are you adding the turbulence on the position, like: "get
position->turbulence->set position"?
If so the turbulence will be very "strong" and mostly override the effect of
any forces.
if you add the turbulence as a force (turbulence->add forces), it's
influence will be less radical
for a flow along curve, I'd combine three forces / vectors.
- subtract pointposition of the closest location on the curve from the
particle's position (or the other way around) to pull the particles towards
the curve
- pointtangent of the closest location on the curve for the movement along
the curve
- turbulence to randomize
you can multiply each of those vectors with a scalar - and by changing the
scalars have fine control over the blending of the different forces.

Subject: particle flow along curve with turbulence
Hey list, I have some particles flowing along a curve nicely (with strands).
I would like to add turbulence to the particles, so they wiggle, but still
follow the curve(!) How do I do this without the particles going a-walk on
me? Whichever way I try it it, the turbulence always cumulate.
Feel like there's some memo on turbulence I didn't get.
Cheers!
