Hello I'm wondering how to stop pop fluids from moving after the sim has collided with an object.
I have tried grouping, drag, killing its velocity and force, stop on collision, enabled auto sleep.

Thanks in advanced! Attached is a simple scene that has pop fluids.

Tick the Add hit Attributes and response “stick”.

Or in an advanced way, for example you want the particle hit then dead by adding pop wrangle with something like these:
