Paint Falloff

falloffs/paint-falloff·v1.5.1

IN:1 OUT:1

SUMMARY

Paint Falloff paints the falloff by hand: with Paint Mode on, holding Paint or its key adds weight under the brush in the operator viewer, Erase removes it and Erase All clears the painting, and the strokes persist from frame to frame. Brush Size stays constant on screen, and Transition Range, Align and Type soften the brush edge.

Depth Range limits the paint to points near the picked depth, Paint Through paints every point under the brush, and Show Group keeps points outside the Group from being painted. Like every POPX falloff, it adds optional Remap controls (clamp, fit, invert, ramp) and a Combine Operation with the falloff already on the points, and Preview Falloff colors the points by the result.

PARAMETERS

PAGEPaint

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.
Show Group	Showgroup	When on, points outside the Group are colored black in the painter and cannot be painted.
Paint Mode	Paintmode	Paint in the operator viewer. When off, the normal geometry viewer shows the output.
Home All	Home	Frames all points in the painter camera.
Auto Rotate	Autorotate	Orbit the painter camera around the geometry.
Paint	Paint	Hold to paint falloff onto the points.
[+]Paint Key	Paintkey	Sets the keyboard key that paints while held.
Erase	Erase	Hold to erase the painted falloff.
[+]Erase Key	Erasekey	Sets the keyboard key that erases while held.
Erase All	Eraseall	Clear all the painted falloff.
[+]Erase All Key	Eraseallkey	Sets the keyboard key that clears all the painted falloff.
Display Brush	Displaybrush	Draw the brush in the viewport.
Brush Size	Brushsize	Sets the brush radius as a fraction of the viewport height, constant on screen. 0.05 is 5 percent.
Depth Range	Depthrange	Sets how far in front of or behind the picked depth a point still gets paint.
Paint Through	Paintthrough	Ignore depth and paint every point under the brush circle, also over empty space.
Transition Range	Transitionrange	Soft edge of the brush, in Brush Size units.
Transition Align	Transitionalign	Shifts the transition in or out.
[+]Transition Type	Transitiontype	Determines a transition function for weights.

PAGEFalloff

[+]Combine Operation	Combineop	Specify how to combine this falloff with the existing falloff value.
Combine Falloff Attribute	Combattrscope	Sets the existing falloff attribute to combine with.
Swap Operation Order	Swaporder	Swaps the order of the operands. A operation B is changed to B operation A.
Combine Strength	Combstrength	Sets the blend of the combine operation, from 0 to 1.
Output Falloff Attribute	Outputfalloffattr	Name of the attribute the falloff is written to.
Preview Falloff	Previewfalloff	Enable coloring the points by the falloff.
[+]Falloff Ramp	Fallofframp	Selects the color ramp of the preview.
Open Custom Ramp Editor	Opencustomrampeditor	Open the editor of the custom preview ramp.
Reset Custom Ramp	Resetcustomramp	Resets the custom preview ramp.

PAGERemap

Enable Remap	Remap	Enable the remap controls.
Clamp	Clamp	Clamps the falloff values to the 0-1 range.
Fit	Fit	Enable fitting the values from the input range to the output range.
Auto Input Min Max	Auto	When on, the actual minimum and maximum values are used as the input range.
Input Min	Inputmin	Sets the minimum of the input range.
Input Max	Inputmax	Sets the maximum of the input range.
Output Min	Outputmin	Sets the minimum of the output range.
Output Max	Outputmax	Sets the maximum of the output range.
Invert	Invert	Invert the falloff, outputting 1 minus the value.
Enable Ramp Remap	Enablerampremap	Enable remapping the falloff through a ramp.
Open Ramp Editor	Openrampeditor	Opens the remap ramp editor.
Reset Ramp	Resetramp	Resets the remap ramp.
Custom Ramp TOP	Customramptop	Reference to a TOP used as the remap ramp, overriding 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.
