I'm using noises/turbulence in Pop Vops. The noise patterns these push the particles towards the positive X,Y,Z.

How can I get the noises patterns to work so the distribution is even?

You can set the Noise Type to ‘Original Perlin Noise’. This outputs noise with a range of -1 to 1, whereas Perlin Noise will output only positive numbers.

You can also use popforce dop if you want to avoid popvop.
You can also use VEXpressions there to contraol thing in your way.

Thanks very much guys.

I've used popforce, I just wanted to try out some different styles of turbulence.

Are certain types of noise just not suited to particles or is it a matter of getting a bit deeper into how they operate?

I tried subtracting .5 from the noise output and using a vex fit01 to adjust the ranges from 0 to 1 to -1 to 1 but with no joy.

In the houdini snapshot you posted you are wiring the turbulence in to the output v attribute. Try wiring the vector noise in to force as well to see the difference.

The POP Force DOP writes ultimately to the force output. Almost all pre-built POP DOPs write behaviour to force.

Writing to v or force will give you dramatically different results.

Inside the POP Solver DOP the force is mapped in to v to move the particles forward in an organic way.

Great, thanks all
