python-2.7 - Maya：将顶点蒙皮权重复制粘贴到不同命名空间中的对象

问题描述

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，但我需要将来自对象的值存储在根命名空间中并将它们应用于不同命名空间中的对象，因为它具有相同的关节名称。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 weightsList 的可能性，但它让我害怕，因为联名位于列表中的列表中的列表中。

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, each, query=True, 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, verts[i], transformValue=weightsList[i])
        cmds.button("applyWeightsBtn",edit=True, 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()
