很实用的一篇文章，在这里推荐给大家。

往往我们拿到一些客户灯光整合文件中存在很多代理文件，比如Arnold的ass文件，Redshift的rs文件，正常来说这些代理文件不会二次赋予材质，材质都是写在代理文件里面的，材质的贴图路径你是看不到的，但是我们又必须check这些贴图是否存在，这里有两段代码，分别获取rs文件和ass文件的所使用到的贴图路径，运行代码很简单，打开Maya，随便导一些ass文件或者rs文件进来，然后在Script Editor中执行下面的Python代码即可获得所有贴图路径（这两段代码来自羊厂长打包王工具里的部分代码），代码到用时方恨少。

获取Redshift渲染器rs代理文件所有贴图路径代码:

import reimport codecsfrom pprint import pprint
import maya.cmds as cmds
def readFileCode_bag2(path):
con = ""
if os.path.exists(path):Arg = codecs.open(path, "r")con = Arg.read()Arg.close()
return con
getAllRs = []getAllNodes = cmds.ls(type="RedshiftProxyMesh")
tm = re.compile("(\\x00\\x00\\x00[A-Za-z]:/.*?\\x00)+")tm2 = re.compile("(\\x00\\x00\\x00//[0-9].*?\\x00)+")
for node in getAllNodes:getPath = cmds.getAttr(node + ".fileName")
if getPath and getPath not in getAllRs:getAllRs.append(getPath)
for oneProxy in getAllRs:getAllPath = []print(oneProxy)getCon = readFileCode_bag2(oneProxy)getResult = tm.findall(getCon)getResult2 = tm2.findall(getCon)
for oneString in getResult:if oneString and "\\" not in oneString and "_map_auto" not in oneString and "/" in oneString:getPathMap = oneString.split("\x00\x00\x00")[1][:-1]if getPathMap and getPathMap not in getAllPath:getAllPath.append(getPathMap)
for oneString in getResult2:if oneString and "\\" not in oneString and "_map_auto" not in oneString and "/" in oneString:getPathMap = oneString.split("\x00\x00\x00")[1][:-1]if getPathMap and getPathMap not in getAllPath:getAllPath.append(getPathMap)
pprint(getAllPath)

获取Arnold渲染器ass代理文件所有贴图路径代码:

from pprint import pprintimport maya.cmds as cmds
import arnold as ar

# 分析ass代理文件贴图路径getAllAss = []getAllNodes = cmds.ls(type="aiStandIn")
for node in getAllNodes:getPath = cmds.getAttr(node + ".dso")
if getPath and getPath not in getAllAss:getAllAss.append(getPath)
for ass in getAllAss:getAllPath = []print(ass)ar.AiBegin()ar.AiMsgSetConsoleFlags(ar.AI_LOG_ALL)ar.AiASSLoad(ass, ar.AI_NODE_ALL)iterator = ar.AiUniverseGetNodeIterator(ar.AI_NODE_ALL)
while not ar.AiNodeIteratorFinished(iterator):node = ar.AiNodeIteratorGetNext(iterator)
if ar.AiNodeIs(node, "MayaFile") or ar.AiNodeIs(node, "image"):getPath = ar.AiNodeGetStr(node, "filename")
if getPath and getPath not in getAllPath:getAllPath.append(getPath)
ar.AiNodeIteratorDestroy(iterator)ar.AiEnd()pprint(getAllPath)

End
