Chain_01 FK/IK switch error

Hello!

When using the chain_01 component in the FK/IK mode, the FK/IK switch seems to error out in transform.py: ‘NoneType’ object has no attribute ‘getMatrix’

Does anyone have experience with successfully using the FK/IK switch on the chain_01 component?

Thank you.

Hi, what version of mGear, what version of Maya?

Hi Chris,

It’s Maya 2025. mGear: 5.0.5

Hello,

Just wanted to check if the Chain FK/IK switch is working for anyone else. If so, please let me know. It could be due to the Maya or mGear version like Chris eluded to but I’m not sure how to resolve the issue currently.

Thank you!

Like using mobu, I’m a big fan of ik fingers as a feature, but I think this has been like this for quite a long time.

Error: AttributeError: file C:\Users\Milio_PC\Documents\maya\modules\scripts\mgear\core\transform.py line 589: ‘NoneType’ object has no attribute ‘getMatrix’

Thank you for looking at it @Milio!
Yes, I’m getting the same ‘NoneType’ object has no attribute ‘getMatrix’ error.
Good to know that it’s not just me encountering the error. Thank you.

I need to fix this one ASAP :sweat_smile:
