Paint Falloff v1.3.0

Summary

The Paint Falloff allows you to interactively paint falloff values directly onto POPX or POP Geometry in the viewport. When Paint Mode is enabled, use the assigned keyboard keys to paint, erase, or clear falloff values with a configurable brush. A Transition Range can be applied to create smooth edges between painted and unpainted regions.

Parameters

Page: Paint

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.
Show Group Showgroup – Highlights non-group instances in red to indicate areas that cannot be painted.
Paint Mode Paintmode – Enables interactive paint mode for direct falloff editing in the viewport.
Home All Home – Resets the viewport camera to frame all geometry.
Auto Rotate Autorotate – Automatically rotates the viewport camera around the geometry.
Paint Paint – Hold to paint falloff values onto instances.
Paint Key Paintkey – Keyboard key used to activate painting.
Erase Erase – Hold to erase painted falloff values from instances.
Erase Key Erasekey – Keyboard key used to activate erasing.
Erase All Eraseall – Clears all painted falloff values.
Erase All Key Eraseallkey – Keyboard key used to erase all painted values.
Display Brush Displaybrush – Displays the brush as a sphere in the viewport.
Brush Size Brushsize – Size of the paint and erase brush.
Transition Range Transitionrange – Width of the soft transition zone at the edge of painted regions.
Transition Align Transitionalign – Shifts the transition zone inward or outward relative to the paint boundary.
Transition Type Transitiontype – – Interpolation curve used for the transition zone falloff.

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.

Custom custom
Open Custom Ramp Opencustumramp – 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.

Page: Remap

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 Remap Ramp Enableremapramp – Applies a custom curve defined by a ramp to remap the falloff values.
Open Remap Ramp Openremapramp – Opens the ramp editor for defining the custom remapping curve.
Reset Remap Ramp Resetremapramp – Resets the remap ramp editor.
Remap TOP Remaptop – Reference to an external TOP for remap control. When specified, overrides the internal ramp editor.

Page: Common

Bypass Bypass – Pass through the first input to the output unchanged.
