Hi,
i recently tried to start a new age attribute when the particles start moving.
I did it by adding @TimeInc to a new variable f@newage but i seems to happen only once and not per frame.
I would need the new age attribute to scale down pscale over time, but only after they star moving. Thanks for any hints
Hey Martin, there are probably some more official ways to build this, however my quick and dirty fix goes like this: Outside the flip solver, above the Flip_Src null create an attrib called age and set it to 0. Then inside the flip solver, add a new pop wrangle (just below the first one), set the group to @stopped==0 and inside the wrangle write @age+=1; – so after a point has left the stopped group, for each simulation step we increment the age attrib by 1.
