The image with Fast Noise’s Smoke preset applied.
The onscreen controls for position and rotation are visible.
Appearance
Controls for what noise pattern is generated. All parameters are keyframeable for changing the noise pattern over time.
— Preset: Select from some common noise pattern use cases: Mist, Smoke, Water Surface, River, and Heat Haze. Default is the standard noise pattern, and Custom is auto-selected if you change any of the parameters below.
— Scale: The size of the noise pattern.
— H/V Ratio: Controls the horizontal/vertical spread ratio.
— Detail Level: How many levels of fine detail to generate.
— Detail Balance: Applies weighting to the different scales of detail. The slider lets you choose between stronger large detail or stronger fine detail. A value of 0.000 removes fine detail entirely.
— Evolution: Changes the noise pattern gradually. This slider controls the “progress” of the noise pattern over time, rather than just modifying its current state.
Adjustment
Controls for adjusting the parameters of the noise pattern once it’s been generated. Especially useful for modifying the noise pattern’s Alpha channel for compositing. All parameters are keyframeable for changing the noise pattern over time.
— Brightness: Increases or decreases the gain of the noise pattern.
— Contrast: Moving this slider to the right makes the light areas lighter and dark areas darker in the noise pattern, increasing the contrast. Moving it to the left reduces the contrast.
