Hi Jonny, What you probably want to do is use states, so trigger state 1 if particle is inside the null. Then, on state 1 you could use a Linear interpolate using the particle age or age percentage. Safe? C On 17 July 2013 17:13, Jonny Grew wrote: > Hello! > > I'm trying to control a blend

If you clone the points clone the id into a new attribute, then you know which particle is the parent. And add a attribute that it's a clone. You can use that later to decide not to put orientation values on. Build a set from you tangent, whatever values and then you can select the corresponding
