Long name (short name)	Type	Default	Flags
inputStart (is)	nId	NULL
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
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
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
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
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
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
Output Geometry for soft body.
currentTime (cti)	time	0film
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
The actual time of the start frame at the current frame rate.
startFrame (stf)	double	1.0
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
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
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.
enable (ena)	bool	true
Toggle dynamics on/off for all the dynamic nThings using this solver
gravity (grty)	float	9.8
Defines the gravity affecting this nucleus
gravityDirection (grdi)	float3
Defines the gravity direction affecting this nBase system
gravityDirectionX (grdx) float 0.0 Defines the x component of the gravity direction.
gravityDirectionY (grdy) float -1.0 Defines the y component of the gravity direction.
gravityDirectionZ (grdz) float 0.0 Defines the z component of the gravity direction.
airDensity (ady)	float	1.0
Defines the air density affecting this dynamic system
windSpeed (wisp)	float	0.0
Defines the wind speed affecting this nBase system

This defines how much collisions can interpenetrate the thickness
usePlane (nupl)	bool	false
Defines whether or not we use a plane in the collision system
