Maya AbcExport with Python

Question

I have the script to export an Alembic from Maya with MEL :

AbcExport(-frameRange 31 41 -writeVisibility -dataFormat ogawa -root |myChar:char|myChar:GEOchar -file E:/test.abc)

I would like to do the same with Python. Something like :

cmds.AbcExport(...)

I can't find any documentation about it... Any idea?

Thank you a lot!

You can run this command on Python using the jobArg flag:

import maya.cmds as cmd

start = 0
end = 120
root = "-root pSphere1 -root pCube1"
save_name = "c:\documents\maya\project\default\cache\alembicTest.abc"

command = "-frameRange " + start + " " + end +" -uvWrite -worldSpace " + root + " -file " + save_name
cmd.AbcExport ( j = command )

Just tested this with Maya 2016.5, and it works for me.

Like you, I could not find any official documentation showing this, only unofficial sources like these:
