Here are free scene files with 3 frames of USD caches for a water simulation for free to use for any purpose. Its setup with lights and shaders for Arnold renderer in GafferHQ. I will update the dropbox folder in future with other render engines setups like CyclesX , Karma, Omniverse or Unreal5.
I am using selfmade velocity blur node inside gaffer to get motionblur on changing point count
