Make organic lines in particular BEHAVE.

[Steve Roberts]

Can you post a clip? I’m having trouble picturing what you’re getting.

And Christian has a point. Maybe you could draw the path, add 3D stroke (or just stroke) and animate the end point of the stroke, then move the stoke layer so it follows the action.

Ohmigosh, neither of you sees the obvious (not meaning to be rude here): The motion of the t_OrganicLines preset is created by:

a) the emission itself (Velocity)
b) the Turbulence field

Nothing really moves, so how can you expect it to follow a path if there is none? Basically all you need to do is

a) Load the preset.
b) Set Emission Velocity to Zero
c) Change Emitter Direction to Uniform
d) Change Emitter Shape to Sphere
e) Adjust Velocity from Motion
f) Adjust Lifespan and Emission Rate of the Aux System
g) Adjust the Turbulence field

Ok, thanks all of you for the replies.

Mylenium, I’m not sure how to adjust the turbulance field and velocity from motion in order to achieve one organic line which follows a path. I can’t seem to figure it out and I certainly cannot replicate what they did in that video I linked to.

Could you perhaps give me more details?

This effect is very simply, and does not need the Lines preset at all.

Simply create a particular layer….

1) set particle life to 4 sec (adjust to suit once done)
2) Choose glow sphere as part. type, 0 feather, size to 1, uniform direction
3) Size over life set to diagnol upper left to lower right linear line preset
4) Opacity over life set to quick lower left to upper mid to lower right pseude-pyramid preset
5) Set Physics time factor to 2.5 (adjust to suit once done)
6) ‘Velocity’ AND ‘Velocity Random’ AND ‘Velocity from motion’ set to 0

NO aux particles.
All other settings default.
ALL random settings to 0%

NOW simply animate emmiter (or track it) and nice flowing line will follow in beautiful fashion…..

btw – THere where 2 line effects in that spot,…….I am assuming you meant the second effect?? If I am wrong…uh, nevermind.

btw – If you are in a real bind,…..email me at jd@gfxmooo.com and I will send you the AE file I just whipped up,….it is for 6.5 Pro.

Nice one, Jeff!

[Jeff Dobrow]

he he….I beat my head against a wall on this one about 2 months ago……took awhile to get out of the Line preset mentality…..

[Steve Roberts]

Heh … no rudeness taken. Anything to get us out of this loop. 🙂

Thanks a lot Jeff, I started with the wrong idea in mind (Aux) and I got stuck there over and over again.
Nice work!

I didn’t really look at the example. This was a blind shot and I was under the impression he needed a specific feature of the organic lines preset. Apart from that, I rarely use the PTF unless need be, since it changes the entire evaluation of the particle system. I would have come up with a different solution, I think. But hey, use whatever gets the job done.
