Animate Curl Noise Offset
April 24, 2017 3:25 a.m.
Hello, I'm new to Houdini
In the attached file I have a bunch of particles moving on the surface of an object and following a curl noise.
How would you go animating the noise offset over time? (so that particles don't remain following the same path)
Thanks in advance
PS. How do you deal with those rebel particles that escape so crazy fast?

Your setup looks like a partial from the
Sun tutorial on SideFX [
sidefx.com ].
In this tutorial, the curl noise is converted to velocity and the popgrain takes care of avoidance. Increase the Exterior band of the VDB to prevent velocity offshoot.
Here is my version of that tutorial but only with the particles on surface.
