明白了，你在 **Maya 2018** 中使用的是 **Python 2.7**，这是 Maya 默认的 Python 版本。你遇到的 `UnicodeEncodeError: ascii` 错误是 Python 2.x 处理中文字符时常见的问题。 --- ## ✅ 解决方案（适用于 Maya 2018 + Python 2.7） ### ✅ 步骤 1：在脚本开头设置默认编码为 UTF-8 ```python # -*- coding: utf-8 -*- import sys reload(sys) sys.setdefaultencoding('utf-8') ``` 这段代码将 Python 2.x 的默认编码从 ASCII 改为 UTF-8，以支持中文字符。 --- ### ✅ 步骤 2：确保脚本文件保存为 UTF-8 编码格式 如果你是在外部编辑器（如 VSCode、Sublime、PyCharm）中编辑脚本，请确保保存为 **UTF-8 without BOM** 格式。 --- ### ✅ 步骤 3：避免在 `print` 和 `cmds.warning` 中直接使用中文字符串（可选） 如果你不想处理编码问题，也可以将提示信息改为英文，避免触发编码问题： ```python print("Selected objects: {0}".format(selected_transforms)) cmds.warning("Please select at least one mesh object.") ``` --- ## ✅ 修改后的完整代码（适配 Maya 2018 Python 2.7） ```python # -*- coding: utf-8 -*- import sys reload(sys) sys.setdefaultencoding('utf-8') import maya.cmds as cmds def create_osd_boundary_tool(): window_name = "osdBoundaryToolWindow" if cmds.window(window_name, exists=True): cmds.deleteUI(window_name) window = cmds.window(window_name, title="OpenSubdiv Controls Tool", widthHeight=(320, 220)) main_layout = cmds.columnLayout(adjustableColumn=True, rowSpacing=10) # ======================== # UV Mode Settings 设置 # ======================== cmds.frameLayout(label="UV Mode Settings", width=300, collapsable=True, collapse=False) boundary_layout = cmds.columnLayout(adjustableColumn=True) mode_menu = cmds.optionMenu(label="UV Boundary Smoothing:") cmds.menuItem(label="None") cmds.menuItem(label="Preserve Edges and Corners") cmds.menuItem(label="Preserve Edges") cmds.menuItem(label="Maya Catmull-Clark") cmds.button( label="Apply to Selected Objects", command=lambda x: apply_osd_boundary_mode(mode_menu), backgroundColor=[0.3, 0.6, 1.0] ) cmds.setParent('..') # 返回上一级布局（frameLayout） cmds.setParent('..') # 返回主布局 cmds.showWindow(window) def apply_osd_boundary_mode(mode_menu): """ 应用选择的 osdFvarBoundary 模式到所选对象 """ mode_index = cmds.optionMenu(mode_menu, query=True, select=True) mode_value = mode_index - 1 # 转换为 0-based 索引 selected_transforms = cmds.ls(selection=True, transforms=True) if not selected_transforms: cmds.warning("请至少选择一个对象！") return for transform in selected_transforms: shapes = cmds.listRelatives(transform, shapes=True) if not shapes: continue for shape in shapes: full_shape = cmds.ls(shape, long=True)[0] if cmds.objectType(full_shape) != 'mesh': continue attr_path = "{0}.osdFvarBoundary".format(full_shape) if not cmds.attributeQuery("osdFvarBoundary", node=full_shape, exists=True): cmds.warning("{0} 不支持 osdFvarBoundary 属性。".format(full_shape)) continue try: cmds.setAttr(attr_path, mode_value) mode_desc = { 0: "None", 1: "Preserve Edges and Corners", 2: "Preserve Edges", 3: "Maya Catmull-Clark" }.get(mode_value, "Unknown") print("✔ 已为 {0} 设置 osdFvarBoundary 为 {1} ({2})".format(full_shape, mode_desc, mode_value)) except Exception as e: cmds.warning("✘ 设置 osdFvarBoundary 失败：{0}，错误：{1}".format(full_shape, e)) # 刷新 OpenSubdiv 预览和 UV 边界显示 refresh_osd_preview(full_shape) force_refresh_uv_boundary(full_shape) def refresh_osd_preview(shape): """切换 useSmoothMeshPreview 属性以刷新细分预览""" attr = "{0}.useSmoothMeshPreview".format(shape) if not cmds.attributeQuery("useSmoothMeshPreview", node=shape, exists=True): return try: current = cmds.getAttr(attr) cmds.setAttr(attr, not current) cmds.setAttr(attr, current) print("✔ 刷新了 {0} 的细分预览".format(shape)) except Exception as e: print("✘ 刷新细分预览失败：{0}，错误：{1}".format(shape, e)) def force_refresh_uv_boundary(shape): """通过 polyOptions 强制刷新 UV 边界显示""" transform = cmds.listRelatives(shape, parent=True, fullPath=True) if not transform: return transform = transform[0] try: cmds.select(transform) cmds.polyOptions(displayUVBorder=True) print("✔ 强制刷新了 {0} 的 UV 边界".format(transform)) except Exception as e: print("✘ 刷新 UV 边界失败：{0}，错误：{1}".format(transform, e)) # 创建工具界面 create_osd_boundary_tool() ``` --- ## 🔍 重点说明 | 问题 | 解决方法 | |------|----------| | `UnicodeEncodeError: ascii` | 添加 `sys.setdefaultencoding('utf-8')` | | Maya 2018 使用 Python 2.7 | 必须手动处理编码问题 | | 文件乱码 | 确保文件保存为 UTF-8（无 BOM） | | 提示信息乱码 | 避免直接使用中文或使用上述编码设置 | --- ##
