Crash opening scene with baked controls


I made a rig following steps of the mgear youtube channel. Everything works great but when I save the scene with edited and baked controls I can not open it again, Maya crashes while opening.

I think it is the controls problem because I deleted everything but the controllers_org group, save and open It.

I also tried to export and import them, also crashes. I don’t know if there is a way to print the Stack Trace so I can see where the problem is.

If I bake controls without editing the control shapes, it doesn’t crash.

Thanks a lot.

Hi Andrew.

Are you using Proxy Attributes? Does this thread seem like it addresses your issue?


you can try opening your file with maya 2018

I had the same issue using Maya 2020.1… you can recover the file by opening with 2018, as @c17vfx said.
I think latest Maya 2020 update fixes up the issue, but i kept myself using Maya 2019, which is by far more stable and reliable and didn’t check if this is 100% fixed.



Hi! Thanks a lot. I did this:

And now I have recovered everything.
That’s right, It was because of the Proxy Attributes. I’ve seen Maya has solved this bug in the latest updates. I will keep it turned off, so animators won’t have any problem.
