 Wind-
specifies a vector, perpendicular to the distortion field, that bends the field to one side like wind.
The direction of the vector is controlled by positive and negative values, and the strength is con-
trolled by the amount of the value relative to 0.
For a realistic look, try keyframing gusts in this parameter.
Turbulence
Tu r b u l e n c e quickly and easily distorts images with turbulent noise.
Create water distortion, heat waves, and many other effects in your images. Create powerful organic dis-
tortions and exciting style effects, with maximum control:
Turbulence example
Note that because the controls are identical for horizontal and vertical distortion, we’ve only explained
them once.
Appearance
lets you choose between two different textures for the turbulent distortion field, giving you even more
variety and control over the distortion effect.
 Uniform -
returns a texture that looks more like distortions in water, heat waves, and reflections.
 Tur bule nt -
more closely resembles turbulent fluid, as you can see here:
