Fluid Gradients

Easily generate fluid gradients in After Effects with Potok. Gradients can be controlled and animated in many ways including other layers.

Potok is a fluid gradients plugin for After Effects. It generates noise and colorizes it with a gradient ramp. Gradients can be set from UI Gradient Control or from any Layer. Noise can be masked with any layer.

Potok Features

Noise

Potok plugin has a built-in noise generator with four noise types. Noise animation can be seamlessly looped. Also, noise can be multiplied with any layer to be masked or layer can be added to noise for precise control.

Gradient

The gradient ramp allows you to set any color control points and three interpolation modes. Gradients can be set from any layer which allows for unlimited animation and transparency possibilities. The gradient can be also be offset, scaled, and looped.

Color points interpolation: Linear, Sine, and Hard.

Colorize Mode

There are four Colorize Modes: Gradient, Gradient from Layer, Reflection from Layer and Refraction from Layer.

Gradient

Gradient from Layer

Refraction from Layer

Reflection from Layer

Lines

Draws isolines over generated noise as height with given steps, gradient with many randomizing and animation features.

Lines Alpha Noise

Make contours open by Noise Threshold. Noise can be randomized for each isoline.

Randomize

Randomize Lines Width, Offset, and Gradient.

Layers Maps

Gradient from Layer

Potok can map gradient over noise from any layer or composition. This allows for complex gradients driven by animation or alpha channel.

Masking Noise with Layer

Potok provides two layers to affect base noise. First layer multiples with noise in each pixel. Second layer adds to noise in each pixel.

Reflection from Layer

In this mode gradient maps over noise using normals in each pixel. It converts Base Noise brightness to Normal Map and then uses these normals as vectors pointing to sphere projects colors from Spherical Map.

Refraction from Layer

In this mode Potok displace pixels from a map using noise brightness as a distance to displace. Displaced maps can be looped.
