polyColorMod(*args, **kwargs)¶

Modifies the attributes of a poly color set.

Flags:

Long Name / Short Name		Argument Types	Properties
alphaScale_FloatValue / afv		float
alphaScale_Interp / ai		int
	????? Default:0
alphaScale_Position / ap		float
baseColorName / bcn		unicode
	The name of the color set to be modified.
blueScale_FloatValue / bfv		float
blueScale_Interp / bi		int
	????? Default:0
blueScale_Position / bp		float
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.
frozen / fzn		bool
greenScale_FloatValue / gfv		float
greenScale_Interp / gi		int
	????? Default:0
greenScale_Position / gp		float
huev / h		float
	Huerotates hue value of the final color. Default:0.0
intensityScale_FloatValue / nfv		float
intensityScale_Interp / ni		int
	????? Default:0
intensityScale_Position / np		float
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
redScale_FloatValue / rfv		float
redScale_Interp / ri		int
	????? Default:0
redScale_Position / rp		float
satv / s		float
	Satscales the staturation of the final color. Default:1.0
value / v		float
	Valuescales the final color value. Default:1.0 Flag can have multiple arguments, passed either as a tuple or a list.

Derived from mel command maya.cmds.polyColorMod

Example:

import pymel.core as pm

# Create a poly plane pPlane1
pm.polyPlane(w=10, h=10, sx=10, sy=10, n='pPlane1')

# Create colorSet1 , set to use RGBA channel
pm.polyColorSet(create=True, clamped=0, rpt='RGBA', colorSet='colorSet1')
# Apply red color to the vertices of pPlane1
pm.polyColorPerVertex(r=1, g=0, b=0, a=1, cdo=True)

# Modified the color of colorSet1 to green
pm.polyColorMod('pPlane1',huev=120, bcn='colorSet1')
