Equalize

In: Adjustments

Description

The Equalize filter adjusts local contrast based on a distance range. The goal of the Equalize filter is to reduce large differences in each channel. As a result, it's generally useful as part of the Image to Material (B2M) workflow - the Image to Material (AI powered) filter includes an Equalize pass within the filter to improve results.

The images below show the Equalize filter in action.

Before the Equalize filter has been added, there is significant variation across the height map and base color of this material.

After the Equalize filter has been added, both the height map and base color channels are more uniform without losing detail.

Parameters

Basic parameters

  • Input Tiled: toggle
    When enabled, treat the material as if it's tiled repeatedly, so changed near borders will be influenced by color values on the opposite border.
  • Radius: 0-1
    Spread the Equalize effect over a wider area.
  • Keep Local Differences: toggle
    Enable to make the equalize effect work at a higher resolution to maintain details.
  • Override Per Channels: toggle
    Enable to control the filter for each channel independently. Sections will appear for each channel when this toggle is enabled.

Mask

  • Custom Mask: toggle
    Enable or disable the use of a custom mask for this filter
  • Custom Mask Invert: toggle
  • Custom Mask Blur: 0-1
    Blur the custom mask. This is useful for smoothing the edges of the mask.
  • Custom Mask: image/brush
    Select an image to use as a mask, or use the brush to paint a custom mask directly in the 2D view

Channel

The controls for each channel work the same way.

  • Override Common Parameters: toggle
    Enable this to customize the Equalize effect for this channel. When enabled, additional controls appear:
    • Input Tiled: toggle
      When enabled, treat the material as if it's tiled repeatedly, so changed near borders will be influenced by color values on the opposite border.
    • Radius: 0-1
      Spread the equalize effect over a wider area.
    • Keep Local Differences: toggle
      Enable to make the equalize effect work at a higher resolution to maintain details
  • Target Mode:
    Select how to bias the Equalize effect. By default Equalize attempts to move colors towards the average color of the channel. Use Parameter to instead bias towards a chosen color or value. With Parameter selected, an additional control will appear:
    • Target: color select
      Select a color or value to act as a target for the Equalize algorithm.
  • Custom Color Variation: HSL sliders
    Adjust the Hue, Chroma (Saturation), and Luma (Luminance) of the result after the Equalize algorithm has been run for the specified channel.
