water balloons

[yujiyuji]

I'm trying to make a water balloon with vellum simlation that can be broken like the reference in this URL.
However, I can't create a cloth that shrinks all at once after it breaks, like the reference.
What parameters do I need to adjust to make the cloth shrink all at once after it bursts?
Can someone give me some advice?
Thank you very much for your help.

did you find any idea how to do this type of effect? I am having the same question here

I'm just guessing the method. It is Vellum + Flip fluid combine. For the water part, it is high-res, driven by a low-res FLIP simulation. In between of the process make the vellum balloon collide with low-res flip

1. Set up a low-resolution FLIP simulation inside an animated rigid ball, the manual animation shaping the draft visual.

2. Convert the rigid ball into a Vellum object to add higher detail and better visual interaction from dynamic collide with low-res flip.

3. Generate a high-resolution FLIP fluid, driven by the low-res flip water simulation, and make it collide with the high-resolution Vellum ball.

For Step 3 which can apply a potential method using a thin surface or a custom POP particle fluid. Since it is small-scale, computing per particle will not take much time while still producing decent visuals.

 For thin fluid surface, Houdini School has a good method, and it's quick
