Attribute Falloff

falloffs/attribute-falloff·v1.3.0

IN:1 OUT:1

SUMMARY

The Attribute Falloff converts existing point attributes into falloff values. This allows you to use any numeric attribute (such as point index, custom data, or calculated values) as a falloff source, providing flexible control over how modifiers and effects are applied across your geometry.

Can optionally combine the attribute-based falloff with existing falloff values using various mathematical operations, and includes remapping controls to fine-tune the output range and distribution.

PARAMETERS

PAGEAttribute

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.
Input Attribute	Inputattr	Name of the point attribute to read and convert into falloff values. Default is _PointI (point index).

PAGEFalloff

[+]Combine Operation	Combop	Mathematical operation used to combine the attribute-based falloff with existing falloff values.
Combine Falloff Attribute	Combattrscope	Specifies which falloff attribute to combine with when Combine Operation is not set to Set.
Swap Operation Order	Swaporder	Reverses the order of operands in the combine operation (A op B becomes B op A).
Combine Strength	Combstrength	Blending factor for the combine operation, ranging from 0 (no effect) to 1 (full effect).
Output Falloff Attribute	Outputfalloffattr	Name of the attribute where the final falloff values will be stored.
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.

PAGERemap

Enable Remap	Remap	Enables remapping controls for adjusting falloff value range and distribution.
Clamp	Clamp	When enabled, constrains falloff values to the 0-1 range.
Fit	Fit	Enables remapping of falloff values from an input range to an output range.
Auto Input Min Max	Auto	Automatically determines input range from actual min/max falloff values.
Input Min	Inputmin	Minimum value of the input range for remapping.
Input Max	Inputmax	Maximum value of the input range for remapping.
Output Min	Outputmin	Minimum value of the output range for remapping.
Output Max	Outputmax	Maximum value of the output range for remapping.
Invert	Invert	Reverses the falloff values (1 - value).
Enable Ramp Remap	Enablerampremap	Applies a custom curve defined by a ramp to remap the falloff values.
Open Ramp Editor	Openrampeditor	Opens the ramp editor for defining the custom remapping curve.
Reset Ramp	Resetramp	Resets the remap ramp editor.
Custom Ramp TOP	Customramptop	Reference to an external TOP for remap control. When specified, overrides the internal 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	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.
