Nice! Very “Kill Bill” :smiley:

Saw it on Twitter and i just had to ask, what do you use for velocity in the FLIP sim?
Is it just from an object normal or do you use another solution? i can never get a good “random” splashy feel to my splats. It always looks too controlled.

Great stuff!

Cheers,

The key is break up the emission shape and vel.

This is emission from a sphere with a mountain to make it undulate in all directions. Then add some noise to the velocity to break up the shapes, and use something like this to aim it in a direction - https://forums.odforce.net/topic/41847-source-flip-fluid-with-velocity/

Tons of surface tension and viscosity to help with “sheeting”

Also great tips in general here -
