polySplitRing(*args, **kwargs)¶

Splits a series of ring edges of connected quads and inserts connecting edges between them.

Flags:

Long Name / Short Name		Argument Types	Properties
adjustEdgeFlow / aef		float
	The weight value of the edge vertices to be positioned. Default:1.0f
caching / cch		bool
	Toggle caching for all attributes so that no recomputation is needed
constructionHistory / ch		bool
	Turn the construction history on or off (where applicable). If construction history is on then the corresponding node will be inserted into the history chain for the mesh. If construction history is off then the operation will be performed directly on the object. Note:If the object already has construction history then this flag is ignored and the node will always be inserted into the history chain.
direction / dr		bool
	This attribute is used when doing an absolute split. If true then the distance is taken from the start vertex of the root edge. If false the distance is taken from the end vertext of the root edge. Default:true
divisions / div		int
	Number of divisions. Default:2
enableProfileCurve / epc		bool
	Enables the use of the profile curve. Default:true
fixQuads / fq		bool
	Fixes splits which go across a quad face leaving a 5 and 3 sided faces by splitting from the middle of the new edge to the vertex accross from the edge on the 5 sided face. Default:false
frozen / fzn		bool
insertWithEdgeFlow / ief		bool
	True to enable edge flow. Otherwise, the edge flow is disabled. Default:false
name / n		unicode
	Give a name to the resulting node.
nodeState / nds		int
	Maya dependency nodes have 6 possible states. The Normal (0), HasNoEffect (1), and Blocking (2)states can be used to alter how the graph is evaluated. The Waiting-Normal (3), Waiting-HasNoEffect (4), Waiting-Blocking (5)are for internal use only. They temporarily shut off parts of the graph during interaction (e.g., manipulation). The understanding is that once the operation is done, the state will be reset appropriately, e.g. Waiting-Blockingwill reset back to Blocking. The Normaland Blockingcases apply to all nodes, while HasNoEffectis node specific; many nodes do not support this option. Plug-ins store state in the MPxNode::stateattribute. Anyone can set it or check this attribute. Additional details about each of these 3 states follow. StateDescriptionNormalThe normal node state. This is the default.HasNoEffectThe HasNoEffectoption (a.k.a. pass-through), is used in cases where there is an operation on an input producing an output of the same data type. Nearly all deformers support this state, as do a few other nodes. As stated earlier, it is not supported by all nodes. Its typical to implement support for the HasNoEffectstate in the nodes compute method and to perform appropriate operations. Plug-ins can also support HasNoEffect. The usual implementation of this state is to copy the input directly to the matching output without applying the algorithm in the node. For deformers, applying this state leaves the input geometry undeformed on the output. BlockingThis is implemented in the depend node base class and applies to all nodes. Blockingis applied during the evaluation phase to connections. An evaluation request to a blocked connection will return as failures, causing the destination plug to retain its current value. Dirty propagation is indirectly affected by this state since blocked connections are never cleaned. When a node is set to Blockingthe behavior is supposed to be the same as if all outgoing connections were broken. As long as nobody requests evaluation of the blocked node directly it wont evaluate after that. Note that a blocked node will still respond to getAttrrequests but a getAttron a downstream node will not reevaluate the blocked node. Setting the root transform of a hierarchy to Blockingwont automatically influence child transforms in the hierarchy. To do this, youd need to explicitly set all child nodes to the Blockingstate. For example, to set all child transforms to Blocking, you could use the following script. import maya.cmds as cmds def blockTree(root): nodesToBlock = [] for node in {child:1 for child in cmds.listRelatives( root, path=True, allDescendents=True )}.keys(): nodesToBlock += cmds.listConnections(node, source=True, destination=True ) for node in {source:1 for source in nodesToBlock}.keys(): cmds.setAttr( ‘%s.nodeState’ % node, 2 ) Applying this script would continue to draw objects but things would not be animated. Default:kdnNormal
profileCurveInputOffset / pio		float
	Changes the offset to the multisplit profile curve. eg. if the profile curve values go between 0 and 1 and this value is set to -1 then the profile curves values will be adjusted to go between -1 and 0. Default:0.0f
profileCurveInputScale / pis		float
	Changes the range of values that the profile curve represents. eg. if the profile curve values go between 0 and 1 and this value is set to 2 then the profile curves values will be adjusted to go between 0 and 2. Default:1.0f
profileCurve_FloatValue / pfv		float
profileCurve_Interp / pi		int
	????? Default:0
profileCurve_Position / pp		float
rootEdge / re		int
	The weight attribute uses the start vertex of this edge to determine where the new split occurs. Default:-1
smoothingAngle / sma		float
	Angle below which new edges will be smoothed Default:kPi
splitType / stp		int
	Format: 0 - Absolute, 1 - Relative, 2 - Multi Default:TdnpolySplitRing::Relative
useEqualMultiplier / uem		bool
	Changes how the profile curve effects the offset when doing a multisplit. If true then the verts will be offset the same distance based on the shortest edge being split. If false then each inserted edge loop will be offset a distance relative to the length of the edge that is being split. Default:true
useFaceNormalsAtEnds / fne		bool
	When doing a multisplit on a set of non-closed edge ring this will toggle the normals at the ends of the split to be calculated as the edge normal or the face normal. Default:true
weight / wt		float
	Weight value controlling the relative positioning of the new points on existing edges. Range is [0.0, 1.0]. Value of 0.1 indicates the new edges will be placed closer to the start vertex of the first edge of the sequence of edges. Default:0.5
worldSpace / ws		bool
	This flag specifies which reference to use. If on: all geometrical values are taken in world reference. If off: all geometrical values are taken in object reference. C: Default is off. Q: When queried, this flag returns an int. Flag can have multiple arguments, passed either as a tuple or a list.
