<div dir="ltr"><div><div><div>Hi<br><br></div>I am using a calculator filter to get the
y co-ordinates for a series of particles. I am then using that data to
color by y position. However this color is changing over time as the
particles move. I would like to "lock in" the first value, ie the
original y position of the particles. Is this possible?<br><br></div>Is
there a function in the calculator or maybe a filter I can add to make
sure the calculator data table isn't updated at every time increment?<br><br></div>cheers,<br>Tim</div>
