Image Emitter
Updated: 4 Dec 2023
Emits ink into a field from an input image.
Image Emitter
Method #
This node emits colour/ink into a field based on an input image, useful for making 2D field effects based on a video feed.
The outputs from this node are just its transforms, useful for having multiple nodes follow the same motions without controlling each of their transforms individually.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details Position X
The objects position along the local x-axis.
Position Y
The objects position along the local y-axis.
Position Z
The objects position along the local z-axis.
Rotation Heading
The objects rotation around the local y-axis.
Rotation Pitch
The objects rotation around the local x-axis.
Rotation Bank
The objects rotation around the local z-axis.
Scale X
The objects scale along the local x-axis.
Scale Y
The objects scale along the local y-axis.
Scale Z
The objects scale along the local z-axis.
Control the inheritance of the transforms from the parent.
Parameter Details Position
Toggle inheritance of the Position from the parent.
Rotation
Toggle inheritance of the Rotation from the parent.
Scale
Toggle inheritance of the Scale from the parent.
World Position Only
Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time
Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details Image
The source image used to generate the field system. Can be overridden by an input image or video.
Thickness Mode
Which value to use effect the thickness scale of the field system.
Thickness
The thickness of the field system.
Alpha Threshold
The level at which you want the input alpha to start being applied to the field system.
Colour
The colour to emit.
Density
The amount of density to emit.
Velocity
The amount of velocity to emit.
Temperature
The amount of temperature to emit.
Hardness
Reduces the emission rate around the edges of the emission area to create softer looking edges.
Emission Mode
When to emit.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
