These renders were made following the 'Houdini: Particles' tutorial by Scott Pagano, which I learnt a lot from relating to particle effects and the node tree.
I followed an Applied Houdini tutorial for establishing smoke simulations in Houdini and this was the result. I replaced the source object with a cube and changed some minor settings, but otherwise followed the tutorial example.
A single fully rendered frame; I had an after throught that if the water is transparent then next time I need to add bubbles and followthrough trail of effects.
Rough splash animation from sheets, strings, beads to dissipation.
