ID 611328 - The filenameFilter callback and the Path Substitutions Preferences do not work as expected

def myFilenameFilter(filename):    new_filename = filename.replace("C:/fake/", "C:/temp/")    print(filename, new_filename)    return new_filenamenuke.addFilenameFilter(myFilenameFilter)

C:/fake/AwesomePicture.jpeg C:/temp/AwesomePicture.jpeg

However, the Read node will still be in an error state.
 
 
Steps to reproduce - Path Substitutions
 
1) Open Nuke.
 
2) Create a Read node.
 
3) Set its file knob to a path/file that doesn't exist. For example: C:/fake/AwesomePicture.jpeg
 
4) Save and close the script.
 
5) In Edit > Preferences > General > Path Substitutions, set the path for your current OS to a real path and the path on another OS to the path on your Read node.
In this case, this should resolve the Read node's file path to C:/temp/AwesomePicture.jpeg on Windows. This file will need to exist on your system:
 

 
6) Close and reopen Nuke, to ensure the Preferences take affect.
 
7) Reopen the script.
 
 
Steps to reproduce - OCIO config path
 
1) Open Nuke.
 
2) In Project Settings (Edit > Project Settings) and set the following:
 

• color management to OCIO
• OCIO config to custom
• custom OCIO config to the path of one of your config files (ie. /fake/<username>/Documents/ocio/config.ocio)

def myFilenameFilter(filename):    new_filename = filename.replace("/fake/", "/home/")    print(filename, new_filename)    return new_filenamenuke.addFilenameFilter(myFilenameFilter)

import nukedef ocioPathUpdate():    filename = nuke.root()["customOCIOConfigPath"].value()    if nuke.env['MACOS']:         filename = filename.replace( 'C:/Users', '/home/user' )     else:         filename = filename.replace( '/home/user', 'C:/Users' )     nuke.root()["customOCIOConfigPath"].setValue(filename) nuke.addOnScriptLoad(ocioPathUpdate) 

import nukedef readPathUpdate():    filename = nuke.thisNode()["file"].value()     if nuke.env['MACOS']:        filename = filename.replace( 'C:/Users', '/home/user' )    else:        filename = filename.replace( '/home/user', 'C:/Users' )    nuke.thisNode()["file"].setValue(filename)nuke.addOnCreate(readPathUpdate, nodeClass="Read")
