Long name (short name)	Type	Default	Flags
airDensity (ady)	float	1.0
Defines the air density affecting this dynamic system
collisionFlag (cofl)	enum	4
Controls the type(s) of collisions that are processed.
collisionLayerRange (clra)	float	4.0
This defines how close the collisionLayer value for two objects needs to be in order for them to intercollide. For example if one object has a collisionLayer value of 2 and the other 5, then they will collide as long the collisionLayerRange is greater than 3.
collisionSoftness (clso)	float	0.0
This defines how much collisions can interpenetrate the thickness
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.
enable (ena)	bool	true
Toggle dynamics on/off for all the dynamic nThings using this solver
evalId (eid)	time	::maxTime
Used to prevent multiple evaluation in one frame Synchronized with aCurrentTime after any evaluation attempt This attribute is usually the same as aLastTime Unless the solver FAILED because the time step is too large Even the solver failed, this attribute will still be synchronize with aCurrentTime
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.
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.

Defines the gravity affecting this nucleus
gravityDirection (grdi)	float3
Defines the gravity direction affecting this nBase system

inputActive (niao)	Generic	n/a

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)
inputCurrent (ic)	nId	nullptr
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.
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.
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.
inputStart (is)	nId	nullptr
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.
lastTime (lti)	time	::maxTime
This is the time where the solver's current state is It equals to aCurrentTime - 1 before solve Or aCurrentTime after solve Must be synchronize with `fSolver.currentTime` before `fSolver.solve()` is called Note, this attribute will diverge from aCurrentTime if solver FAILED to update
maxCollisionIterations (mcit)	integer	4
Maximum number of collision iterations per subStep.
outputObjects (noao)	Generic	n/a
Output Geometry for soft body.
planeBounce (npbc)	float	0.0
Defines the plane bounce

planeNormalY (npny) float 1.0 Defines the y component of the plane normal.
planeNormalZ (npnz) float 0.0 Defines the z component of the plane normal.
planeOrigin (npor)	float3
Defines the origin of the plane in the collision system

planeStickiness (npst)	float	0.0
Defines the plane stickiness. If the total stickiness of the interacting things is 2 they will stick thoroughly
selfCollisionFlag (scfl)	enum	1
Controls the type(s) of self-collisions that are processed
skipSetup (sksp)	bool	false
Utility var to avoid recursive initialization Check the git history for more info
spaceScale (spsc)	float	1.0
Pretend that the the object is a scale model, and apply forces internally so that you get the expected behavior for the actual sized model
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.
startTime (sti)	time	1.0film
The actual time of the start frame at the current frame rate.
subSteps (sstp)	integer	3
Number of subSteps for each solve step.
timeScale (tisc)	float	1.0
Scale the timestep that the solver uses.
timingOutput (to)	enum	0
Controls the output of timing information
usePlane (nupl)	bool	false
Defines whether or not we use a plane in the collision system
useTransform (ustf)	bool	true
This applies the nucleus transform to the solver so that all simulation is done in a local space relative to the tranformation of the nucleus node. For example for a character on a train one could parent the nucleus node to the train and the solve for clothing will behave as if the train were stationary. (Note that one would generally also parent the nCloth and any constraints to the train as well) If this is off then nucleus always solves in worldspace and its transform is ignored.

Defines the wind direction affecting this nBase system
windDirectionX (widx) float 1.0 Defines the x component of the wind direction.
