I've tried following SublimeREPL instructions for setting default_extend_env.
I tried:
"default_extend_env": {"PATH": "{PATH}:C:/Program Files/Autodesk/Maya2016/bin/mayapy.exe"}
I also tried: "default_extend_env": {"PATH": "{PATH}:C:/Program Files/Autodesk/Maya2016/devkit/other/pymel/extras/completion/py"}
I wasn't sure what the difference was between default_extend_env and python_virtualenv_paths so I tried adding those file paths under "python_virtualenv_paths" as well.
With any of those combinations, I couldn't even get any of the python interpreter options available in SublimeREPL to load the pymel module.
The option "Python - virtualenv" under Tools>SublimeREPL>Python> doesn't do anything either. When I try the python/ipython option, the window pops up as expected.
I have my sublime project set up properly with Jedi and sublime-code-intel so auto completion works.
Any help with this would be greatly appreciated!
