Maya权重拷贝工具：窗口化批量操作

在Maya中进行模型绑定时，经常需要将一个模型的权重信息拷贝到另一个模型上。为了提高效率，本教程将介绍如何使用PyQt或PySide2库创建一个自定义的Maya窗口工具，实现便捷的权重拷贝功能。

Python代码示例 (使用PySide2)pythonimport maya.cmds as cmdsfrom PySide2 import QtWidgets

class CopyWeightsWindow(QtWidgets.QDialog): def init(self, parent=None): super(CopyWeightsWindow, self).init(parent) self.setWindowTitle('Copy Weights') self.setMinimumWidth(300) self.source_obj = None self.target_objs = [] self.create_widgets() self.create_layout() def create_widgets(self): self.source_label = QtWidgets.QLabel('Source Object:') self.source_line_edit = QtWidgets.QLineEdit() self.source_button = QtWidgets.QPushButton('Load') self.source_button.clicked.connect(self.load_source_object) self.target_label = QtWidgets.QLabel('Target Objects:') self.target_line_edit = QtWidgets.QLineEdit() self.target_button = QtWidgets.QPushButton('Load') self.target_button.clicked.connect(self.load_target_objects) self.copy_button = QtWidgets.QPushButton('Copy Weights') self.copy_button.clicked.connect(self.copy_weights) def create_layout(self): layout = QtWidgets.QFormLayout() layout.addRow(self.source_label, self.source_line_edit) layout.addWidget(self.source_button) layout.addRow(self.target_label, self.target_line_edit) layout.addWidget(self.target_button) layout.addWidget(self.copy_button) self.setLayout(layout) def load_source_object(self): self.source_obj = cmds.ls(selection=True)[0] self.source_line_edit.setText(self.source_obj) def load_target_objects(self): self.target_objs = cmds.ls(selection=True) self.target_line_edit.setText(', '.join(self.target_objs)) def copy_weights(self): if self.source_obj and self.target_objs: cmds.select(self.source_obj) for target_obj in self.target_objs: cmds.select(target_obj, add=True) cmds.copySkinWeights(noMirror=True, surfaceAssociation='closestPoint', influenceAssociation='oneToOne') print('Weights copied successfully!') else: print('Please select source and target objects first.')

创建窗口实例并显示window = CopyWeightsWindow()window.show()

使用方法

确保Maya中已安装PyQt或PySide2库。2. 将代码复制并保存为Python文件 (例如 copy_weights_tool.py)。3. 在Maya的脚本编辑器中执行以下代码以运行工具：pythonimport copy_weights_to
