如何把一個 transform 裡存在多個 shapes 的物件獨立出來 (how to separate multiple shapes inside one transform node)

有些工具或外掛會產生出向這種一個 transform 裡存在多個 shapes 的物件。這可能是為了效能關係或其他因素，不過就可能會造成其他一些軟體，工具，或 renderer 無法正常運作。

以下這段小程式可以幫你把這些shapes 拆成"正常"獨立的物件。

	import maya.cmds as mc
	import pymel.core as pm
	def separateShapes(grp=None):
	grp = grp or mc.ls(sl=1)[0]
	SUFFIX = "_separated_geo"
	def getUniqueName(name):
	newName = name
	idx = 1
	while True:
	if not mc.objExists(newName):
	break
	else:
	newName = "{0}_{1}".format(name,idx)
	idx+=1
	return newName
	def getAwesomeName(shapeName):
	name = str(shapeName).split('|')[-1].split(':')[-1].split('.')[0]
	name = name + SUFFIX
	return getUniqueName(name)
	shapes = mc.ls(grp,dag=1,ni=1,shapes=1)
	newTrs = []
	with pm.UndoChunk():
	for eachShape in shapes:
	newName = getAwesomeName(eachShape)
	newTr = mc.createNode("transform", name=newName)
	mc.parent(eachShape, newTr, shape=True, r=True)
	newTrs.append(newTr)
	return newTrs
	separateShapes()
