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 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 causes the RGB values of the masked image to be multiplied by the mask
channel’s values. This causes 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 are 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 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 is 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 view. 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 are
displayed in the Inspector. Dragging a connected node from the node tree into the empty field
hides 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 reappears.
Comments
The Comments field is used to add notes to a tool. Click in the empty field and type the text.
When a note is added to a tool, a small red square appears in the lower-left corner of the node
when the full tile is displayed, or a small text bubble icon appears on the right when nodes are
collapsed. To see the note in the Node Editor, hold the mouse pointer over the node to display
the tooltip.
Scripts
Three Scripting fields are available on every tool in Fusion from the Settings tab. They each
contain edit boxes used to add scripts that process when the tool is rendering. For more details
on scripting nodes, please consult the Fusion scripting documentation.
