Color Modifier
v1.3.0Modifiers
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
Group
GroupIf there are input groups, specifying a group name in this field will cause this POPX to act only upon the group specified.
Falloff Attribute
FalloffattrSpecifies which attribute to use for falloff values that drive the color ramp lookup.
Open Color Ramp Editor
OpencolorrampeditorOpens the internal ramp editor for customizing the color gradient.
Reset Color Ramp
ResetcolorrampResets the internal ramp to default gradient values.
Custom Color TOP
CustomcolortopReference to an external Ramp TOP for color palette.
Bypass
BypassPass through the first input to the output unchanged.
Free Extra GPU Memory
FreeextragpumemFree memory that has accumulated when output memory has grown and shrunk.
Render Primitives
RenderprimitivesToggles rendering of POPX Geometry or shows it as point instances only.
Convert to Point Primitives
ConverttoptprimConverts points to primitive points when Render Primitives is toggled off.
SRT / RST
SrtrstSets the transform order when using POPX Geometry as built-in TouchDesigner instances.
