優(yōu)化了下https://www.bilibili.com/read/cv6298807/UP提供的代碼 評論區(qū)發(fā)送代碼會改變字符串， 本來是英文的（）的括號會變成這個【】 導(dǎo)致復(fù)制也運行不了

以下是代碼

import maya.cmds as cmds

def separate_obj(merger):

merger_shape = cmds.listRelatives(merger, s=True)[0]

all_sg = cmds.listSets(object=merger_shape, type=1)

for sg in all_sg:

locals()[sg] = []

components = cmds.polySeparate(merger, ch=False)

parent_grp = cmds.listRelatives(components[0], parent=True)

for element in components:

sg_name = cmds.listSets(object=cmds.listRelatives(element, s=True)[0])[0]

locals()[sg_name].append(element)

for sg in all_sg:

if len(locals()[sg]) == 1:

cmds.rename(locals()[sg][0], (merger + "_" + sg))

cmds.sets(locals()[sg][0], forceElement=sg)

else:

part = cmds.polyUnite(locals()[sg], ch=False, n=(merger + "_" + sg))

cmds.sets(part, forceElement=sg)

cmds.parent(part, parent_grp)

for obj in cmds.ls(selection=True):

separate_obj(obj)

下面是給工作中需要用到這個代碼的魔改版，會根據(jù)用戶的材質(zhì)球用戶自定義名字賦予分離的模型，比如用戶的材質(zhì)球名字是 H2333_LOW 分離模型后名字為H2333_LOW_Geo,

以下是代碼

import maya.cmds as cmds

def separate_obj(merger):

merger_shape = cmds.listRelatives(merger, s=True)[0]

all_sg = cmds.listSets(object=merger_shape, type=1)

for sg in all_sg:

locals()[sg] = []

components = cmds.polySeparate(merger, ch=False)

parent_grp = cmds.listRelatives(components[0], parent=True)

for element in components:

sg_name = cmds.listSets(object=cmds.listRelatives(element, s=True)[0])[0]

locals()[sg_name].append(element)

for sg in all_sg:

if len(locals()[sg]) == 1:

obj_name = locals()[sg][0]

shader_name = cmds.listConnections(sg + ".surfaceShader")[0]

new_name = shader_name + "_Geo"

cmds.rename(obj_name, new_name)

cmds.sets(new_name, forceElement=sg)

else:

obj_list = locals()[sg]

shader_name = cmds.listConnections(sg + ".surfaceShader")[0]

new_name = shader_name + "_Geo"

part = cmds.polyUnite(obj_list, ch=False, n=new_name)

cmds.sets(part, forceElement=sg)

cmds.parent(part, parent_grp)

for obj in cmds.ls(selection=True):

separate_obj(obj)
