Inputs
The following inputs appear on the node tile in the Node Editor:
–
Image: The orange image input accepts an image containing a World Position Pass
or a Z-depth pass, depending on the desired operation.
–
Effect Mask: The blue input is for a mask shape created by polylines, basic primitive
shapes, paint strokes, or bitmaps from other tools. Connecting a mask to this input
limits the World Position Pass to certain areas.
–
Scene Input: The magenta scene input accepts a 3D scene input containing
a 3D Camera.
Basic Node Setup
Below, a MediaIn labeled RGBA contains the main rendered image from a 3D scene. A Z-depth
pass from a 3D-rendered scene is labeled Z_PASS. The Channel Booleans node is used to
map the Aux Z channel into either the red, green, or blue channel. The Z to World Position node
is placed after the Channel Booleans node, and an imported 3D camera that matches the
RGBA image is connected to the 3D camera input on the Z to World Position node. A Channel
Booleans node is placed after the Z to World Position node, which can remap the X, Y, and Z
positions for use in other nodes.
A Z to World Position node creates a World Position Pass from a Z-depth pass
Inspector
Controls Tab
The Controls tab determines whether you are creating a World Position Pass or a Z channel.
If there is more than one camera in the connected scene, this tab also selects the camera to
use for the calculation.
Mode
This menu switches between creating a Z channel from a World Position Pass or vice versa.
