This component adds turbulence that can be controlled. The turbulence generator is based on a fractal-like noise function, similar to the noise texture in Maya.

By default, the Turbulence component functions as a divergence-free force (or force with circular lines) that adds velocity.

However, you can also enable the Create Pressure mode, which will cause it to behave in a manner similar to the Phoenix Source in Volume Inject mode.

Note that by default, the Turbulence affects all Simulators in the scene.

You can also exclude the Turbulence from interacting with specific Simulators, by adding it to the Interaction Set in a Simulator's Scene Interaction rollout that is using the , with the set's Exclude List mode enabled.

Create Pressure  | injectMode – Switches between pressure and force mode. While force mode simply adds velocity, pressure mode works in a similar way to the Phoenix Source in Volume Inject mode, adding pressure to the areas displayed in red in the preview. This way the option will generally affect the appearance and behavior of the turbulent effect. Note that if Create Pressure is on, the Turbulence helper will not take into account the fluid density and will uniformly affect all voxels. However, if it's Not in Pressure mode, it will act more strongly on the dense voxels and more mildly on the ones where the channels in the Affect list have lower values.
