在Maya中，有没有办法在约束是寄生节点时查询约束的源和目标？
我正在尝试诊断成为养父母后连接丢失的问题，因此我需要中间信息来与有效的约束进行比较。
我遇到的所有方法都需要建立连接，但是虽然它是一个寄养节点，但这些方法并不存在。 Maya 能够恢复连接，以便信息必须存在于某处。
您可以尝试通过编辑引用来识别约束。打开参考编辑器，然后运行文件>列表参考编辑。这将弹出一个新窗口，该窗口将显示在引用之外进行的所有编辑。此列表可能很大，因此您可以键入约束的名称来筛选结果。
现在，如果您尝试通过脚本访问它，则可以使用cmds.referenceQuery.
将引用节点(而不是养父节点(传递给以下命令：
edit_strings = cmds.referenceQuery("YOUR-REF-NODE", editStrings=True)
edit_nodes = cmds.referenceQuery("YOUR-REF-NODE", editNodes=True)
edit_attrs = cmds.referenceQuery("YOUR-REF-NODE", editAttrs=True)
for line, node, attr in zip(edit_strings, edit_nodes, edit_attrs):
print line, " ::: ", node, ":::", attr
打印输出的结果如下所示：
