Possible Maya bug: Loading editMB into Maya via cmds.file()

[Fredrik Averpil]

I think I found a bug in Maya. After having fiddled around with reference edits in a script, something broke and it is impossible to load an “editMB” file back into Maya using Python or MEL. See the example script below. Step 4 won't work.

However, if you re-open the scene after having run this code and then run the code for step 4 … it works, and the reference edits are loaded back in successfully. So it seems a re-open of the scene is needed for step 4 to work properly when chaining these commands in a script.

And if you right-click the reference and choose “Assign offline file” and assign a file that way, it just works without re-opening the scene. My problem is I have to automate this using a script.

Anyone understand what’s going on?

for ref in cmds.ls(references=True):
    print 'Working on ' + ref

    # Step 1. Export edits
    print 'Exporting edits to C:/...'
    cmds.exportEdits(
                        'C:/'+ref.replace(':','')+'.editMB',
                        type='editMB',          # default
                        onReferenceNode=ref,    # default
                        includeNetwork=True,    # default
                        includeAnimation=True,  # default
                        includeShaders=True,    # default
                        includeSetAttrs=True,   # default

                        includeSetDrivenKeys=True,
                        includeConstraints=True,
                        includeDeformers=True,

                        force=True
                    )

    # Step 2. Remove all edits
    print 'Removing all edits...'
    cmds.file(unloadReference=ref)
    cmds.file (cr=ref) # cleanReference
    cmds.file(loadReference=ref)


    # Step 3. Save down new edits into maya reference files
    print 'Saving down new edits into reference...'
    filepath = cmds.referenceQuery( ref, filename=True )
    cmds.file(filepath, saveReference=True, force=True)


    # Step 4. Apply the original reference edits back onto the reference files
    print 'Apply reference edits from file in C:/...editMB back into reference...'
    cmds.file( 'C:/'+ref.replace(':','')+'.editMB', applyTo=ref, i=True, namespace=ref.replace(':',''), type='editMB')

Hi sir did you find an answer for this??

Thanks!!

Nope, it was too unreliable so I ended up abandoning that approach.
