Settings

Amount

Set the amount of noise to apply.
Range 0% to 400%, 100% is default and means noise spreads the full transparent to opaque range.
Amounts above 100% make the noise appear ever more pure transparent or opaque with less semi-transparent pixels.

Distribution
Set the type of noise distribution to use.
Uniform - Spreads the noise completely random.
Gaussian - Spreads the noise unevenly, often producing a more realistic effect.
