Create trails 1

- [Instructor] Alright so…now we've cached out our particles,…I'm gonna open up the parameters,…make sure load from disc is on,…go down to the group delete here and let's playback our sim.…And cool we've got this…really pretty languid particle system…that is emitting from the leading edges of our trails here,…our little bird.…So what we're gonna do is we're gonna start…making this into actual lines…and then refining those lines…to be the way we want them to be.…So first off we're gonna make an add…and this is gonna be the object…that turns these points into lines.…

Because we have our PNT attribute…that if we remember was created on the initial source points…and then basically got propagated…to every particle that emitted from those points.…So we can use every particle…that has that same variable value…and we can connect all those together.…So if I go to my geometry spreadsheet, let's highlight this,…you see under PNT if I sort by that…I have a number of points that all share zero…and then a number of points…that all share all these different numbers.…
