Tracer with spline dynamics ?

Hi everyone,

I was wondering if there is a way to affect a tracer with the spline dynamics tag, or some workaround to get a similar effect..
I have a bunch of particles emitting from a point, spreading around until they freeze in final position. The tracer is connecting all the particles with the center, much like a dandelion, but the lines are all straight and I would like them to flex and wobble under gravity instead, as they were ropes attached to the objects.

Any advice or hint would be much appreciated

Cheers
Massimiliano

You could use the tracer as the source for a mospline and then apply a random effector in noise mode to the mospline. But the ends wouldn't stick to particles so I'm not sure how you'd deal with that.

Massimiliano, you have to convert the Tracer to a spline object first in order to use dynmaics, since the tracer is a generator object.
be sure to set the spline type settings in oyur tracer to ypur desired needs beofre you connvert.
then in the spline dyn tag/properties set your anchors (usually first and last spline vertex).

hope this helps

Hi, sorry for the late reply and thanks for these advices !

@AdamT: yep tried that one already but as you say the ends won't stick to particles so is a no-go.

@fuat: I could do that but then it won't trace anymore Maybe I can bake the particles, get them traced and make an editable copy of the tracer to switch to...but it feels like overcomplicated. I was also thinking about creating a "polygonal instance" of the tracer with python but I'll have to study that..

Thanks
Massimiliano

Well, you could use falloff to prevent the noise from affecting the ends of the splines, but that might require a custom falloff object if there's variation in the distance.

yep, thats what i meant with "generator object". but i was a little unclear, sorry. my thought was: after converting the spline you could use an animated sweep on the dynamic spline. this would lok like a growing "traced" spline.
maybe give it a try.
hope thats clear...

Here's a technique I was messing around with. It's not particularly clean but maybe it could be adapted.

You could also emit a ton of particles to give the impression of a trail.
You could use this kind of approach and use a pConnector or Supertracer or something to connect up the trails. But limit the distance to something very small so each trail appears distinct.

Again not clean solutions but may just work.

thanks for the file, I'll try to look into it
