pymel.core.modeling.subdMapSewMove¶

subdMapSewMove(*args, **kwargs)¶

This command can be used to Move and Sew together separate UV pieces along geometric edges. UV pieces that correspond to the same geometric edge, are merged together by moving the smaller piece to the larger one. The argument is a UV selection list.

Flags:

Long Name / Short Name		Argument Types	Properties
caching / cch		bool
	Toggle caching for all attributes so that no recomputation is needed
constructionHistory / ch		bool
	Turn the construction history on or off.
frozen / fzn		bool
limitPieceSize / lps		bool
	When on, this flag specifies that the face number limit described above should be used.
name / n		unicode
	Sets the name of the newly-created node. If it contains namespace path, the new node will be created under the specified namespace; if the namespace does not exist, it will be created.
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 Common flags
numberFaces / nf		int
	Maximum number of faces in a UV piece. When trying to combine two UV pieces into a single one, the merge operation is rejected if the smaller piece has more faces than the number specified by this flag.This flag is only used when limitPieceSizeis set to on.
worldSpace / ws		bool
	If true, performs the operation in world space coordinates as opposed to local space. Flag can have multiple arguments, passed either as a tuple or a list.

Derived from mel command maya.cmds.subdMapSewMove

Example:

import pymel.core as pm

# Create a subd sphere with default UVs.
import maya.mel as mel
mel.eval( "createSubdSphere" )

# Automatic projections with 6 planes.
pm.subdAutoProjection( 'subdivSphere1.smf[*][*]' )
# Result: [u'subdAutoProj1'] #

# Select the seams
pm.select( 'subdivSphere1.sme[0:1][67108864]', 'subdivSphere1.sme[256][67108867]', 'subdivSphere1.sme[513][67108864]' )

# merge them, with the appropriate move.
pm.subdMapSewMove()
# Result: [nt.SubdMapSewMove(u'subdMapSewMove1')] #
