Blur-Gaussian Layer


The Blur-Gaussian effect softens the image, reducing the amount of noise and detail. The look of the Gaussian blur is smooth, but does take some rendering time. This effect is useful when rendering time is less important, and quality is more important. Also, you can use a matte with this effect to isolate areas of the image.

Refer to the following example to connect this effect:


Parameter Description
Name Allows you to enter a name for the node.
Repeat Edge Pixels Makes the blur algorithm operate as if the pixel values beyond the edge of the layer are the same as the values of the edge pixels. This keeps edges sharp, preventing them from darkening and becoming more transparent.
Directional Blurs according to the length, width, and angle you specify. For example, if a character is walking east, the blur may fall to the west.
Blurriness Amount of blur applied to the layer.
Horizontal Blurriness Length of the blur.
Vertical Blurriness Thickness of the blur.
Angle The direction in which the blur is applied: sideways, up, down, 90 degrees, 45 degrees, and so on.
Bidirectional Blurs in both horizontal and vertical directions.
Invert Matte

Inverts the matte used to generate the effect. By default, the effect is applied to the opaque areas of the matte drawing. When this option is enabled, the effect is applied to the transparent areas of the matte instead.


Blurs the image the number of times the precision indicates at different radius (between 0 and the specified radius).
