Long name (short name) Type Default Flags
inputStart (is) nId NULL arrayoutputinputconnectablestorable
Input start eval connection from active nObjects. This should be connected from the eval start output of all the active nObjects simulated by this solver. Valid inputs are nCloth, dynamicConstraints, nBase, etc.
inputCurrent (ic) nId NULL arrayoutputinputconnectablestorable
Input current position eval from active nObjects. This should be connected from the eval current output of all the active nObjects simulated by this solver. Valid inputs are nCloth, dynamicConstraints, nBase, etc.
inputActive (niao) Generic n/a arrayoutputinputconnectablestorable
Input nData from active nThings. This should be connected from the output of all the active nThings simulated by this solver Valid inputs are nCloth (nBase, etc)
inputPassive (nipo) Generic n/a arrayoutputinputconnectablestorable
Input nData from passive nThings. This should be connected from the output of all the passive nThings connected to this solver Valid inputs are polygons, nurbs surfaces, nurbs curves, and lattices.
inputActiveStart (nias) Generic n/a arrayoutputinputconnectablestorable
Input nData from active nThings. This should be connected from the output of all the active nThings simulated by this solver Valid inputs are nCloth (nBase, etc)
inputPassiveStart (nips) Generic n/a arrayoutputinputconnectablestorable
Input nData from passive nThings. This should be connected from the output of all the passive nThings connected to this solver Valid inputs are polygons, nurbs surfaces, nurbs curves, and lattices.
outputObjects (noao) Generic n/a arrayoutputinputconnectable
Output Geometry for soft body.
currentTime (cti) time 0film outputinputconnectablekeyable
This is the current time used for the nucleus solve. By default, it is given an incoming connection from the main time node. This can be replaced with some other connection (e.g. from an expression or param curve), and then the solving is done based on that time value. There must be some incoming connection in order for the solve to take place and connected objects to play back.
startTime (sti) time 1.0film outputinputconnectablestorablehidden
The actual time of the start frame at the current frame rate.
startFrame (stf) double 1.0 outputinputconnectablestorablekeyable
The frame at which the solver will initialize and start solving. This attribute gets connected to all the objects controlled by this solver so that the start of the solve is synchronized.
frameJumpLimit (fjlt) integer 1 outputinputconnectablestorablekeyable
Maximum single step for solver. Solver will not try to compute a result when the current time jumps more than this value.
forceDynamics (fdn) bool false hidden
By requesting this attribute, all of the input active and passive and relationship things will be evaluated, and all output objects will be computed. It is intended to be used for batch mode and dynamics run-up.
