Maya自定义插件¶

代码所存在的问题类名大驼峰的写法代码不符合PEP8规范代码单引号双引号统一代码使用Git管理测试上线 varName != None改成not varName docstring和注释需要规范

如何编写一个简单的.py插件工具如何在启动的时候 Maya扩展开发的层级结构

插件环境变量部署

# C:\Program Files\Autodesk\Maya2017\modules\hprender.mod
+ hpRender any C:/Users/huweiguo/Documents/.RENDER_ROOT/MayaPlugin/Setup/2017
PATH +:= bin

PATH +:= bin意味着将路径C:/Users/huweiguo/Documents/.RENDER_ROOT/MayaPlugin/Setup/2017/bin路径添加到PATH环境变量中，这里的加bin文件夹并没有任何作用，可以删除

扩展开发层级结构

plug-ins中添加需要加载的插件 scripts中写菜单工具执行的模块代码

Maya环境变量 MAYA_PLUG_IN_PATH 插件文件位置 MAYA_MODULE_PATH mod文件位置 MAYA_SCRIPT_PATH 脚本文件位置 XBMLANGPATH 图标文件位置

Maya.env配置的案例

MTOAROOT = \\server\manager\thirdParty\maya\mtoa\3.1.2.1\2018

REDSHIFT_COREDATAPATH = \\server\manager\thirdParty\maya\Redshift\2.5.48

QAULOTH_PATH = \\server\manager\thirdParty\maya\Qualoth

REDSHIFT_PLUG_IN_PATH = %REDSHIFT_COREDATAPATH%\Plugins\Maya\2018\nt-x86-64
REDSHIFT_SCRIPT_PATH = %REDSHIFT_COREDATAPATH%\Plugins\Maya\Common\scripts
REDSHIFT_XBMLANGPATH = %REDSHIFT_COREDATAPATH%\Plugins\Maya\Common\icons
REDSHIFT_RENDER_DESC_PATH = %REDSHIFT_COREDATAPATH%\Plugins\Maya\Common\rendererDesc
REDSHIFT_CUSTOM_TEMPLATE_PATH = %REDSHIFT_COREDATAPATH%\Plugins\Maya\Common\scripts\NETemplates
REDSHIFT_MAYAEXTENSIONSPATH = %REDSHIFT_PLUG_IN_PATH%\extensions
REDSHIFT_PROCEDURALSPATH = %REDSHIFT_COREDATAPATH%\Procedurals

MAYA_MODULE_PATH = %MAYA_MODULE_PATH%;%MTOAROOT%
PATH = %PATH%;%MTOAROOT%\bin;%REDSHIFT_COREDATAPATH%\bin
MAYA_RENDER_DESC_PATH = %MAYA_RENDER_DESC_PATH%;%MTOAROOT%;%REDSHIFT_RENDER_DESC_PATH%
PYTHONPATH = %PYTHONPATH%;%MTOAROOT%\scripts;%REDSHIFT_SCRIPT_PATH%
MAYA_PLUG_IN_PATH = %REDSHIFT_PLUG_IN_PATH%;%QAULOTH_PATH%\bin
MAYA_SCRIPT_PATH = %REDSHIFT_SCRIPT_PATH%;%QAULOTH_PATH%\script
XBMLANGPATH = %REDSHIFT_XBMLANGPATH%
MAYA_CUSTOM_TEMPLATE_PATH = %REDSHIFT_CUSTOM_TEMPLATE_PATH%

MAYA_DISABLE_CLIC_IPM = 1

来看下如何写个py的插件到插件管理器吧，分两步注册插件 C:UsershuweiguoDocuments.RENDER_ROOTMayaPluginSetup2017plug-ins hpRender.py

如何创建自定义菜单

sys.path模块导入机制 import hpMayaClient reload(hpMayaClient) hpMayaClient.client().main()

main函数的核心 checkList 检测客户端是否安装检测C盘是否有读写权限检测文件是否保存检测每一层渲染层的渲染帧数范围，这块没必要用正则表达式，可以直接获取 cmds.getAttr(“defaultRenderGlobals.startFrame”) 分析渲染层的函数如何获取当前场景中用到的所有插件如何获取当前场景中用到的所有资产文件 cmds.file(query=True, list=True, withoutCopyNumber=True) ver.ini检测Maya版本信息检测插件版本C:UsershuweiguoDocuments.RENDER_ROOTMayaPluginmayaPluginItems_2017.ini 检测每一层的渲染设置 UI cmds.window 窗口如果存在删除控件(button, text, intFieldGrp, checkBox, textFieldGrp, radioButtonGrp) 布局
