://www.themill.com/work/case-study/samsung-notebook-plus2/

enter image description here

You see these balloon-like objects that seem to be squeezed into a cube, like a mime. Then it's as though a boolean occurs.

I want to create something similar but with a sphere, and where the actual sphere is not visible, just the objects that are squeezed inside of it, like the ad.

I also want to replicate the boolean effect.

I've never tried soft body stuff or physics stuff before, and am unsure how to go about this.

  • $\begingroup$ Thank you! I tried this with a sphere and it seems to have worked only after adding collision to the sphere and flipping the normals, as well as adding collision to every bubble. However, when I try to do a boolean of a cube into the collision sphere (not the bubbles), they don't get squeezed, they pass right through the boolean as though there is no cube. Even if I add collision to the cube, it still doesn't work. $\endgroup$

    $\begingroup$ do you really have to use a boolean, can't you use an invisible object as a collision object? $\endgroup$

For the basic balloon trick, see the answer here. Then, instead of using Boolean, use an invisible object and give it Collision.

  • $\begingroup$ Well I do want to animate the balls as they move around, so I think I want to keep the simulation going to maintain that soft bouncing effect. Would this maintain that? $\endgroup$
