hello
i tried to create exe from script called : change_mxs_reference.py
i have one problem with the new output mxs
when i change the place of the name group ( see image ) i got different errors ; the problem maybe there but i don't find solution

i find the problem
scene = mw.Cmaxwell(mw.mwcallback);
ok = scene.readMXS(self.edit_mxs_file.text().toAscii().data());
inPath = self.edit_mxs_folder.text().toAscii().data()
mxsList = ['scene.mxs']
old = self.edit_old_mxsref.text().toAscii().data()
new = self.edit_new_mxsref.text().toAscii().data()
outFolder = self.edit_output.text().toAscii().data()

how i can choose a file from folder ; when i do that with open button it take the full name with path

hi ; the script read all files in the folder and replace the mxs ref but create new mxs ref and new name in every scene :
refA ; refA1 ; refA2 ...
how i can fix that ?

Code: Select all

        for mxs in mxsList:

            scene.readMXS(inPath+'/'+mxs)

            it = CmaxwellObjectIterator()
            obj = it.first(scene)

            while not obj.isNull():
                mxsRef = obj.getReferencedScenePath()

                if mxsRef == old:
                    # replace MXS reference path
                    obj.setReferencedScenePath(new)
                    #obj.setName(newname)
                    print('Object: ' + obj.getName()[0] + '. MXS path replaced')


                obj = it.next()

            outputpath = outFolder + '/' + mxs
            scene.writeMXS(outputpath)

I ran your code and I can't reproduce the problem. I don't see any problem there.

Thanks
The problem if i load a folder with many mxs files, the script change the mxsref in the first scene
In the second create other mxsref with name "mxref"1
In the third scene create two other mxref with names : "mxref"1, "mxref"2
....etc

I see the problem now! There is an issue in readMXS(...), internally it does not the previous readed scene (in case any scene was readed), so you have to make sure that the scene is clean before calling readMXS, so you can solve this in two ways:

creating the scene variable on each loop iteration:

Code: Select all

for mxs in mxsList:
    scene = Cmaxwell(mwcallback)
    scene.readMXS(os.path.join(inDir,mxs))
    ...

cleaning the scene at the end of the loop:

Code: Select all

for mxs in mxsList:
    scene.readMXS(os.path.join(inDir,mxs))
    ...
    scene.freeScene()

very clever ; thank you Brany

Code: Select all

        for mxs in mxsList:

            scene.readMXS(os.path.join(inPath, mxs))

            it = CmaxwellObjectIterator()
            obj = it.first(scene)

            while not obj.isNull():
                mxsRef = obj.getReferencedScenePath()

                if mxsRef == old:
                    # replace MXS reference path
                    obj.setReferencedScenePath(new)
                    obj.setName(newname)
                    print('Object: ' + obj.getName()[0] + '. MXS path replaced')


                obj = it.next()

            outputpath = outFolder + '/' + mxs
            scene.writeMXS(outputpath)
            scene.freeScene()

Hello; before i tried many times the code and worked find but tonight didn't work ; than i tried the same code in maxwell folder but didn't work and the mxsref don't changed.
tested with pymaxwell for v3 and pymaxwell for v4

Code: Select all

	# loop over all mxs

	for mxs in mxsList:

			print('ERROR: cannot open '+inPath+'/'+mxs)
			return 0

		# loop over all objects

		it = CmaxwellObjectIterator()
		obj = it.first(scene)

		while not obj.isNull():
			mxsRef = obj.getReferencedScenePath()

				# replace MXS reference path

				obj.setReferencedScenePath(newMxsRef)

	outFolder = 'C:/Users/archi/Desktop/examples/mxsRef/output'

	if replaceMxsReferenceByPath(oldMxsRef,newMxsRef,inPath,mxsList,outFolder):
		print 'OK'

Posted: **Sat Sep 23, 2017 6:45 pm**

i think the problem solved because the script always read the mxsRef path
i make a change so it read the name of the mxsref
i will test more
