3.1Tnpix_Solver

Panel name Tnpix Solver · also reachable as TnpixSolver

The simulation. Its own on/off is 3ds Max's light bulb (there is no tnEnabled).

Property Type A Default Range Description

substeps integer A 4 1 – 99,999,985 The Substeps dial: the same number the Solver panel and the TenPix Graph show (4 = the default). Inside, the solver takes 15 more steps than this number each frame (4 runs 19).

iterations integer A 2 1 – 100,000 Constraint iterations per substep.

contactPasses integer A 1 1 – 16 Contact resolution passes per step. Raise it together with iterations and stretchQuality.

stretchQuality integer A 2 1 – 32 Extra passes for the stretch constraints (the edge net and the membrane) per substep. 2 is the normal solve.

smoothingIterations integer A 10 0 – 16 Surface smoothing passes per substep. 0 = off; 2 removes most of the zigzag of a dense mesh.

unlimitedGround boolean false Unlimited ground (Z = 0): an endless floor at Z = 0 for every garment of the Solver group and its threads, with no ground object and no collider.

strainLimit boolean true The Solver's own stretch limit, followed by fabrics that do not hold their own. No panel control; the fabric's limit is set on the material.

strainSweeps integer A 8 0 – 64 Sweeps of the Solver's own stretch limit. No panel control.

triangleStrain boolean true The Solver's triangle strain term. No panel control.

strainRateLimit float A 25.0 0.0 – 10,000 The Solver's own strain-rate limit in rest lengths per second, followed by fabrics that do not set their own. No panel control.

breathingAllowance float (distance) A 0.0 0.0 – 100.0 Contact give on the panel: a slide, in scene units, before contact friction grips. Not a stretch setting.

meshContactSoftness float A 0.0 0.0 – 1.0 Mesh contact softness: 0 = hard contact.

meshContactFast boolean false Not on the panel in this version. Leave at the default.

meshContactSmoothing float A 0.0 0.0 – 1.0 Mesh contact smoothing: blends contact across neighbouring points.

ccd boolean false Not on the panel in this version. Leave at the default.

redetectFastBody boolean false Not on the panel in this version. Leave at the default.

ccdMarch integer A 8 1 – 64 Not on the panel in this version. Leave at the default.

stressHeatmap boolean false Stress / contact heatmap display. Diagnostic only.

particleBonds boolean false Particle bonds debug display, drawn on every garment of the Solver group. Diagnostic only.

bondDistance boolean false Bond display: distance bonds.

bondBend boolean false Bond display: bend (hinge edge) bonds.

bondTriangleStrain boolean false Bond display: triangle strain.

bondWeld boolean false Bond display: welds (held only).

exactTriContact boolean false Not on the panel in this version. Leave at the default.

frictionInLoop boolean true Applies friction inside the solve rather than after it.

bodyStabilization boolean true Damps the jolt when a body starts moving under the cloth.

gammaDecoupleBody boolean true Keeps a body's push out of the fabric's damping.

bodyStrainComp float A 0.25 0.0 – 10.0 Lets the fabric give where it presses on a body. Mesh contact only.

collisionSystem integer 4 1 – 4 1 = Volume Only, 2 = Volume + Proxy, 3 = Surface + Volume, 4 = Surface (True Geometry). A value outside 1 to 4 is refused by the solver.

deepRescue boolean false Not on the panel in this version. Leave at the default.
