Color Modifier

modifiers/color-modifier·v1.5.1

IN:1 OUT:1

SUMMARY

The Color Modifier reads a float attribute on each instance, by default the falloff, and looks its 0 to 1 value up in a color ramp. The result is written to the point Color and carried onto the rendered pieces, so a falloff becomes visible in the viewport and in renders.

Choose a preset ramp (Heatmap, Blackbody or Infrared), a Custom ramp edited in the built-in ramp editor, or any TOP through Custom Color TOP. Position, rotation and scale are untouched, so it fits anywhere in a modifier chain, typically right after a falloff operator.

PARAMETERS

PAGEColor

Group	Group	If there are input groups, specifying a group name in this field will cause this POP to act only upon the group specified.
[+]Falloff Attribute	Falloffattr	Falloff attribute that drives the color ramp lookup.
[+]Color Ramp	Colorramp	Selects the color ramp preset. Custom uses the ramp editor or a TOP.
Open Color Ramp Editor	Opencolorrampeditor	Open the color ramp editor.
Reset Color Ramp	Resetcolorramp	Resets the color ramp.
Custom Color TOP	Customcolortop	Reference to a TOP used as the color ramp. It overrides the ramp editor.

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	Whether to render the full POPX geometry. When off, only point instances are drawn.
Convert to Point Primitives	Converttoptprim	Enable converting points to point primitives when Render Primitives is off.
SRT / RST	Srtrst	Sets the transform order, SRT or RST, used when the points are rendered as TouchDesigner instances.

ATTRIBUTES

IORead

popxFalloff

point float

Falloff attribute controlling where and how strongly the color is applied (default popxFalloff; set by Falloff Attribute).

IOModified

Color

point vec4

Instance color. The color ramp is sampled by the falloff and blended onto the existing color.

INPUTS

Input 0 POP - POPX/POP Geometry

OUTPUTS
