These options appear as a subset of the section in the Paint Effects Brush Settings window, and the Attribute Editor for any brush node.
Turbulence causes irregularities (or noise) in the motion of tubes. Use these settings to define the turbulence force to apply to tubes. Turbulence can be applied as either a force or a displacement, depending on the Turbulence Type.
Defines which type of turbulence is created, and how it is applied to the tubes. You can select from the following types:
No turbulence is applied.
Turbulence is applied as a force in the local space of the tubes
Turbulence is applied as a force in world space. World Force is better than Local Force for groups of strokes that you want to share a continuous turbulence.
Turbulence is applied as a displacement in the local space of the tubes.
Turbulence is applied as a displacement in world space.
Turbulence is applied as a world space force. The force applied to the tips of the tubes is delayed from that applied at the roots, resulting in motion similar to grass blowing in the wind.
Turbulence is applied as a world space force. The force applied to the outermost branches is stronger than that applied to the parts closer to the root, resulting in motion similar to a tree blowing in the wind.
Defines the mathematical method used to smooth the values (and therefore the motion) in the turbulence calculations. Select from Linear, SmoothoverTime, or Smoothover Time and Space.
For a more realistic effect this should typically be set to Smooth over Time and Space. If the highest speed is more desirable than motion quality, select either Smooth over Time or Linear.
Defines the air speed due to turbulence. If the value is 0, no turbulence is applied.
Defines the amount of variance in the turbulence (either displacement or force) in space (or the size of the eddies).
Defines how quickly the turbulence changes over time.
Offsets the position of the turbulence by the defined x, y, and z values.
