Image Effects

Image effects change the appearance of the whole effect and are applied after all particles are rendered. You can specify which image effects are used and in which order they are applied by opening the image effects dialog from the main menu via View > Image Effects.... Note that image effects are only applied when rendering the effect to sprite sheets, image sequences and videos and not when used with runtime plugins for game engines.

The following effects are supported:

Option	Description
Contrast & Brightness	Changes contrast and brightness.
Hue & Saturation	Changes hue and saturation.
Gamma Correction	Applies gamma correction.
Color Curves	Modifies the colors by applying the user-defined color ramps.
Colorize	Colorizes the effect with the selected hue.
Palette & Dithering	Constrains colors to the specified palette. You can also specify how much dithering is applied.
Posterize	Reduces the number of possible colors in each color channel to the specified amount.
Grayscale	Converts the animation to grayscale. The Weights parameter controls how much each color channel contributes.
Invert	Inverts the colors.
Alpha Threshold	Discards parts of the effect that have an opacity below the specified threshold.
Pixelate	Applies pixelation to the effect. The parameter Pixel Size controls the amount of pixelation.
Horizontal Blur	Applies horizontal gaussian blur. Use Radius and Sigma to change how much blur is applied. In order to produce an evenly blurred image, combine horizontal and vertical blur.
Vertical Blur	Applies vertical gaussian blur. Use Radius and Sigma to change how much blur is applied. In order to produce an evenly blurred image, combine horizontal and vertical blur.
Motion Blur	Blurs particles with high velocity. The Radius, Sigma and Strength parameters control how much blur is applied.
Bilateral Filter	Applies bilateral filtering, which blurs the effect but preserves edges.
Kuwahara Filter	Applies the Kuwahara filter, which smooths out the effect.
Sharpen	Sharpens the animation. Use Radius and Sigma to change how much sharpening is applied.
Outline	Outlines the effect using the specified color and line width.
Film Grain	Applies a film grain effect.
