softMod

Go to: Related nodes. Attributes.

The softMod node deforms one or more geometries by transforming them based on the falloffCurve attribute. The falloffRadius determines which points will be deformed by the softMod, and the falloffCenter determines the center of the falloffRadius sphere.

The accuracy of the deformation is controlled by the percentResolution attribute.

The envelope attribute can be used to globally attenuate the amount of deformation.

Long name (short name)	Type	Default	Flags
distanceCache (dic)	floatArray	nullptr
Internal attribute - value contains the cached set of distances when the useDistanceCache attribute is true.
distanceCacheDirty (dcd)	bool	true
Internal attribute - the dirty state of this attribute reflects the dirty state of the internal cache.
falloffAroundSelection (fas)	bool	true
If set to true then selected components will be deformed at centre weight
falloffCenter (fcr)	double3
Point around which to scale.
falloffCenterX (fcx) distance (double) 0.0cm X component of the point around which to scale.
falloffCenterY (fcy) distance (double) 0.0cm Y component of the point around which to scale.
falloffCenterZ (fcz) distance (double) 0.0cm Z component of the point around which to scale.
falloffCurve (fc)	compound	n/a
Define the falloff of the soft select by manipulating this ramp attribute
falloffCurve_Position (fcp) float 0.0 Position of ramp value on normalized 0-1 scale
falloffCurve_FloatValue (fcfv) float 0.0 Ramp value at the sibling position
falloffCurve_Interp (fci) enum 0 Ramp Interpolation controls the way the intermediate values are calculated. The values are: None: No interpolation is done; the different colors just show up as different bands in the final texture. Linear: The values are interpolated linearly in RGB color space. Smooth: The values are interpolated along a bell curve, so that each color on the ramp dominates the region around it, then blends quickly to the next color. Spline: The values are interpolated with a spline curve, taking neighboring indices into account for greater smoothness.
falloffInX (fix)	bool	true
If set to true then points will falloff in X
falloffInY (fiy)	bool	true
If set to true then points will falloff in X
falloffInZ (fiz)	bool	true
If set to true then points will falloff in X
falloffMasking (fm)	bool	true
If set to true then only selected components will be deformed
falloffMode (fom)	enum	0
How the falloff should be applied. A Volume based falloff (0) affects components based on their 3-dimensional distance from the influence point(s). A Surface based falloff (1) uses the distance across the surface being deformed.
falloffRadius (fr)	distance (double)	5.0cm
Point will only be deformed if they are within the falloff radius about the falloff center.
fastFalloffCenter (ffc)	bool	false
If set to true the deformer will use a faster, approximate method to seed the distance computation in surface mode. This could give a less accurate result if the geometry contains unusually shaped polygons.
geomMatrix (gm)	matrix	identity
Matrix to set account for the geom matrix at softMod creation time.
influenceMatrix (im)	matrix	identity
If a transform matrix is passed to this attribute then the softMod will update in that transform's local space.
angleInterpolation (ait)	enum	0
The direction of angle interpolation. In most cases 0 (Closest) will work the best. However, if components appear to be rotating in the wrong direction, a value of 1 (Positive) or 2 (Negative) may be needed.
limitCacheUpdates (lcu)	bool	false
If set to true the deformer will prevent cache updates when dependencies (input, fallOffCenter or other) will be modified Using this optimization will lead to unexpected behaviors in most cases
percentResolution (ptr)	float	5
resolution by which softMod percents can differ without being lumped together as a single percentage for efficiency
bindPreMatrix (pm)	matrix	identity
compensation matrix used when we rigidly deform the geometry
relative (rel)	bool	false
relative => only use weighted node i.e. no pre, post matrix
softModXforms (x)	compound	n/a
the bundled softMod transforms
preMatrix (pre) matrix identity worldSpace matrix above softMod weighted matrix
weightedMatrix (wt) matrix identity softMod weighted matrix
postMatrix (post) matrix identity worldSpace matrix below softMod weighted matrix
matrix (ma)	matrix	identity
transform that we will rigidly deform by when all percentages are at one
useDistanceCache (udc)	bool	true
If set to true the deformer will cache internal distances to improve performance at the cost of additional memory.
usePartialResolution (upr)	enum	0
whether or not to use the partial resolution
weightedCompensationMatrix (wcm)	matrix	identity
softMod weighted matrix compensation
