Maya:将顶点蒙皮权重复制粘贴到不同命名空间中的对象

如何解决Maya:将顶点蒙皮权重复制粘贴到不同命名空间中的对象

我编写了一个简单的脚本,将顶点关节皮肤值存储在列表中并按选择顺序应用它们,但我需要将值从根命名空间中的对象存储,并将它们应用于不同命名空间中的对象,因为它有相同的关节名称。至少这是我的计划,但 IDK 如何正确地做到这一点。我看到了编辑该 weightsList 的可能性,但它让我感到害怕,因为关节名称位于列表中的列表中。

import maya.cmds as cmds
import pymel.core as pm

def getVertexWeights():
    
    global weightsList 
    weightsList =[]
    meshSkinCluster = ""
    vertexWeightList =[]   
    
    # get all selected vetices in order
    verts = cmds.ls(flatten = True,orderedSelection = True)
    cmds.polyEvaluate( v=True)
    # check is any vertex 
    if len(verts) == 0:
        return cmds.error( "Please select vetices with skin weighs" )
    else:
        obj = cmds.ls(verts[0],objectsOnly = True)
        history = cmds.listHistory(obj) 
    #get mesh skin cluster
        for historyNode in history:
            if cmds.nodeType(historyNode)=="skinCluster":
                meshSkinCluster = historyNode
    #get joint list   
        for each in verts:
            #get weight values
            skinVals = cmds.skinPercent(meshSkinCluster,each,query=True,value=True)
            #get joints list which affect vetex
            jointVals = cmds.skinPercent(meshSkinCluster,transform=None)
            print jointVals
            #clear list before creating child
            vertexWeightList = []
            for i in range(len(jointVals)):
                #clear list every loop
                childList =[] 
                #build list [jointName,weightValue]
                childList.append(jointVals[i])
                childList.append(skinVals[i])
                
                #add values of each influenced joint to the list which will represent one vertex data
                vertexWeightList.append(childList)
            #add each vertexWeightList to the weightsList
            weightsList.append(vertexWeightList)
        cmds.button("applyWeightsBtn",edit=True,enable=True)
        cmds.select(clear=True)
        verts=[]   

def setBorderWeights():
    verts = cmds.ls(flatten = True,orderedSelection = True)
    
    #check if anything selected
    if len(verts) == 0:
        return cmds.error( "Please select vetices with skin weighs" )
    else:
        obj = cmds.ls(verts[0],objectsOnly=True)
        print obj
        
        history = cmds.listHistory(obj) 
        #get mesh skin cluster
        for historyNode in history:
            if cmds.nodeType(historyNode)=="skinCluster":
                meshSkinCluster = historyNode   
        #get namespace
        objNamespace = pm.selected()[0].namespace()
        print objNamespace
        #if there is no namespace apply weight frome the stored list without changes
        if objNamespace=='':
            for i in range(len(verts)):  
                cmds.skinPercent( meshSkinCluster,verts[i],transformValue=weightsList[i])
                print 'no namespace'
        #apply weights from the stored list to selected vertice
        else:
            for i in range(len(verts)):
                for j in range (len(weightsList[i])):
                    tempName = weightsList[i][j][0]
                    weightsList[i][j][0] = objNamespace+tempName
                    print weightsList[i][j][0]
            for i in range(len(verts)):  
                cmds.skinPercent( meshSkinCluster,transformValue=weightsList[i])
        cmds.button("applyWeightsBtn",enable=False)
        cmds.select(clear=True)
        verts=[]    

def showUI():
    if (cmds.window("TransferBorderWeights",exists=True)):
        cmds.deleteUI("TransferBorderWeights")
        
    myWin = cmds.window("TransferBorderWeights",title="Transfer border Weights",resizeToFitChildren=True,maximizeButton=False,widthHeight=(180,200))
    cmds.columnLayout()
    
    cmds.rowLayout(numberOfColumns=2)
    cmds.button("storeWeightsBtn",label="Store Weights",enable=True,command="getVertexWeights()",width=150)
    cmds.button("applyWeightsBtn",label="Apply Weights",enable=False,command="setBorderWeights()",width=150)
    cmds.setParent("..")
    
    cmds.showWindow(myWin)
showUI()

解决方法

脚本无法正常工作,因为未启用有序选择

cmds.selectPref( trackSelectionOrder=1 )
