User Manual

Process When Blend Is 0.0
The tool is processed even when the input value is zero. This can be useful if the node is
scripted to trigger a task, but the node’s value is set to 0.0.
Red/Green/Blue/Alpha Channel Selector
These four buttons are used to limit the effect of the tool to specified color channels. This filter
is often applied after the tool has been processed.
For example, if the Red button on a Blur tool is deselected, the blur will first be applied to the
image, and then the red channel from the original input will be copied back over the red
channel of the result.
There are some exceptions, such as tools for which deselecting these channels causes the tool
to skip processing that channel entirely. Tools that do this will generally possess a set of
identical RGBA buttons on the Controls tab in the tool. In this case, the buttons in the Settings
and the Controls tabs are identical.
Apply Mask Inverted
Enabling the Apply Mask Inverted option inverts the complete mask channel for the tool. The
mask channel is the combined result of all masks connected to or generated in a node.
Multiply by Mask
Selecting this option will cause the RGB values of the masked image to be multiplied by the
mask channel’s values. This will cause all pixels of the image not included in the mask (i.e., set
to 0) to become black/transparent.
Use Object/Use Material (Checkboxes)
Some 3D software can render to file formats that support additional channels. Notably, the EXR
file format supports Object ID and Material ID channels, which can be used as a mask for the
effect. These checkboxes determine whether the channels will be used, if present. The specific
Material ID or Object ID affected is chosen using the next set of controls.
Correct Edges
This checkbox appears only when the Use Object or Use Material checkboxes are selected. It
toggles the method used to deal with overlapping edges of objects in a multi-object image.
When enabled, the Coverage and Background Color channels are used to separate and
improve the effect around the edge of the object. If this option is disabled (or no Coverage or
Background Color channels are available), aliasing may occur on the edge of the mask.
For more information on the Coverage and Background Color channels, see Chapter 4,
“Understanding Image Channels and Node Processing” in the Fusion Studio Reference Manual
or Chapter 56 in the DaVinci Resolve Reference Manual.
Object ID/Material ID (Sliders)
Use these sliders to select which ID will be used to create a mask from the object or material
channels of an image. Use the Sample button in the same way as the Color Picker: to grab IDs
from the image displayed in the viewer. The image or sequence must have been rendered from
a 3D software package with those channels included.
Hide Incoming Connections
Enabling this checkbox can hide connection lines from incoming nodes, making a node tree
appear cleaner and easier to read. When enabled, empty fields for each input on a node will be
displayed in the Inspector. Dragging a connected node from the node tree into the field will
hide that incoming connection line as long as the node is not selected in the node tree. When
the node is selected in the node tree, the line will reappear.
