Combine Falloff

falloffs/combine-falloff·v1.3.0

IN:2 OUT:1

SUMMARY

The Combine Falloff merges multiple falloff attributes using mathematical operations to create layered and complex falloff effects. It supports various combination modes including addition, subtraction, multiplication, division, screen, overlay, and min/max operations.

Enables falloff composition by allowing you to stack and blend multiple falloff sources with independent gain controls. Each falloff input can be individually weighted and processed through a unified combination pipeline.

The result can be previewed with customizable color ramps (heatmap, blackbody, infrared, or custom) and output to a specified attribute for use downstream.

PARAMETERS

PAGECombine

Group	Group	If there are input groups, specifying a group name in this field will cause this POPX to act only upon the group specified.
[+]Combine Operation	Combineop	Mathematical operation used to combine falloff attributes.
Swap Operation Order	Swaporder	Reverses the order of operands in the combination operation (useful for non-commutative operations like subtraction and division).
Output Falloff Attribute	Outputfalloffattr	Name of the attribute where the combined falloff result will be stored.
Falloff	Falloffs	Sequence of falloff inputs to combine. Each entry specifies a POP source, falloff attribute, and gain multiplier.

In POP(s)	Falloffs0pop	Reference to the POP operator containing the falloff attribute to combine.
Falloff Attribute	Falloffs0falloffattr	Name of the falloff attribute to read from the specified POP.
Gain	Falloffs0gain	Multiplier applied to the falloff value before combining (0.0 to 1.0).

PAGEFalloff

Preview Falloff	Previewfalloff	When enabled, visualizes falloff values using a color ramp.
[+]Falloff Ramp	Fallofframp	Color ramp preset used for visualizing falloff values when Preview Falloff is enabled.
Open Custom Ramp Editor	Opencustumrampeditor	Opens the custom color ramp editor for defining a custom falloff visualization gradient.
Reset Custom Ramp	Resetcustomramp	Resets the custom color ramp to its default state.

PAGECommon

Bypass	Bypass	Pass through the first input to the output unchanged.
Free Extra GPU Memory	Freeextragpumem	Free memory that has accumulated when output memory has grown and shrunk.
Render Primitives	Renderprimitives	Toggles rendering of POPX Geometry or shows it as point instances only.
Convert to Point Primitives	Converttoptprim	Converts points to primitive points when Render Primitives is toggled off.
SRT / RST	Srtrst	Sets the transform order when using POPX Geometry as built-in TouchDesigner instances.
