Hey there - we had a similar issue with a python plugin in 2016, and it turned out to be related to the new multi threaded graph evaluation and the python GIL. Try turning that off in the prefs and see if it works.
If that is the cause, you can try a fix suggested by a fine fellow at autodesk: set the environment variable $MAYA_RELEASE_PYTHON_GIL to 1 before launching maya, and hopefully it works. According to autodesk support, setting this on has no adverse side effects, but I'm leery - if so, why not have it on by default? That said, it's worked for us beautifully so far, without any noticeable issues... On Sat, Oct 31, 2015, 3:36 AM Bob Loblaw <[email protected]> wrote: > Interesting but inconclusive.
