This is a nice technique for a problem I’ve being having, where I’d like to use Newtonian physics on closed loop where particles go round and round in the same direction. I solved this to a degree by using positive z on the curve force to get the particles moving round in the same direction, however doing this leaves a considerable amount of particles on the emitter?

I tried a closed loop, but I couldn’t replicate the issue. Perhaps by giving the particles an initial velocity? Here’s my file: http://pasteall.org/blend/index.php?id=46568

thanks Jonathan, that seems to have sorted it, it’s just the initial velocity on the x that make it work, without that, the particles go in both directions.
