Let's say I'm shooting 100 particles every frame. The particles are creating trails from the surface with Add SOP.

How can I make the end of the particle trail to follow its leader based on age or life to release its self from the surface?

Right now the end of the trail is connected to the surface. I tried to use carve and ForEach Sop but without the desired result. The carve node affects all of them simultaneously. I kind of like to create random carve where the trails disappear based on their age, a random movement.

Some interesting solution in this thread I was recommended to check out.
