Hi

Sorry for this really basic particles question but I'm trying to render a still of quite a few contrails criss crossing each other (using Maya 7.0)

I'd like something like this

At the moment I have this

Ideally as the particles get further away from the jet I'd like to increasingly churn their position up, spread them out, add randomness to their positions.

Currently my particles increase in size the further they travel (radiusPP connected to a ramp + particle cloud shader with a cloud texture mapped onto the blob map).

So any suggestions how I increase the noise at the far end of the contrail?

thanks in advance

try connecting a turbulence feild to the particle shape.

thanks Akewt

adding a turbulance and ONLY ramping up the frequency seems to have done the job.
