Z Buffer Smoothing Node

When batch rendering 3D models originating from Maya, some unwanted artifacts may appear, particularly on models with outlines. This is due to problems with the depth information. You can use the Z-Buffer Smoothing node to smooth out the edges.

Connect the node following the example below.


Parameter Description

Enables or disables the selected node in the Camera, Timeline, and Node views.

Colour Swatch

Changes the node and layer colour.

NameUse this field to rename the node.
Histogram Range

Lets you define the range of clean pixels in the depth histogram when rendering 3D models. Only opaque or semi-transparent values are considered.

A low value means fewer pixels are used in the depth calculations and may flatten your object, while a higher value uses more pixels in the depth calculations, but may not eliminate all the image artifacts.

Kernel Size

Lets you determine the size of the matrix used for calculating the depth of a single pixel. For example, for an operation with a kernel size of 3 pixels, Harmony uses the pixels within a 1-pixel radius to calculate the effect. A larger kernel size means longer calculations.
