Hi, all:
Boing Kit, my bouncy VFX plugin for Unity has just been released.
It can be used to create single-body & interactive multi-body bouncy effects. It utilizes the GPU to offload work from the CPU. It also makes use of Unity's job system (2018.1 or newer) for parallel computing.

Here's some more info:

Here's some technical explanation I wrote on the mathematical tool behind the effects, numeric springing:

Part 3 - http://allenchou.net/2015/04/game-math-more-on-numeric-springing/
My plan for next update is to add support for bouncy hierarchical/chained objects (e.g. bones) utilizing the same framework.
