Marcus is right. subprocess is the best way. me likey.
However. you’re using pymel so before you begin be sure and set an
environment variable to turn *off *initializing plugins. Chad Vernon sussed
out this crash a week or two ago on this group.
so set this variable if you’re on widows in your environment vars:
set PYMEL_SKIP_MEL_INIT = 1;
or on linux:
setenv PYMEL_SKIP_MEL_INIT 1
test it before hand to make sure it’ll work in subprocess. you don't want
to hunt down two different issues.
in a shell type:
mayapy
you should get a python prompt then test this to make sure you don't get a
traceback. then you're ready to convert your code below to a subprocess
call.
import maya.standalone
maya.standalone.initialize()import osimport pymel.core as pm
# you should see this next line if you set the environment variable
correctly.#pymel.internal.startup : INFO : Skipping MEL initialization
cube = pm.polyCube()
## your code goes here
pm.saveAs("someFile.ma")# result: Path('someFile.ma')
os._exit(0)
