Thank you very much for interest in this lego effect shot.
Breakdown was added.
I'd like to be of help, even if it's only in a small way.

BGM : "Ievan polkka" by HATSUNE MIKU.
-----------------------------------------------------------
Done in Houdini, render with Mantra PBR. Comp in Nuke.

Solution is simple.
I converted pyro and water sim to polygon And I put uniform Gap points in polygon.
Especially vdbvisualizetree node was very useful.

And house, car, concert venue and ad-balloon's body are sketchup or LDD file format.
these were used in houdini through 2 or 3 times converting format.

Thanks for watching.
