Attributes

The bulletSoftBodyShape Node has 32 attributes.

Long name (short name) Type Default Flags

inWorldMesh (iwmesh)

mesh   hidden
input world-space mesh for the collision object as a mesh.

generateBendConstraints (gbc)

bool false  
Generate bend constraints when generating the inter-particle constraints for the soft body.

selfCollision (sc)

bool false  
Ability of soft body to collide with itself.

bendResistance (br)

float 0.01  
Controls how strongly the bend constraints will resist parts of the soft body bending.

linearStiffness (ls)

float 1.0  
Soft body stiffness to keep distance between particles.

friction (kdf)

float 0.01  
The friction between soft body and other objects.

damping (kdp)

float 0.0  
The overal damping factor applied to the motion of the soft body.

mass (mss)

float 1.0  
The total mass of the soft body.

pressure (pr)

float 0.0  
Determines how strong an enclosed soft body maintains its shape and volume. Setting a high pressure amount causes the body to expand, and low pressure will cause it to deplete.

drag (kdg)

float 0.0  
Controls the amount of drag as the soft body moves through the air.

lift (klf)

float 0.0  
Controls how strong the lift to be generated as the soft body moves through the air.

enableShapeMatching (shpmat)

bool false  
Soft body is to match shape during simulation.

shapeCoefficient (kmt)

float 0.0  
The strength of the shape matching constraints when using shape-based pose matching.

enableVolumeMatching (volmat)

bool false  
Soft body is to match volume during simulation.

volumeCoefficient (kvc)

float 0.0  
The amount of force used to maintain the shape's volume when using volume-based pose matching.

maxVolumeRatio (volmax)

float 1.0  
Max volume ratio for volume-based pose matching.

rigidContactHardness (kchr)

float 1.0  
Amount of penetration correction applied to contacts with rigid bodies.

kineticContactHardness (kkhr)

float 1.0  
Amount of penetration correction applied to contacts with static bodies.

softContactHardness (kshr)

float 1.0  
Amount of penetration correction applied to contacts with other soft bodies.

anchorContactHardness (kahr)

float 1.0  
Amount of correction is applied to follow anchor constraints.

collisionMargin (cm)

float 0.04  
Minimum allowable distance between the cloth and collision object .

positionIterations (pt)

int 10  
Positions solver iterations.

velocityCorrection (kvcf)

float 1.0  
obsolete

currentTime (ct)

time   hidden
Current time for the shape.

startTime (st)

time   hidden
Initializing time for the shape.

solverInitialized (solinit)

BulletSolverData::id   readable input
SolverData pointer to the initialized solver. Also makes sure data processed in the correct order for new/delete and add/remove.

solverUpdated (solup)

BulletSolverData::id   readable input
stub parameter noting that the solver has been updated for the current timestep.

outSoftBodyData (sbdata)

BulletSoftBodyData::id   readable output connectable
Soft body data (output).

outSolvedMesh (osolmsh)

mesh   output hidden
output mesh for the collision object as a mesh.

particleMass (partmass)

double array    
Mass scaling factor for each vertex.

particleBendResistance (partbr)

double array    
Bend resistance scaling factor for each vertex.

particleLinearStiffness (partls)

double array    
Linear stiffness scaling factor for each vertex.
