I'm a little confused. I tried running your script and it most definitely
didn't work (for more than a few reasons) but it seems like you're very
confused about what functions to use and where. I've converted your script
to PyMel (just to show, and also modified the cmds version). Seems like
you think you're working with actual "files" but in reality the "file" is
really just a path as a string not a system file. So you would just do
either string manipulation or use manipulate with os.path functions. You
don't need to use copy2 as a function since that's more of an actual system
file command rather than string manipulation. (I also added in the way to
get your PROJECT environment variable for fun.
*PYMEL*
*import pymel.core as pm*
* *
*import os*
* *
*files = pm.ls(type="file")*
* *
*project_path = os.getenv('MAYA_PROJECT')*
* *
*def myCopy (path):*
* *
* return path.replace('/','') #does both / and //...*
* *
*for item in files:*
* *
* fileNode = pm.PyNode(item)*
* *
* fileNode.fileTextureName.set(myCopy(project_path), type='string')
#setting the new path*
* *
* print fileNode.fileTextureName.get() #echos back old file path!!!!!!!*
*CMDS*
*import maya.cmds as cmds*
* *
*import os*
* *
*files = cmds.ls(type="file")*
* *
*project_path = os.getenv('MAYA_PROJECT')*
* *
*def myCopy (path):*
* *
* return path.replace('/','') #does both / and //...*
* *
*for item in files:*
* *
* cmds.setAttr( "%s.fileTextureName"%item, myCopy(project_path),
type='string') #setting the new path*
* *
* print cmds.getAttr( "%s.fileTextureName"%item) #echos back old file
path!!!!!!!*
