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

includeAnimation=True, # default
includeShaders=True, # default

)
# 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')
