Can you show us a screenshot of the result you're getting and a screenshot of your aux settings? I'm not quite picturing the problem.
Thanks for replying, i have attached a few Stills from the sequence bellow.
The Particles come in from the bottom left and swoop around to leave top left. They emit from the path and Turbulent position gives the distorted look.
In pic 2 when the particles fade out they fade from the path outwards which leaves a squiggle effect.
I am hoping to find a way for the particles to fade back in towards the path leaving the initial shape of the swoop.
or of a way to have the particles fade off in a smooth manner.
Thanks again for looking
If you animate the Turbulence position you can return the particles to the center of the path. Unfortunately this effects all of the particles at the same time. There is no control available to tie the amount of turbulence to the life of the particle. It's a global control.
BTW, a more effective screenshot would have been to select the particular layer and press the U key twice to reveal all modified properties of the effect. This makes it easier to recreate your settings. Another option would be to save and share an animation preset of the settings so we could easily see what you are doing with the effect.
Thanks for your help and advice, I am new to the forum so nit sure of the best way to present issues.
I have attached an image of the particular settings and also the saved preset.
I added the animation of the turbulence which does help make the effect a little smoother, but does as you said effect all the particles simultaneously.
The initial path is created by a null object with a light attached to emit particles from.
I think the lack of ability to keyframe the Aux particle controls is an issue for the effect I would like.
Thank you for helping me look into this issue Gerard. I will indeed contact RedGiant to see if they can add greater control on Aux Particles
