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 TBC
Emission Mode When to emit.
