3.12Tnpix_Stitch

Panel name Tnpix Stitch · also reachable as TnpixStitch

Holds cloth to cloth on the same Solver, or to its own folded parts. Stitches form when the simulation starts.

Property Type A Default Range Description

tnEnabled boolean true On/off.

stitchTo node array empty The garments to stitch to; each must be on this cloth's Solver. Append to it.

stitchToSelf boolean false Also stitch to this cloth's own folded-close parts.

searchDistance float (distance) 0.5 inch^† 0.0 – 100,000 How far a painted point looks for a surface, in scene units. A new modifier takes 0.5 inch in the scene's unit.

tightness float 1.0 0.0 – 1.0 1 = sewn onto the surface, 0 = keeps the starting gap (a rigid tack).

strength float 1.0 0.0 – 1.0 How rigid the hold is: about 0.5 holds, 0.8 and above is sewn shut.

channel string "" The painted channel that says where stitching is allowed.

threshold float 0.5 0.001 – 1.0 Paint at or above this value stitches.

showStitches boolean true Draw the stitches while the Stitch panel is open.

seamPasses float 1.0 1.0 – 10.0 Solver passes for the seam each step; whole numbers (fractions are rounded).

stitchToHandles integer array empty Storage: the targets by node handle, as the panel keeps them. Write stitchTo, not this.

offset float (distance) 0.0 0.0 – 100,000 A gap, in scene units, the seam keeps between the two cloths (this cloth keeps it).

activeTime boolean false true = the stitch holds only from activeFrom to activeTo.

activeFrom integer 0 -100,000 – 100,000 First frame the stitch holds; the pairs are found where the cloths are on this frame.

activeTo integer 100 -100,000 – 100,000 Last frame the stitch holds.

zoneOn boolean false Active Zone: a stitch pulls only while the zone reaches its seam, with its strength times the zone's value there. Works inside the Active time.

zoneHelpers node array empty The Influence Helpers that make the zone. Empty with zoneOn = no stitch pulls.

zoneStay boolean true Stays sewn once touched (the default): a stitch the zone has reached keeps pulling - a zipper. false = only the stitches inside the zone now.

zoneInvert boolean false Invert: a stitch pulls where the zone does NOT reach its seam (its strength times one minus the zone's value). With zoneStay, a stitch the helper has touched lets go for good. Empty zoneHelpers = every stitch pulls.

slide boolean false true = the stitched points stay on the surface they are sewn to, at the stitch's gap, but can slide along it.

friction float 0.3 0.0 – 1.0 How hard the sliding is: 0 slides freely, 1 does not slide. Used while slide is true.
