Hey guys,
I have tried the solution to launch multiple Maya's. At first I split my
iteration dictionary into 2 and ran the 2 Mayas in parralell which produced
the same fatal error. So I split it into 4 and made ach Maya wait for the
other to finish but I am still getting the same error on the same file in
any case regardless of how many Maya processes I open up.
As I stated earlier the file can be loaded normally or by script on it's
own. Is there any way I can test files for fatal errors or any suggestions
in debugging these particularly troublesome files?
d = UTILS.linch_dict_divider(mayaFiles, 4)
mayaExe = os.environ['MAYA_EXE']
mayaRunScript = os.environ['BATCH_CONVERT']
mayaSplitDict1 = d[0]
mayaSplitDict2 = d[1]
mayaSplitDict3 = d[2]
mayaSplitDict4 = d[3]
p1 = subprocess.Popen([mayaExe, '-script',
mayaRunScript,str(mayaSplitDict1)],
stdout=subprocess.PIPE,
stderr=subprocess.STDOUT)
p1.communicate()
p2 = subprocess.Popen([mayaExe, '-script', mayaRunScript,
str(mayaSplitDict2)],
stdout=subprocess.PIPE,
stderr=subprocess.STDOUT)
p2.communicate()
p3 = subprocess.Popen([mayaExe, '-script',
mayaRunScript,str(mayaSplitDict3)],
stdout=subprocess.PIPE,
stderr=subprocess.STDOUT)
#subprocess.Popen.communicate(subprocess.Popen)
p3.communicate()
p4 = subprocess.Popen([mayaExe, '-script', mayaRunScript,
str(mayaSplitDict4)],
stdout=subprocess.PIPE,
stderr=subprocess.STDOUT)
p4.communicate()
