Method

Downsample the resolution of the input image.

Attributes

Name	Description
Preview In Viewport	Preview the effect blended with alpha in the viewport.
Preview RGB In Viewport	Preview the RGB values in the viewport.
Preview Alpha In Viewport	Preview the alpha values in the viewport.
Iterations	how many levels of down sampling are generated.
Mode	Choose how the downsample output is filtered. Filtered, Checks the surrounding 3×3 pixels to downsample based on their average. Point Sampled, Only one point is sampled. Min Of Sampled, The minimum value of the points sampled is used. Max Of Sampled, The maximum value of the points is used. Bilinear Filtered, Linear blend is applied between pixels.

Inputs

Name	Description	Typical Node Input
Effect Mask	Mask out areas that Post-FX applied to this node won’t be applied.	Video Loader
Alpha Image	Add an image to control the alpha values of the image.	Video Loader
Active	Turn the effect on or off. Values < 0.1 will turn the effect off, and deferred rendering must be on.	Envelope Modifier

Outputs

Outputs an image or video that can be connected to any relevant video input, most commonly an Image 2D node.
