Grow source-aware chemical patterns such as spots, stripes, labyrinths, coral, and mitosis cells.

In: Organic

How it works

Grow spots, stripes, labyrinths, and cell-like patterns from the source. Pattern chooses the growth style; Growth advances it; Scale changes feature size. Use Seed From and Boundary to control where it starts and grows. Output can color the source, draw contours, displace it, or create a mask.

Location

Material / Organic / Reaction Diffusion

Controls

Select the layer to edit Reaction Diffusion in the Effect Panel. Open Parameters below for individual controls.

Actions

Double-click a control label to reset it. Use its function button to add keyframes or a driver.
