Color Modifier

modifiers/color-modifier·v1.3.0

IN:1 OUT:1

SUMMARY

The Color Modifier modifies the color of each instance based on falloff values. It uses a color ramp (gradient) to map falloff attribute values to colors, enabling visually dynamic effects based on spatial relationships, proximity, or any custom falloff attribute.

You can customize the color palette using the Ramp parameter, which accepts either an internal ramp editor or an external Ramp TOP reference. This allows for flexible color mapping from smooth gradients to complex multi-color patterns.

PARAMETERS

PAGEColor

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.
Falloff Attribute	Falloffattr	Specifies which attribute to use for falloff values that drive the color ramp lookup.
Open Color Ramp Editor	Opencolorrampeditor	Opens the internal ramp editor for customizing the color gradient.
Reset Color Ramp	Resetcolorramp	Resets the internal ramp to default gradient values.
Custom Color TOP	Customcolortop	Reference to an external Ramp TOP for color palette.

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.
