快速开始

如果你的Maya有pip那么

cd "C:\Program Files\Autodesk\Maya2022\bin"
mayapy -m pip install cpref

如果没有

1. 打开C:\Users\PC\Documents\maya文件夹
2. 进入scripts文件夹，如果没有就创建它
3. 下载完整的cpref代码
4. 解压并进入解压完成的文件夹
5. 将src目录中的cpref文件夹复制到scripts
6. 打开maya，如果已经打开了就重启它
7. 打开脚本编辑器并执行以下示例代码

import maya.mel as mel
from cpref.object_ref import Ref

mel.eval("""polySphere -r 1 -sx 20 -sy 20 -ax 0 1 0 -cuv 2 -ch 1 -n test_poly;
doGroup 0 1 1;
doGroup 0 1 1;
doGroup 0 1 1;
doGroup 0 1 1;
doGroup 0 1 1;
setKeyframe {"group5"};""")
r = Ref("test_poly")
print("Ref __init__ >>", r)
print("Ref is_null >>", r.is_null())
print("Ref as_string >>", r.as_string())
print("Ref as_string_list >>", r.as_string_list())

功能介绍

Maya节点引用

Maya节点引用功能提供了对Maya节点长期引用
