Oversample

Diffuse node spread out bright pixel with some turbulence to create a smoke effect. This node is designed to work with the feedback system.

Properties

Dissipation

The amount of pixel faded away per frame.

Flow Properties

Flow effect add random turbulence to the image.

Scale

Scale of the turbulence effect.

Detail

Amount of iteration to apply turbulence.

Randomness

Frequency of seed change

Flow Rate

Flow intensity

External Forces

External Strength

Apply external force in/out of the middle point.

Rendering Properties

Threshold

Apply threshold after each step.
