Hi, I was using mgear 3.4 and was working fine. Since I switched to 3.7 and using UI options I’m getting this error “maya\modules\scripts\mgear\core\dagmenu.py line 217: ‘NoneType’ object is not iterable” and also maya is crashing while using controllers to select UI host.
Using maya 2019.3.1 on windows.
Thanks for the feedback @Mani
the rig has been generated with the 3.7 version? or is from older version?
Thanks @Miquel for the reply. I was using @Milio rig to test some of the animations. So, I guess its from older version. Also, I have created some of the rigs using 3.6 those are having the same issue’s(crashing while using any of the controller to select UI host).
Hello @Mani
Have you tested in Maya 2020? Maya 2019, in my opinion is full of bugs and not worth using.
Also I tweeted this potential fix for when Maya crashes when you touch a rig. Give it a try. It might help. It helped with several animators so far.

- uncheck “Include Controllers in Evaluation Graph” (most important one to try.)
- uncheck “GPU override” (This might not make a difference. And it might slow down your rig. Try keeping it on at first, then disable it if you keep crashing.)
- Restart Maya. (Won’t help before restarting.)
This seems to have worked a few times. (Not always!)
Thanks @chrislesage! Thanks for the suggestion. No, I didn’t try in maya 2020 as some of my client are using 2019 but will try for personal test. But on a side note, when I am building rig using 3.7 in maya 2019 its working fine and no crashes, it’s only when I am using any rigs which are build in lower version of mgear. Will give it a try at those fix’s.
Hello @Mani
Yes the error is expected since the new rigs have a new message connection and attribute to handle the right-click menu.
I will check how to add a handler to avoid the error and crash. But not planning to support old rigs with the right-click menu. You will need to rebuild rigs to use 3.7 right-click menu.
Sure, thanks for the info! BTW love the mgear XDXD

Hello @Mani I have tried old rigs on the latest mGear with Maya 2020 and didn’t get any crash. I will try with Maya 2019 at some point. But since is not a version I am using in production it may take a while to test
Do you have any news on your side? did you try Maya 2020?
Hi @Miquel thanks for the effort. Yes, seems working fine in Maya 2020 and no crashes…yeahhh!
But I am getting same error while using any function from UI Host Only IK to FK functions:
\maya\modules\scripts\mgear\core\dagmenu.py line 217: ‘NoneType’ object is not iterable
yes, that is already fixed.
The fix will be on the next beta
