i made a scene where particles leave nurbs cylinder trails.

i create particle trails from moving particles. then i use those trails in a forEach SOP. i separate the forEach iterations with the trailParticles parent attribute to get one whole trail. them i just copy circles on those and skin it.
it works ok but the main problem is the speed.

could there be a better way to use the forEach SOP or maybe a completely different approach?
cos right now forEach SOP has to go through all the trailParticles in each iteration to check if their parent attr matches with the current iteration number and it gets easily very slow.

here is the polywire technique
the wires are polygonal, but if you need smooth surfaces i suggest you to render them as subds instead of converting them to nurbs

simple and efficient,
thank you Tomas!
